Taken from the Cyanogen mod for Viewsonic G tablet, the DSP manager + associated DSP Manager, will enhance your audio just a little bit.
If its liked and no serious problems found, ill add this to my next Mod update.
attached file should be renamed to "update.zip" and install just like other patches for the FolioMod's.
Let me hear some feedback, both good and bad
i ve just installed it on tntmod 0,4 and it works fine, i was looking for a equalizer and you made this update, thanks it' s a good start, i was using the equalizer of my milestone audio effect and it works good too.
many thanks

nice, you mean the AudioEffects application? that one i have on my milestone too ill test that one too..
yes that one, i think it's a efficient one with good headphones, thanks Moto
Works for me, not sure if I need it, but will try with a portable speakers setup to see how the headphone output level compares (I think the built-in speakers are very close to junk)

close? you must mean those are junk.. they didnt invest much in sound here
Im gonna check the Moto App, as it was quite ok on milestone and see if external speakers too sound like on my milestone. then its for sure included in next update.
The moto one is definitely the best with headphones with custom mode extra bass and so but with the speakers it s not as efficient as with the milestone speakers
the headset settings has no effect since it seems the folio is just routing the phonespeaker channel to the headset when you plug them in. so basically we just have eq.
is not able to test bluetooth.
The Sound seems to be louder(right word ??) by default...
great!
Motorola S9 seems to work on Blutooth - the difference is clear to hear
Works on my folio.
Bluetooth not tested yet.

Well, I was unsure if I should post this under one of the old posts, but I decided to start it as a new clean post...
Many are having problem with "hissing" noise, joint-stereo and low bitrate(or bitpool). For my sake, I've tried "fit4cat - Hermes Tweaker", "Sleuth255 A2DP fix" and several other methods, but without beeing able to get the soundquality I want from my headset.
Now, this is what worked for me after tweaking around with the registry a while, and endless pairing sessions
Download a registry editor(I use PHM, http://www.phm.lu/Products/PocketPC/RegEdit/ <- Download the PocketPC 2002/2003 ARM/PXA)
1: Turn off bluethooth on the Trinity
2: Unpair the Trinity with the headset(Delete the headset from the list!)
3: Change the following registry settings:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Bluetooth\A2 DP\Settings
MaxSupportedBitPool=80
MinSupportedBitPool=40 (or more if you want)
(if these arn't there, add them!)
And DELETE:
UseJointStereo = 0/1 (depending on whatever you have put there before)
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\WaveDev]
Priority256=149
(let the rest be as it is)
4: Reboot
5: Now, DO NOT use the headset for direct pairing!(since you've already added your phone to the headset, pressing a button on it will useually pair it back with the Trinity) <- This seems to be the function that triggers the sound-problem...
Instead, set the headset in visible mode, and use the trinity to pair(search for new devices), when you find the headset and pair it, you will hear the pairing-sound from the trinity-speaker, and NOT the headset.
Now you can enjoy high quality stereo sound without any disturbance
But, the problem comes when you turn off your Trinity, or the headset. If you try to connect the headset and the phone by using the connectbutton/playbutton on the headset, it will pair, but this time you will hear the pairing sound in the headset, and then you have all your problems back... So then you have to turn of bluethooth, delete the headset from the trinity, and add it back once again by turing the headset in visible mode again.
So the solution to this, is to go to the device list on the trinity after you have lost connection with the headset(this is if you have turned of the trinity or the headset), and hold the stylus on it and choose "Use as wirelss stereo" and "use as handsfree"...
Thanks to all of you guys here who have posted solutions to the A2DP problems And if anyone have suggestions to other values that are better fit then the onces I've supplied, share them with us
And if all of this have been posted in another thread that I've missed out, the moderators are free to delete this one
Good grief, I can only imagine how many times you had to pair the headset before you noticed what was going on LOL, hope you didn't turn blue in the face
I imagine a ROM update could fix this problem.

Hehe! The thing that made me going was that I was able to get perfect sound once or twice, and since I made it work those few times I just had to find out what I actually did that made this work (And paying 175$ for the headset also keept me fueled for a while ) hehe!
I think I've used about 5-6 hours total these two days sitting pairing, adjusting settings, rebooting(ARGH!), untill I found out that the problem actually occurs when you use the headset to pair instead of the trinity
I don't understand what is it with bluetooth stereo:
quality is not good enough to listen to music 64 kbps... no bass, no medium, nothing just a hiss.
and plus you get 80% cpu (with a 400Mhz...), just to encode this crappy 64 kbps.
Yes exactly for all people having so many skipping problems check your cpu with taskmgr.
So you cannot play video with A2DP unless you have 1Ghz!!! good for battery life.
If you like music you want good earbuds. There's none with A2DP.
So what's the point again apart from having to charge one more device?

1: Well, I'm not sure on the bluetooth 2.0 specs, so If there is a spec limit on 64kbps, then this is new to me.
2: And the skippingproblem is not just connected to the CPU-usage.. But if you have some info on this issue, then please; do share it with us.
3: A2DP headset with minijack is available many places, even HTC has one. And if you take a look at DS970, you will see that it's the same as Sony MDR-series.
4: And well, the CPU usage is a issue, but that is the only part that I agree with you on..(but let us be frank, I've bought a pair of A2DP headset, so I do smell a bit "conflict of interests" here...)
And to the bottom line, I've bought the Trinity because it's one hell of a gadget, and so is bluetooth stereo So if anyone want to shoot me for that, well hell yeah, go ahead
Edit: And FYI meroupow: I do feel you are a bit rude in the way you wrote that response, or at least a bit arrogant when you post a comment like that. Trying to mock people who have bought A2DP headsets and are tweaking and fixing issues to make them work correct(this also goes for GPS on the phone, black coating comming off, improving camera quality, getting the ATI ImageOn to work correctly... etc) . And I must honestly say that yes, you do have some points there, but you should be able to present your views in a much more polite way...
Sound better but discontinuou. Impossible ear music. The sound goes on and off continuously. Why?. How can I do?
I am sorry if you felt I was being rude.
That was not my point and It was probably the wrong place to say what I said.
It is just that just like you I bought this A2DP stuff with my Wizard.
Just like you I tweaked it as much as I could and managed to get it work.
The problem is when it comes to sound quality is important and just working is not enough.
When you show your happiness because it's finally working, people think you are happy because it's good and they are buying it. And get disappointed too.
I just wanted to warn people on the fact that it's not working to watch movies because of cpu and that a 5$ earbud will have far superior sound quality.
It's just a toy and by no way a mature technology.
I've got a CB2530, hard to pair and I still don't know what do I do for the pairing to be successful, but I do manage to pair it after a few attempts, on the registry I just disable jointstereo, set the MaxSupportedBitPool to 320 and the quality is quite nice and with minimal skipping. High cpu usage of course, but if I set the MaxSupportedBitPool to 80 the quality is quite crappy and the device gets equally sluggish(gets worse when you touch on the screen, as K-Rally does even with the new ROM).
As for the pairing, I still haven't confirmed, but I think the registry setting that enables the bluesnarf option on BTCrawler has something to do with it(the bluetooth ISC mode thing), because right after setting it I managed to pair the headset right away, the thing is, I was also successful in other occasions when I hadn't set that reg. option.
Hearing the pairing sound from the trinity or headset doesn't indicate anything on my case, and I think I've already tried these reg settings you mention, but I'll try them again as soon as I get home to see if there's any difference and post the results.

Install the Widcomm BT stack. With that, you won't have complaints - neither have I.

Does anyone know what is changed when you DO pair with the button on the headphones? With some models, you MUST do it because, otherwise, the music will be muted after about a second (see http://forum.xda-developers.com/showthread.php?t=282008 for more info).
I've searched around in the Registry for changes, without any success. It's possible we could directly edit the headphone connection-dependent parameters set AFTER the headphone's initiating the connection to avoid sound problems. If we knew where they're stored, that is.

BTW: is it the profile and software on the phones/PDAs that arn't handling it, or is it the standard itself that sucks? (or in other words, should I keep my headset for later usage or return it to the store)
I use Plantronics 590a and the skipping problem appears very rarely, mainly when I use volume/track buttons on headset. However, yesterday I also connected the headset to a normal stereo (via the 3.5mm adapter) and noticed the same occasional skipping. So in my opinion the skipping issue problem might be from headset, not Trinity.
I also tried a Nokia stereo bluetooth headset and noticed serious skipping problems - unusable.
PS: there is indeed a skipping problem if I open/close other applications while listening to music. It looks like the processor is very busy - system very slow etc.
PPS: any suggestions for a player that has equalizer? WMP doesn't and the sound is not that great (especially when compared to my old SE P900 which had an excellent player - best I've heard so far... )

Hi all,
As always, someone has to have a different view of the issue. I got my trinity a couple of weeks ago and went and bought a Plantronics Pulsar 280 stereo headset. Mostly because of the stereo jack. I have not updated trinity nor have I applied any fixes, just paired right out of the box, as always from trinity BT manager. It really sounds great, particularlly the base is fantastic because of the earbud design. Even you may choose the actual headset of your dreams by using the standard 2.5mm jack. I have owned a "no brand" headset (still do) but it is not BT 2.0 and I think it makes a difference. The plantronics does not skip and it sounds great. Most of my MP3 is 128k and above so no limits with that. I have not checked my registry settings as they are default rom image set. I am using ROM 1.15.412.2 and Radio 1.20.00.11 (my trinity only speaks spanish for now, hope to change that soon).
Point being that the software and quality of the headphones makes all the difference, don't be so quick to blame trinity, just a piece of my mind. Keep it up guys!!!

hello after months of looking hard for the htc audio booster and pestering others in this forum i finally found the htc audio booster that actually works perfect on the htc athena and guess what its also in vga mode
below you will find 2 picture images of what it looks like and also the .cab file
the following things i noticed when using it is this ,,,when u pair a stereo bluetooth headset it doesnt work ,,,it only works when you use wired headphones either thru the 3.5mm or the mini usb port !
apart from that its all fine just wished they made it 10band eq would of been more serious for music listeners
please enjoy

Try TCPMP. There is equalizer which works with bluetooth stereo as well.
Can anyone recommend something that already works well with HTC Touch/Pro?
Does Motorola S9 work with WM6 BT stack for stereo?
There are no good a2dp stereo headsets because the equalizer only works with wired headsets.. Htc: please fix this.
im using the sony stereo bluetooth headset hbh-ds980. works fine.. the volume for the music and for the phone calls are the same key but the headset keeps them programmed differently. so its nice. the onyl thing i saw that sucks is that it doesn't bring a clip to attach the receiver to your clothes.. so if you doing a lot of moving then its going to fly up and what not.. so thats annoying.. i took the clip from the standard HTC headphones that came with the phone and put it on the bluetooth and just slightly attach it to my shirt.
I'm using a Motorola S9 and it works perfectly. No problems at all, all buttons do work. Sound quality is very good!
One more vote for hbh-ds980. Been using it with polaris, diamond and HD. The music quality is quite good and functionality including addressbook and last calls access works fine.
The Motorola s9 HD's are out and the seem to have improved quite a bit. I personally have the regular s9's and they work great.
oh yea.. sry forgot to add.. haha. you can go into the recent calls list and into the phone book quite easily.. and have multiple devices hooked up at one time and get calls from them all..
the only problem is that i get the phone number instead of the persons name when they are claling me.. does anyone know why? the names show up when in the phonebook and everything..
Ok so not bluetooth but i use my sennheiser PXC 450, noise reduction...cant imagine better sound on the move
Sony DR-BT21G
I found an equalizer that works. The internal one in coreplayer.. Now nokia bh-903 bluetooth headset have bass and nice sound.
Hey people. Thanks for all info, been reading about the defy here for some time. Got one now and I love it. I had a few smartphones before and this is by far the one I would stick to forever if I had to.
So, my question is: Are there any good head phones (in-ear plugs, with mic and maybe even music controlers) avaliable, and that I can be certain to be compatible with the Defy? Or could I just buy any that works fine with other Android or Motorola devices? Motorola is not sold in Sweden where I live, so it's not like I can check out any stores IRL here...
With my Xperia x20 mini, exacly what I described came along with the phone. Too bad that you just got these normal plugs with the defy. Cos there is just no way I would use those. As of now I stick to my old head phones but I'd love the mic function with my In-ear plugs.
Thanks for any help!
Ekholm
Ok, so I found this site:
thinkmotoroladefy.com/wiredheadsets.html
and it's all looking good, except for the part that they are a bit low-priced. I'm looking for high quality ones. I.e my current head phones was about 90 USD.
For information, iphone handsfree works fine
Thanks!
By chance, does anyone know if "Klipsch Image S4i" would work? they seams to be perfect! Volume, track fwd bwd and play...
I got one of these a few months ago, works fine with my HTC Desire. Not the best headphones in the world, but more than capable of handling a bus ride. You can unplug the headphones, clip on a small plastic hook and use it as an in-ear Bluetooth headset too. Two birds with one stone
I can get around 10 hours out of them between charges.
Thanks, it seams to be mono, right? Mono doesnt sound too thrilling...
If you use power amp you can set it up to use the controls on headphones to start and stop music, instead of calling the last number you called. It will work on the lock screen too.
This was the only way of getting it to work i found for the defy and i tried about 10 different headphones with in-line controls. Bluetooth stereo sets like the one above with controls seem to work fine for music however, ive got a sony bluetooth set and the controls worked right away on the standard media player.

I use Razer Moray+™ they have no remote function so you have to answer the call on the phone. But you have a mic and the work good for musik and phone calls.
anyone got an update for this, still looking for ear buds with a mic.
Klipsch Pro Media set(based on the S4i but a bit better build for traveling etc).
Awesome set up with defy. The S5i rugged set is also great as they are moisture proof and very overbuilt.

I wonder if Sony Ericsson's headsets work. These seem pretty good:

goo.gl/eQc9W
Would be good if they work.
BTW, I tried Samsung Galaxy SL's Stereo In ear handsfree and the sound quality was just awesome! Might get myself one of those!!
I've tried the iPhone standard headphones and sound works but Mic and controls don't. There is a pair of sennheiser mm50 Nokia. Which will work fine. Ordering one shortly.
Hi
I can confirm that at least not all iphone headset work the defy, even if the pinout is identical. I tried the Sennheiser MM70i and they don't work!
I soldered the mic of the standard Headset to the MM70 and now im happy,
but definitely nothing i can recommend

Hi guys
i read xda so much, but i don't write as well
i have a big issue with my galaxy s 2
i use a bt car stereo, with a2dp and avrcp support
i used to stream all my music collection from my iphone4
now i got my sgs2 and i love it... but
the audio stream looks "limited"
it seems a bandwidth issue, or i don't know a quality issue
with iphone4 i streamed at full quality, now the sgs2 sounds a lot worst
other than that, i have to disable wifi because if on, the music is choppy and skips a lot
with wifi off, the stream goes well, but it sound bad...
sorry for my not so perfect english... i hope there is a way to improve sound quality because i "live" with a2dp on in my car...
That's strange. My a2dp stream actually sound better from sgs2 than it does from my ipod touch 2nd gen, iphone or my computer (bluez).
Receiver is a belkin stereo a2dp receiver.
Are you sure that it's not in handsfree mode? Long press the a2dp device in bluetooth settings and there should be an option to select it to be a media device, make sure it's checked.
thanks for the reply gvoima, no it's in media device mode
i think the problem is the bitpool
i've got the same problem of this guy: http://forum.xda-developers.com/showthread.php?t=708685

I got a belkin stereo receiver as well, but it sounds bad and choppy, just like the topic starter described. Though still compressed (this is a known issue for A2DP due to bandwidth limitations) songs sounds much better from my Nokia E52 work phone.

The "but my (insert phone) worked better" isn't really valid. For as many people who make that statement there are an equal number who are shocked that the SGS2 works where other phones haven't. This is kind of like the Wi-Fi issue. When two pieces of equipment don't interact well you can't just blame one of them.
In my car and on my Yamaha YSP-4000 the SGS2's Bluetooth works better than any phone I've used. That includes the HD2, G2, and G2X. The sound is much more defined and headset controls (random and repeat) show available for the first time. The SGS2 also feeds track info to the car which none of the others did.
Bluetooth connections and sound quality are always a big YMMV.
My Sony MW600 sound great, I use to have a Motorola Defy , and it use to have an "Enhanced Stereo" option in the blue-tooth menu, the Samsung S2 does not have this option.
@BarryH,
Oh I know, I not blaming the SGS2. I only think the SGS2 out sound to it's output module which is somehow less suitable for the kind of compression, maybe set by the Belkin module. Actually I'm currious if there would be ways to change the way the SGS2 sends sound signals via A2DP

LG's implementation of Bluetooth drove G2X owners crazy. Check out this thread from the G2X forum...
http://forum.xda-developers.com/showthread.php?t=1117769
Maybe it will help. The only other solution for the G2X was installing an AOSP ROM.
Well, I tried it (Bluetooth Fix Repair), but off-course that tool is for a problem the SGS2 does not have.
From the tinkering I've done now I know.
- Having MusicFX installed does not make a difference
- Video players running ffmpeg codec do also not make much difference in sound quality
- The -type- of file does make a difference, i.e. low bitrate files play better
This makes me think, is there a music program which can resample/recode music before playing. I'd rather have software do that than A2DP do it badly, or is mono output (other than all the tools enabling playback on mono headsets which is for pre-A2DP headsets and thus something else) possible?
Edit /system/etc/bluetooth/audio.conf
Uncomment "Master" option and set it to "True".
Uncomment "MaxConnections" and set it to 3.
Most Android devices have this file configured poorly by default, those 2 settings should help though.
I'd suggest also enabling HFP and AutoConnect.
Great! That definitly reduced creaking/noises and even the occasional stuttering music!
Since you seem to know your stuff, would there be a way to send a mono signal to (only) the A2DP stack and would this decrease the 'tin can' effect? I'd rather have better upper tones than stereo.

Thanks for the suggestions...going to try this and see if the sound quality improves in my car stereo.
Till now the best A2dp sound quality was on my Nexus S, but that was with the help of custom rom development and vodoo sound. Worst was the g2x.

Ok guys, I think I might have... accidentily... run into a phenonemon.
I tested my phone on a Creative D100 wireless speaker it it went great, no tin can sound, no hickups.
This proved to me that there had to be something wrong. Now when I was posting here earlier I was listening a lot to music and at a certain moment I thought... wait I'm not hearing a tin-can sound anymore. However, later on while testing I heard it again so I thought I imagined it.
Powering off the phone and powering on again I was able to create this again. No tin can sound... however a lot of hickups (as if a lot of data had to be sent and it didn't quite fit). I made a call to my work phone (sound on the handset) to test and then the tin can sound was there again, no hick ups anymore though. Strangely enough a haven't been able to replicate the 'no tin can sound but hickup situation' though by powering off and on again. Tried after playing on the Belkin on the D100 again and no problems at all, great sound and no hickups whatsoever.
It appears to be a bigger issue with android connected to the bitpool setting the bluetooth receiver desires...

Let's hope the upcoming Cynogen can fix this issue.
I too felt that the A2DP sound quality on the Nokia BH103 is crap as compared to my Nokia 5800 (sounded even better than stock wired headset). It also uses a lot more battery, I find mediaserver using a lot of battery.
How do we escalate this to Samsung?
