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!!!!!

Crackling in voice calls

I know that other posts on this topic exist, but I've done a bit of digging and believe the problem doesn't lie with the speakers, so hence, new post. Sorry it's so long...
I've had my HD2 a week now and have noticed the same problem as some others here (it's the crackling during calls, it's driving me nuts, even on the lowest volume setting). But something about the "quality" of the distortion got me thinking (ie it didn't sound quite like what I would expect from a speaker taken beyond its capabilities).
I therefore tried a few different things to try and see where the problem was:
First I needed to identify if this was source related, therefore I tried playing different things through the earpiece. I downloaded audioroute from xda (I forget where) and tried routing all sorts of things through the earpiece. I tried music, skype, video and normal voice calls and the only one that caused crackling appeared to be the normal voice calls. I made sure my sources were loud enough to rival the loud calls, but no matter how hard I tried, it was only the calls that caused crackling (at least the type that was p****** me off)!
Next I tried to see if it mattered which output I routed the sound through. I tried the earpiece, the back speaker and the headphone jack (with both the supplied headphones and some good quality Sennheisers). Again, I found that all sources, other than the normal voice calls, were fine. What surprised me though, was that the normal voice calls taken through the headphones crackled too (not just through the earpiece and back speaker).
Finally, I tried to determine the effect of volume on the crackling. To my surprise, I found that with my Sennheisers, the crackling did not appear to get worse with increasing volume. I chose the Sennheisers here because they could handle volumes way in excess of what the phone could produce.
These tests lead me to conclude that the audio path including the amplifier and speakers in the phone, may not be to blame. I also believe the problem is voice call specific. My understanding of what happens to a normal voice signal is somewhat limited, but here's what I think. I reckon the digital signal processing in the decoder for the phone signal may be to blame, as it has to pass through this BEFORE moving through the rest of the audio path (the volume independence was the clincher). This does provide some hope of a fix though, since the decoder is probably in software so can be modified. I'm thinking radio ROM here though, so not something we can hope to mod ourselves.
Anyway, sorry for the long post, if you're still with me, what do you think? Am I talking a load of bull. Can any of you replicate what I've found?

Interesting post, I have the same issue with my HD 2, definitely gone backwards from my previous phone which was an N95, I'm always adjusting the volume to reduce the distorted crackle when talking to people, the speaker phone is borderline crap as well, at least with the N95 you can actually hear a little bass.

when you say crackling do you mean like the person talkin on the other line says your voice gets messed up ? because this has been a problem with my hd2 since i baught it...about 1 month ago and im running 1.66 latest official WWE rom....

I had this problem with my first HD2 and also with two replacements phones from my provider T-Mobile in the UK. These phones were running ROM 1.43.
I have found the problem is completely fixed (on the same handset), by updating to the new 1.66 ROM.
I didnt really understand how to flash my phone with a new ROM despite reading a few posts. However, after following the thread (The Complete HSPL Video Guide - 621930 - in the HD2 ROM Development forum), I realised it was very easy, and had successfully flashed to the new ROM within an hour.

I have had and still have this problem. I havecontacted HTC, flashed different ROMs, and have had a replacement but the problem still persists. I am learning to live with it as the good out weigh the bad.

Thanks for all who have replied so far. I like the phone too and don't intend to change to any other, but may consider sending it back for repair. I also have a rattle (not the volume switch though, this is coming from near the rear speaker, this definitely doesn't seem right). I run the 1.66 WWE official ROM and it hasn't fixed the problem for me when I moved from 1.48 which it shipped with.

Help! No sound from speakers

Hi guys,
I have Tmobile HD2 and it's on stock radio 2.08. I flash nrg rom 04/23 6.5.x and everything was working fine. Today I just changed the rom to 4/23 6.5 and now my speaker don't make any sounds. Everything play fine through headphone but not from speaker. I play music, movies, ringtones nothing works. No sounds. I just did task29 and flashed to 2 other different roms and still no sounds. What happened to my phone? Is the speaker gone for good? I only had this phone for a week. Any helps is appreciated.

I've had a similar issue in past phones, where after removing audio jack the phone still thinks it is plugged in and even a hardreset didnt fix it. Try to remove and insert the audio jack rapidly in succession, its worth a try. Good luck.
Regards
Flashmore

Thanks for prompt reply. I tried multiple time with no success.

what other roms have you tried. i am running the energy ROM on my tmobile HD2 without a problem i would try it

I don't think it's rom related. I try nrg, miri, stock and cell. none works.

I had the same issue. I think thats happen after i use earfone.
Do you solve this problem?
thx

I had the same issue. The easiest way to tell if it is the same issue is to look to see if you have the headset icon in the bar when you dont have any connected. I solved this by (not suggesting you do it unless you are sure) there is a pressure prong on the top of the 3.5 jack. I used a tool to bend it down a little. If you still can I would swap it out for a new one.

i have the same issuse, and i've tried 2 rom until now.
in a call, if i press speaker, i can hear everything.
if i'm using mediaplayer, tcmp, youtube client, i get no sound.
even if i try to change the ringtone, i cannot hear when it plays for demo.
but if i plug in my headphones, everything works prefect, i can hear.
i have no headphones icon in the upper part of the display (so that the phone thinks i didn't get the jack out).
any ideea would be really appreciated.

Hi all,
i bought unbranded/unlocked HD2 on 5-6-2010 and played alots with it - so i didn't really noticed a serious speaker problem.
Within the first week i wondered about the fact that i sometimes couldn't hear the callers voice. I had this effect even when i called somebody. I thought about a software error - so i flashed to the latest german stock ROM.
But it didn't fixed the problem. I was only able to hear somebody, when i used the internal speaker or the headset.
One day i got a call and i "accidentally" pressed the phone speaker a bit harder than usual to my ear and the voice came and left - (ear)speaker defect.
I informed the dealer about this defect and i got a new HD2.
He told me, it would be the ninth HD2 with this particular defect since January 2010.
Please check your speaker for a defective contact - maybe it hits you too.
Good luck,
Stephan

mine was a software problem.
i have elegancia 8.5 now and it works, i can hear youtube, fm radio on the speaker.
the other thing that bothers me is that the sound i hear in a call is too low.
i don't know if it's a radio problem.
ah, btw, i can't use the volume hardware buttons, they are broke from a down fall, and i can't seem to find how to change in a call volume from windows.

I also hat that prob. The funny solution: Audio was set to silent in windows media player. After turning up the volume the problem was gone. I had this problem only one times. Strange thing...

I have the same problem with my hd2 now and still couldnt fix it.I have htc2 for 2-3 months, didnt have this kind of problem, no sound from the phone without earphones.can it be solved with any sound driver or sth like that, I tried hard reset, flashing, orginal rom, downloaded previous working rom, no solution.Appreciate if you could give some advices.thanks
note:happened after half an hour downloading laurentius 26 rom

??? help pls ???

My speaker stopped working last night. Had been working fine for the last few weeks.
Haven't installed anything or done anything different in the last few days.
Have only recently got my phone set up as I want it, so I'm loathe to do a factory reset. Read on another forum that HTC are aware of this and that 65% of HD2 owners suffer with is - not sure how true this is though.
If it's a hardware issue, is it easy to replace the speaker? If so, is it easy to order one?
Thanks
SC

I have the same problem! I have try like for ROM already and no solution i even uninstall HSPL to see if anything happened but not luck so far. can any expert or someone who have already solved this problem post a solution or something PLEASE i getting worried or i mean i am already!!
THANKS!

fixed It!! speaker Problem!HD2
well is was pretty simple! all i did was i put speaker volume on muted and with the earphone start to plug in and and out the jack several times while i was playing a video on windows media after that i unplug it and set the speaker volume up and hit play!!! speaker on!!!!

Just had the no sound from speaker problem, I always use my bluetooth motorokr s9-hd headset but i didnt feel like charging it so i used my sony earbuds with the 3.5 jack for the first time and it caused the no sound from speaker issue......I plugged the earbuds back in, played with the volume buttons on the phone and the speaker is back on

Problem with 2.13 and radio quality fix cab

Ever since I upgraded to 2.13, when i am on the phone i am able to hear my self talk through my ear speaker when used with the TX TMOUS radio quality fix cab.
Is there anyway to fix this? Without the cab the phone quality is unbearable, but when my voice is being output through my own speaker it is just as annoying.

try installing different radio, try the 2.12, it's working great for me. but make sure you have HSPL before you do anything.

Hi,
My friend gived me his old nexus one and I got problem with phone. During In-call the earspeaker making electronic sound with voice or simply cut. When I watching hockey in streaming the sound of earspeaker are perfect no crackle really perfect. I try stock rom cyanogen miui ics medroid and nothing work. I try different radio 5.12.00.08 5.08.00.04 4.06.00.12_7 4.04.00.003. Itry different kernel too. With a radio 4.06 et 4.04 the sound cut less but the voices have a electronic voice hard to understand. With BT or rear speaker no prob.
I need help i try everting and it can not be a hardware problem because it works well in stream?!?!?!
