[Q] Mono output through 3.5mm headphones? - Android Software Development

hi all
I know you can buy adapters for 3.5mm headphones to combine the left and right stereo into a combined mono output for both ear buds.
...surely, there must be some software for Android that can do this for me without an adapter? Work are happy for me to listen to music but require me to keep an ear free to hear colleague questions or calls - but with one headphone, I lose half the stereo.
Anyway of making both channels go into one - without the need for an adapter?

It seems to be a known issue. I agree that the accessibility options in Android are lacking and i hope you get this soon.

Thanks for the link mate; I trawled Google before posting this as I couldn't find an answer anywhere. Evidently, I didn't look hard enough.
I've sent an email to the creators of PowerAMP for Android; apparently their next release will have a balance feature and it'd be nice if they solved the problem with a 'mono' button too...

An option would be to use a bluetooth headset and if your phone is a2dp then download one of the mono bluetooth apps from the market to use it to stream music.
Understand you asked for the wired but not everyone is aware of the other options they may have.

Mono Bluetooth for music

I am currently running Dudes 1.1 cupcake right now and loving every
part of it except that I can't seem to listen to my music via mono bluetooth. I have a few regular bluetooths for talking and would like to listen to my music thru them also. I read about stereo bluetooth working and all, but does it not work on mono bluetooth.
Please help..
Also, if I must get a stereo bluetooth, can you suggest were to go to get a cheap good one that will work. Thanks
bluetooth music help
someone really needs to help please.. Stuck using a standard MP3 player with CORDED headphones. .. Please guide me to getting bluetooth mono/stereo on my DUDE'S CUPCAKE ...
i wish i could get this to work as well, i have a phenominal bluetooth headset (mono) and am allowed to wear it around at work all day (but no stereo headphones) since its a product we sell, and would love to be able to listen to my mp3's aswell
Previously used a blackberry pearl with crackberry software to run MONO BLUETOOTH for my music. Now I lost that with G1. I LOVE my G1, so don't get me wrong. I just wish they had something to offer mono bluetooth music. If they did, I swear it would be perfect thanks to DUDES Cupcake.
Yep, i would like to know this to. I know it can be done because you can force the sound after the call for like 10 to 20 seconds then it goes out.

I could but I like my Motorola H690

I am caving in.. I will buy a Stereo Bluetooth headset, if i am guarenteed it will work on DUDE's CUPCAKE 1.1a .. I see on the comparision chart that it doesn't support stereo bluetooth for music.. Can someone please confirm or deny this..
If confirmed, what is the cheapest bluetooth i can buy that will play my music.
If DUDE's doesnt support, what can you recommend to install to work Stereo/Mono bluetooth. I was leaning towards jf 1.51, but i would love to keep DUDE's
Thanks again
Dudes build will work with stereo bluetooth because my car's head unit will accept it and works great just not with my mono motorola headset.
Hate to bring up a older thread but I am wondering if anyone has found a way to do this. I dont want to buy a a new bluetooth because i have no use for them. Any help would be greatly appreciated.
^Bump. I would like to know as well.
When I pair my phone with the Bluetooth (Plantronics 925) and select options - I see it connected to phone audio and media audio. But when I play music (stock player), it plays through the speakers. I did try a Google search on this, but not seeing a solution to it

BT Audio for Android

Ok, I'm looking for some way to route the audio of my Magic to a mono BT headset. I have been searching the threads and Google for days now and unless I'm blind (come to think of it I've been called this before) I can't find any app for this purpose. I had a program called BT Audio for my WM phone that worked like a charm. Anyone got any ideas or up for the challenge to making an app let me know?
Android 1.5 introduced A2DP support, so all you should need to do is pair the device and fire up the music app (might be a couple more settings in between, but AFAIK it's a simple pairing job). So I'm wondering if your headset doesn't support A2DP and that WinMo app was channeling audio through the regular headset profile.

Your right my headset doesn't support A2DP (It's cheep ). I know it is possible though, cause sometimes when I am using an app or game with audio and someone calls in I hear the audio through the BT headset for a sec before the phone connects.
WinMo had a few different apps for this so I'm surprised that I haven't been able to find anything for android yet. I didn't think it would be that hard to do.
It could be that its built in to the ROM that I have and I just haven't found the settings for it yet. I'm using the My Hero ROM. If anyone knows Let me know.
Hi!
Once you pair your device (on my Cyan ROM anyway...) you can go into the BT settings, long select the device you just paired with, choose options and if it supports X feature on the BT profile (in this case, audio) then there will be a check box that you can click to enable that function/feature.
Other than that, you might have some luck searching the Market for an app similar to BT Audio. I used to have a Shadow and I know exactly what app you are talking about, all in all though I was less than impressed with the meager selection of apps I had available compared to what I have now; and definitely even the out-of-box experience is light years ahead of any WM experience. What I ended up doing instead was just grabbed a new Stereo BT headset and problem was solved There was one on http://www.woot.com a little while ago that I'm loving (LG BT250 I think?).
Good luck!

ive also been looking for this, cant find it either though

I wish I could . I didn't mean the one I have was cheap in the way of money cause it cost me $80. Cheap in that it was the cheapest of the headsets that I could get with voice recognition built in as I work and drive around a lot of noise. I didn't want to pay the $130 for the good one.
I wonder if there is anyone with the right skills out there that can write a app like this. hint hint.
I do appreciate all the work that goes into making these cool app that I use every day so if nothing shows up, I guess I'll have to live without.
Thanks guys!

Dunno, I think they just want to advertise the site in their sig...
I have a stereo Bluetooth headset (Plantronics 855) that works great with the Droid; however, there are times when I want to sent A2DP to my Jawbone Prime, which is not A2DP compatible. The profile only shows phone audio when selecting the device in the Android BT manager. What needs to happen to transmit full audio to a non-A2DP headset is enabling SCO (Synchronous Connection-Oriented) connection. I have searched everywhere I cannot find a software gateway that enables this feature in the Droid. There is an app in the market called Sound Route Switcher that claims to enable this but then blames Android for is application not working with Bluetooth.
I will keep looking and post anything that I find but I am stumped to this point.
Thanks dbigdawg
There's a little Greek in there for me, but I appreciate the effort and I'm sure many others will too. Look forward to what you can find.
Hate to bring back an OLD thread, but has there been a solution found?
Last I looked was back in April.........................Nothing
But like I said before I have been known to be blind to anything past the end of my nose!
I really miss being able to listen to music all day and not have on headphones.
Thanks for the reply bud. Maybe with some luck I can see if I can find that old file I had that was supposed to work, but didn't on 1.5. Now that I use 2.1, it might be a different situation. If I can locate it I'll post it here.
Hi, there is a new app named "Super BT Mono" which could route audio to bluetooth mono earpiece. It might be what you are looking for.
Thanks
Thanks for the info. That Super BT Mono did the trick for me.

HTC Headphones Mod, or something...

.
Hi, first of all, I did this thread here because I'm not quite asking about the accessories, but about a modification. But if any Moderator thinks this should be moved, please do so.
At any rate, the thing is, I'm still beaten up about the fact that the headphones bundled to the cellphone are such low quality. Ok, there are some superb phones that comes with crappy headset, but you can replace them with any other headphones you have. But this one doesn't support detaching them. That's low quality for me.
So, I went to search for detachable HTC headsets. To my wonder - or bad searching skills - I found none. All are just one-piece headset. Really?
Ok, maybe makes sense when we take into account the fact that for an odd reason, HTC headsets works different than the rest. Just incompatible with other phones.
And here is my question. Is it possible to mod this headphones? My idea is to just trim the original bundled and re-wire the plug to some kind of 4 bands 3,5 female plug, so I can connect non HTC heaphones with mic to this sort of adapter and that could operate the phone.
Or, maybe there's such adapter out there in the world? theory says I'm not the first one to think in this, but I've found nothing so far.
In resume:
a) Are there detachable HTC headsets out there?
b) Is it possible to make an adapter for non HTC headsets?
c) Does this adapter exits already and I'm just wasting time and not money?
bonus) Is there some sort of schematics about HTC headsets? I just can't guess why others are incompatible, but a different wiring...
Many thanks before hand!
.
Really? no one? :/ I cant believe everyone is just satisfied using that lousy headset or just headphones with no mic.
why bother. Any set of decent cell phone headphones work great.
I got a pair of rocket fish headphones. It comes with a mic, and a voice dial/answer button that works great on the Aria.
edit: here is a newer version of what i have.

Don't use headphones here, I have bluetooth in my car .
But, I'd suggest buying skull candy headphones, or even the headphones that come with some nokia xpressmusic phones are awesome. (particularly 5800).
i use these skullcandies because i mainly listen to music on my phone they have a mic on them to so i kan use the on a call if i get one while i have them on
I found that if you download a music player with an equalizer built in, you can improve the quality of the sound 100%

[Q] Bluetooth Headset Audio?

Hi All,
I have a 16GB TF .. and it's been very good so far. However, I'm having an issue that I think is probably simple .. but google & xda searches don't find anyone else with the same issue.
I want to use Skype over the tablet, but with a bluetooth headset. Using the TF with just the internal mic & speakers is pretty speakerphon-ish .. and I'd like to use a headset.
I have a couple of BT headsets (one of them 2.1 w/ EDR), and I can pair any / all of them to the TF. Problem is, the audio doesn't come through over the head set, and I don't know how to force it to.
The TF (now running 3.1) acknowledges that the headset is connected (to phone audio it says) .. but the only options in the configuration is to remove it.
What am I missing? I see reviews all over the place where folks are using the tablet to play movies in the car, and piping the audio out via BT? I think I must be missing a config step .. but can't find it.
Thanks for your help.
Im kind of in the same boat but I dont think honeycomb has a "phone audio" functionality. Only "media audio," which is what you would use when piping audio to external speakers.
its the same on the phone, those headsets only connect to mono phone audio so if I was playing a movie or music its silent. So for right now I think you are stuck until they figure out how to make specific apps recognize the phone audio device.
Makes some sense .. so it knows there's a "phone audio" aspect to things out there, but we don't have any way to force the Skype audio to be phone audio and not media.
So if I had a stereo headset, would the system work with it and pipe the audio out since it would recognize it as a media audio system?
Where does the mic fit in all of this?
I have a BT combination headset/headphones which I paired with the Transformer, and from testing it I can say the following:
1. The transformer paris with the device and recognizes both the "handsfree" and "media" profiles that the headphones support.
2. The "media" profile (also called A2DP, stereo bluetooth, etc) works fine. I have listened to music in stereo though them and all of the controls like play/pause and previous/next work properly. If you want to listen to movies, music, or whatever else you should be fine.
3. I can hear Skype through the headphones, but testing revealed that Skype is using the Transformer's build in microphone rather than the one in my headphoens. It also doesn't respond to the call button. Thus, it seems to be using the "media" profile to deliver sound.
So, even though the Transformer can clearly recognize handsfree profile, it either isn't passing it to apps or Skype isn't asking for it.
It looks like as long as you plan to be Skyping with the tablet infront of you, you can get almost the same functionality of a handsfree/headset by using a BT headphones instead. As long as you don't plan to leave the tablet in one room and talk in another you should be fine.
hey so i tried Super BT Mono Free Trial and it actually worked. thought it was Froyo only and reportedly broken with gingerbread.
using Samsung WEP450 paired "handsfree" profile, turned on Super BT Mono and to my surprise audio from music player routed to the BT headset. sound is crappy, and so far can't get audio from BeyondPod to the BT headset.
rooted 8.4.4.11 with netformer 1.5 OC 1.6 ghz and juwe11 ram profile.
...
try jabra... coz jabra headset supports a2dp i had the same issues until i bought a jabra

[Q] Is it possible to have audio through both speaker and headphones?

I know that software can choose between speaker and headset even when the headset is plugged in (since the FM radio can do that). But is it possible to force audio out of both the headset and the phone speaker? I ask because I have an audio docking that I'm going to use in the car, and if this is impossible, I'll have to put up an extra speaker and amp for when I listen to the radio but want TomTom to warn mea bout those pesky speed cameras... So is it possible with a sneaky trick to choose both headset and speaker?
That can only be done over at the kernel's and the framework's side. The best bet is to customize the kernel. Detection of the headset plugging/unplugging is done by kernel’s switch driver and the event is sent to 'HeadsetObserver.java' which broadcasts the intent 'Intent.ACTION_HEADSET_PLUG' with information about state as plugged/unplugged. This is received by 'PhoneApps.java' and the audiomanagerr is informed to turn on/off the speaker which further passes the information to Libaudio.so (AudioHardware.cpp). These information is passed to the kernel to switch between the speakerphone and Headset. This might differ with Android 2.3, but forcing the kernel to play sound to both the headset and the speaker might be the only way. The first few actions are done by the framework itself. You can try or suggest this feature to the CM team. I know this is not what you want, but for the time being, you can perhaps use a dual audio jack splitter and connect your headset and a speaker. Alternatively, there a few apps in the market which enables live streaming on your PC over Wi-Fi. You can try streaming the media so that the audi is played by the PC and the connected speakers. At the same time, you can plug in your headset. This should work, but no guarantees...hope this helps, and i have to say that it will be an awesome feature if the devs can find a way to cook this feature into a stable android build!
Android? Yuck! Good on tablets, totally hopeless on phones! Was going to use my brother's Desire for on day, begged him to give me back something that actually worked efficiently after two hours! No, I'm talking about good old Windows Mobile 6.5 here. Didn't really think I'd have to specify that in a thread about general HD2...
While it might be possible, I doubt anyone will do it.
however, you can get audio through both headphones and external speakers using a special jack. it has a male part on one side and two female parts on the other.
of course. I've used the jack splitter on several things (I do a lot of work with custom installation of computers as whole house media servers). And that's what I meant in the first post when I wrote "if this is impossible, I'll have to put up an extra speaker and amp for when I listen to the radio but want TomTom to warn mea bout those pesky speed cameras."
But I have found sort of a solution: Start the HD2's FM radio, switch that to playback through the speaker (which is why I know this not only might be possible, but is possible with software, since the FM radio can play through the speaker even with a 3.5 mm jack plugged in) and mute the radio. Then all sound will come through the speaker. Kind of a pain in the ass to do it that way. I have found a Mort script that does it, with a few modifications, but I haven't had the time to check that out yet.
that's a weird workaround XD
I'll try it later.
Yeah, weird all right. Actually it's been used before. Found it on Google, with a reference to this thread: http://forum.xda-developers.com/showthread.php?t=444581 Another phone, same method.
