Htc hd2 sound quality

When I talk on this phone, the sound is very poor... Although not too loud (like other complaints) but the sound crackles at high frequencies... The speakerphone is even worse...
Is anyone aware of some tweaks to improve communication sound on this phone?
Can AudioBooster be set up to work with the phone's sound not only the music player? Any other options ???
Thank you in advance.

I think the high volume on this phone is artificially boosted over what it's meant to be, i.e. HTC have modified the audiopara (or something like that) in the Windows folder to try and boost the speakers sound over what it's meant to be.
(Something that ROM coookers figured out on the Diamond I think).
I think, maybe someone can reduce those values back to normal? The speaker will be a little quieter, but it won't crackle or distort as much.

Which radio do you recommend? I have Leo_RADIO_2.07.50.27_2 and a terrible sound while on the phone.
Sound is to loud, impossible to lower volume enough. Much distortion even at lowest volume (which still is to loud). Bad sound in cable handsfree and BT handsfree.
Soundquality while playing music on the other hand is perfect in speaker, handsfree and BT handsfree.
Suggestions?

Since sound is often a pretty subjective matter, so I'd like to interject that the phone network only transmits from around 300 Hz to 3,000 Hz. Therefore the sound of a voice over your phone will never sound as clear and nice as it should, let alone like the 192 kbps-MP3-file you are playing
If it's worse compared to other phones however it's, as stated above, likely a problem with the radio. I use the 2.08.50.08_2 from [REF]The HTC HD2 Radio ROM Thread and have a quite decent quality.

I agree totally - if it sounds good or bad is individually. But, the sound quality in my HD2 is far worse than in my 5 years old SonyEricsson, and when I borrowed a Nokia the other day I was surprised how good (clear, crisp, distorsion free) a cell phone can sound.
I have a lot of distorsion and all too loud sound. Often I have to hold my phone 20 cm away from my ear just to avoid getting half deaf..
Thanks for the tip, I'll try the 2.08.50.08_2 Radio and hope for a better sound

you can try this hotfix...worked very well @my hd2
i got this from another forum.
little info: some users said that the soundlevel is now always set up to 100%...but try it on your own!

Thanks, trying it now, will report back after tomorrow's hardcore testing at work..

Return it if you can...
I had Nokia E71 before and it's speaker is fo another level better than HD2... BUT, question is: when I'm gonna use speakerphone on my HD2? ... almost never

Seems better, but a little to subjective at the moment. Will keep trying and report back!

Definitely better after the patch. Quite good actually. I have not seen any side effects yet, only clear sound, and better volume.
Thanks for the hotfix!
Will try it on my colleague's phone also now.

sound quality
I used the hotfix as well but it appears to have made no difference whatsoever to the quality of sound during calls , so my phone is going back to htc again and if it returns with the same issues i will ask for a replacement as due to the ammoun of posts on here this is a major flaw in the phone and a highly irritating one too , i love this phone but the audio quality during calls is appalling in comparison to all my previous phones .

After a couple more days of testing I found out that the patch gave no effect at all. BUT: I found out another thing: Even though the system volume is at lowest according to the meter, if you increase, you actually lower the volume. So, if you during a call first increase and then decrease the volume, it gets acceptable. Still to loud though.
So, it seems like what HTC really should do is to get the dialer use the sound mixer properly. Today it is obviously oversteering which creates distorsion.

this is a war we won't win

I've bought my HD2 back in Dec the 11th and since then I've been in contact with HTC about fixing this problem. They've given me a debug tool to run on my device, sent the logs twice and so far they've done nothing about it. I've given up. What I do for outgoing calls, while it rings I turn the volume all the way up and then all the way down before the other party answers. doing this you get a decent sound. Can't do much about the incoming calls,
As far as flashing different radios and roms... I've flashed about 30time already. tried all the possible radio/rom combinations but with only slight different results. Nothing to brag about!
the fix I attached helps a little bit!
If anybody finds and cure let us all know! please!!!!!

Earpiece volume

I just got it and noticed the earpiece volume is still low even with the volume turned all the way up.
Is there a setting I missed or maybe a registry fix?
Any help would be appreciated
HTC HD2
OS 5.2
MANILLA 2.5.2
ROM 2.13
RADIO 2.10

Don't mean to offend you. I had the same issue but was more of a user issue. I kept increasing the volume not paying attention that I was adjusting the ring volume and not the system volume.

if that doesnt work you may need to return it. My friends HD2 had low speaker volume and low earpiece volume. As much as we tried, we couldn't get it to go.

N1M1TZ - No offense taken, I only adjusted the volume during a call and at max it is still quiet.
I checked the settings/sounds, no adjustment for the earpiece just the ringer and the system sounds.
marduk79 - after doing a little digging I have found that this is a common problem with this particular batch of phones.
The first batch came out and the volume was set way to high that it was actually blowing out the earpiece.
I think I may have found a solution, if it works I will post it.
Thanks for the assist.

So what is the solution... My first one had sweet loud ear piece volume. But alas, the speaker blew. My replacement is alright, but I want it to be a tad bit higher... Lots of years of loud punk rock have made me slightly def I think...

Anyone know if there is a cab or registry tweak or something that will make the volume louder in the ear piece speaker?

How low? Like so low you couldn't hear it, or just low enough to be annoying? Basically my first HD2 was nice and loud. The new one is about 3 bars lower sounding turned all the way up... Which annoys me because I know the other one was louder and it's hard to hear people if I'm in an environment with a lot of background noise.
I feel like if I tried to take it in to get a replacement they would think I was nuts.

headphone and phone speaker too low
I too beleive the headphone volume is way too low, when listening to music or taking a call on the headphones it is barely loud enough too hear if there is any background noise such as traffic or conversations going on nearby. I have the volume about 75% when listening to talk radio stations, on my headset, no background noise present and it is at normal listening level. So if there is background noise, I need 100% for it to be loud enough to hear clearly. The phone speaker is not much better, when listening to calls on speakerphone the percentages are about the same for equvilent listening circumstances. I have tried "AudioPara3 TMO" and notice little or no difference in sound. Does anyone know of anything that will increase the maximum volume level for both speakerphone and headphones?

I'd like to know if there is any registry hack to increase the line out volume as well. My line out volume is very low, I have to put it to about 50 percent to match what would be the 20-30 percent level of my old HTC Touch (Touch 1 to HD2 - quite an upgrade, eh?? )

Volume hack possible?

I know on some other Android phone's (e.g. G1 http://androidcommunity.com/forums/f4/volume-increase-hack-found-18107/), a software modification has allowed for much higher volume.
Not sure if actually increases the speaker volume as well, or just through headphones?

+1 for the speaker!

Agree! The speaker is WAY too low!!!
/CK

+1 here too

It would be nice, the speaker is crazy quiet.

i wonder wot the reason was for them to keep it at that level of sound and is way to queit

Or it possible use the front speaker for avi/video/streaming?
Sent from my Desire HD using XDA App

It seems everyone has the low volume speakers.
I noticed that Angry Birds seems to be a little bit louder than other things.
Anyway, I highly urge everyone that thinks this is a problem to give this feedback to the HTC customer support. Obviously this is the only way to get an official fix for this quicker, if at all.

Wonder if the speaker can handle a increase in max volume.
Anyway, aren't there hidden service menus on the Desire HD that can be triggered with a phone code? In the service menus of a phone there are always some nice parameters to tweak.
I tried some general codes, but none of them seems to work (except the *#*#INFO#*#* of course, but that's a general hidden android menu... even works on the emulator)

until we get access to the rom via Bootloader, there is no general tweak we can do.
However, just for music, try PowerAmp from the market. It has a great pre-amp setting to boost the volume (be careful not to blow your speakers though)

We want increasement in the general speaker volume... Not just music

You can do that, but you will need a script to do that at every launch, since /system write is not permanent.
Furthermore, after each time you adb push the files, you need to restart mediaserver in order pull in the new settings.
Last but not least, you will need to modify the DHD audiopara, since the G2 might not work well.

To make the long story short... SPAM HTC's EMAIL!!
WE DIDNT BUY THA F*CKING PHONE FOR THIS ISSUES ...
And they thought they could fool us ... with their Dolby and SRS enhancements!
Disguzting!!

I experienced the same, missing calls because the damn volume is just too low!
Also, when you use the speakers when having a phone call, you can't even hear the person unless you're in an absolutely quiet room... The same goes for music, youtube, navigation..... Anything!!!??!?

I returned mine because of the low speaker volume. I was missing 99% of calls because I couldn't hear the phone ringing. In my business I just can't afford to miss calls. As I sold my normal desire to get this phone I had to buy an Orange San Francisco to use till something else comes along.
I was playing with a friend's Nokia N8 & have to say the speaker quality & loundness is outstanding on it. Also used as a phone its much better than the DHD. Shame the OS is a bit dodgy.

speaker
I am not sure if you are speaking about speakers of DHD in general or just about external. Well, Ive sent back my DHD to Vodafone because call speaker was so useless that I could not even hear other person when I had TV on. Hopefully it was just one bad piece but its apparent that HTC fcked up DHD with poor quality speakers in general. I am waiting for my phone replacement and even when I know that it would be hard to say DHD goodbye I am afraid Ill have to if speaker quality will be that bad again

Why don't we use this... compile libaudioflinger and DSP Manager, in which we can set presets (you can +10 every channel of sound, so it comes out 10x louder).
Good luck compiling... I couldn't find an example
http://github.com/CyanogenMod/android_frameworks_base <-- libaudioflinger is in /libs/ (yes it's default in Cyanogenmod)
http://github.com/CyanogenMod/android_packages_apps_DSPManager DSP Manager android application, yes everyone should be able to compile this one

[Q] Earphones Mic too low volume

From Day one i have been trying to get good earphones with Mic for nexus 4
tested out more than 6-7 quality earphones with mic like J6M, Klipsh, etc
but the microphone volume on the other end of call is too less compared to apple ear phones( recently switched from iphone)
I have to keep the mic piece really close to my mouth for a good conversation...
can someone help me here.. the mic on nexus 4 works perfect but when i connect earphones the problem begins... i used mic sensitivity apps to test and they pick very less volume from the connected mic
How do i boost the mic sensitivity on earphones or should i return the phone

Will try with my skullcandy's and revert

I'm having the exact same problem - did you find a fix?

I tried quite a few.. expensive as well as cheap ones. finally i got hold of a cheap ear phone set and the volume to the other end is good to be heard (as I have been reported).. While trying them all, I was calling my friend and asking him.. so thats how I know i picked the best one. However, since it extremely loud.. i kinda have to keep it away from my ear a bit and volume on phone is turned down to minimum.. Plus, due to its sheer loudness, I can hear the buzzing sound.. For the first time i noticed it, i.e.: through these extreme loud ear phones. The other party hears it too. Never heard it while on call directly using the ear piece. Strange.

Do you mind me asking which brand headphones you are referring too here? I have the same issue.

I bought from a local shop. It was a knock off of beats audio. The sounds it throws is EXTREMELY loud.

Is it just me, or does the OP make very little sense? I'm completely lost at what he's trying to ask.. Something about the mic? or the sound output of the "earbuds"?
No trouble here with any of the wired earbud sets I've tried. Clear as a bell and no buzzing.
If its so Loud for you, what are you not adjusting the volume? Would kinda of make sense to do so...
Or you could upgrade in your tech and get a bluetooth earbud.. I have absolutely no problem with volume levels from my Jawbone; I'm hear clearly and I can hear them just find (even when driving with all windows down, it sounds like they are right next to me yelling)

Nope, it's you. OP was referring to the mic volume on the headset being low, but in filthykids response, he mentioned that the headphones that solved the quiet mic is also very loud on the earpieces.
Also having the same problem, BTW.

[Q] Earpiece distortion

HI there guys.
Brand new to this forum.
I've searched for days and I'm unable to find a solution.
I'm experiencing a crackling or a distortion on phone calls at certain volumes. I noticed it with certain pitches in peoples voices it would cause a vibration in the ear speaker and some distortion in the sound. Kind of like the speaker is being over driven or has too much power going to it. It usually goes away if I turn the volume almost all the way down, but this is obviously not a practical option since I'm not always making phone calls in a dead silent room. The speaker phone works fine. This only happens when I'm using the earpiece. Is this normal? Is it related to the camera autofocus sensor rattle? Are the sound vibrations from a person's voice enough to set off the rattle? It's really annoying as I tend to make phone calls a lot and I don't like using speaker phone or a headset. Does anyone else have this problem?
From what I can tell, it happened and was normal in the S4. (http://forum.xda-developers.com/showthread.php?t=2280930).
Please help. Im deciding if i need to return it.

..

It's too bad that you didn't describe it in more detail.. i.e. give us steps to replicate it. A recording of the distortion would have been helpful too. I haven't noticed what you describe but it sounds like the gain or auto gain is too high and your earpiece speaker is being overdriven.
There is a gain setting in the service mode menu but first you need to distinguish an app issue or possibly damaged speaker before messing around in the hidden settings. See if you can find an audio app that will give you a wider adjustment range for your system volume and gain.,

Thank you for the reply.
If you go into the service menu, the go into the low frequency test. At 100hz and 200 hz there is a little bit of buzz in the headset reciever unless you really push it against your face (which i assume kind of tightens the spaces in the plastic and prevents whatever vibration in the speaker is occuring).
Hmm.. the vibration is akin to as if you were speaking into some cellophane wrap; like some film (maybe for waterproofing) is covering the speaker.

Oh. It's also worth noting that I cannot replicate the issue on Skype or Viber. Those sound crystal clear.

Bump. Anyone?
