My opinion is that the bluetooth audio quality on the HTC Desire is terrible!
When playing music, in most of the tracks I hear clicking/crackling noise when some frequency/dB/something else is reached.
To illustrate what I mean, I have uploaded an audio fragment in which you can hear a similar noise.
Download fragment (MP3) Warning! it's drum n bass
You can hear the sound at the very beginning and at around 6 seconds (and at the end). As if a tweeter (speaker for higher frequencies) get overloaded.
I don't know if it is related to the phone's hardware, (radio) firmware or the Android OS. I've tried different music players, radio firmwares and custom roms. I also enabled an equalizer for bt audio using DSPManager. Unfortunately, nothing helped
edit: Using current versions of DeFoST or OpenDesire (and maybe others), the bt sound quality is how it should be! Fixed for me, but I hope an update from HTC will do the same.
Btw, this crackling/clicking is not only related to the HTC Desire, I have heard it on more (non-android) phones that were connected to my bt audio setup (in car). Unfortunately I haven't been able to test other Android phones, but my old Nokia N82 and SE K800i always sounded clear.
My guess is that it's just a non-controllable system setting of Android to solve the problem, but I don't know where (config/settings files?) to search for BT audio settings.
Any ideas?
That's the typical audio quality of a mediocre A2DP device: give a try at a Sony Ericsson MW-600 headset, you'll see what an Hi-Fi Bluetooth device is.

I'm running Defrost rom now and the sound quality is perfect, how it should be! So, it's not related to the audio device, or the default settings/drivers of the Desire are "too good" for my audio device (Pioneer BT unit @ car audio), which I think is not the case, since I also had this noise on my Logitech Pure-Fi.

Actually I recently owned this headsert but the quality of the sound was still terrible. I thought it was a problem with the headset at first, but that is not the case. I returned it and bought a Jabra BT3030 and the problem still persists. Anyone know if this is actually a problem with the phone or is it software related? I can add that I don't hear these noises when streaming audio through e.g. the youtube app, only mp3 and it doesn't matter which player I use (I've tried loads).
I have the jabra dogtags, audio playback sounds exactly the same as when my headphones are plugged in direct (tested it several times, culd not tell the difference), except that I have a louder volume via the jabra, which is all good as I listen to drum and bass also. Mabey device fault?
It is software related. Using current DeFroST or OpenDesire roms (and maybe others), bluetooth audio is great

well if it would've been device fault you'd think that I'd hear that noise through youtube streams as well.
But yeah as tutti-frutti stated it might be a software issue, which points me towards a root. But since I'd rather not root atm, anyone knows any other solution?
Might try a hard reset first and hope for the best. I will get back to you on that .
Thank you so much for describing my problem!!
I am currently downloading OpenDesire. Just in case that it does not work, where do i find DeFost??? I can't find it on the Market.
Thanks again!
I have Samsung Epic 4g.
nope Desire's Bluetooth audio quality is good in fact Awesome..!!
-May be the problem is not with the phone, its with Bluetooth head set you are using.
-My suggestion is to use Nokia or Motorola A2DP Stereo head phones
-I'm using Motorola motorkr S9 hd ,,,its awesome..!!
-Try this ,,it might work

For me, it is an issue with my car, not headphones.
A little UP!
Having the same issues with a Nokia BH-504 headset. Music quality is poor with every Sense ROM (original, rooted, Sense HD, whatever), sound like the tweeters are overloaded.
Definetly not a problem with the headset, it sound perfect with HTC Legend.
Tried to switch to non-Sense ROM (DeFrost, OpenDesire, etc.). The quality is perfect, but music play stops every 1-2 minutes for a second. Very irritating. Anyone experienced this? Is this a problem with my Desire, should I send it for warranty? (Don't want to send without enough evidence, don't wanna be without a phone for weeks...)
Okay, update: Tested the new Gingerbread AOSP and still having these stops at 2-3 minutes. Very strange...
Anyone any idea? Can I debug the bluetooth transfer somehow? Logcat didn't really show anything... Can it be a fault of the phone?

You need an sd r/w-buffer fix in kernel to stop that. I don't know if it comes with any senseless rom though. Maybe you could try the lite version of baadnewz hd rom.
Sent from my HTC Desire using XDA App

Thanks, I'll look into it. But if that's the problem, it would affect music playback with wired headphones too, isn't it?
And with Sense ROMs I have the overloaded tweeter-like problem, but no stutters. With non-Sense ROMs I have beautiful audio quality but music stops for a second randomly.
Update: Checked Aura ROM with sdfix, no problem with stuttering, but still the overloaded high-frequency problem. Meanwhile I checked that this SD fix is available only for Sense ROMs because it's HTC's hacking, the AOSP versions have no SD problems.
Oh, good lord! I was nearly to believe that I'm some sort of audiophile!
I'm using Plantronics 903 with my Desire and sound quality is just OK (I'm using SENSE ROM, will try OpenDesire in a bit). However, I cannot say I was expecting more.
What funny is happened today: I paired my 903 with PC today - sound quality was nearly same like my Desire, then I noticed someting in Bluetooth Setting Panel of PC. There was a combo box which labeled as "Audio Quality" and it was at the "Low" setting. I switched it "High Quality" and reconnected the device and voila! The sound has been thousands of times better!
Now I'm wondering if such a switch is also available in Desire? Maybe not obvious, but a Kernel variable perhaps? Damn that I don't know a sh** about programming these devices :'(
EDIT : Funny - I think that setting was not of PC's, but Headset's! It's quite well right now! And I didn't even try OpenDesire yet!

I have similar sound issues on non-sense roms. I believe it's mostly to do with range is just not quite as good as with sense based roms. I haven't had time to really figure out why yet.
Okay, so they replaced my Nokia BH-504 headset with a new one, still the same issue with Desire Sense ROMs but Legend Sense is still good. So it's not an issue with the headset (well, could be a general incompatibility problem, but I don't think so) Will check my laptop and a Gingerbread ROM on the Desire. Okay, conclusion after further tests with the replaced headset:
with Desire Sense ROMs: horrible quality in the high frequencies with every MP3.
with Desire non-Sense ROMs (OpenDesire, Gingerbred, etc): Good quality, but music play stops for a secons every 1-2 minutes.
with HP TouchSmart TM2 notebook: Quality problem AND music sutter BOTH
with HTC Legend original Froyo ROM: No problem
with Sony Ericsson X8: No problem
with HTC Touch HD: Quality problem
The headset has been replaced with a new one, same errors occur.
I have no idea what's wrong. I can't believe 2 phone's and a notebook's Bluetooth chip is faulty. So this could be an incompatiblity, hooray for great Bluetooth standard specification I should try a Nokia BH-905 and a Sennheiser MM400, will try them after buy (in the store!) and hand them immediately back if there will be a problem with them
Chapell, I have the same problem as you, with the Nokia BH-504 headset. So far the headset works great with the stock ROM, LeeDroid ROMs or just about any Froyo ROM. Gingerbread-based ROMs or Cyanogen nightlies, or any of the AdamG's Oxygen ROMS, on the other hand, they all have the same issue - every 90 seconds or so there is a glitch, the audio stream skips for half a second or so - very, very annoying keeps you from getting in the mood.
My observations: it is not SD card related, youtube video with the audio part streamd through the bluetooth headset also skips (also tried an SD read-ahead zip patch - no change); also, the glitch doesn't manifest using wired headphones; it has nothing to do with CPU spikes (the music player and the BT connection were the only open applications after a fresh ROM install); it has nothing to do with WiFi being on or off; it has nothing to do with 3G/2G network being active or not, or the GPS; using a different radio also doesn't help (scenario - radio X used with N.S.A. ROM -> no glitch; the same radio used with Oxygen 2.0 RC7 -> glitch)...
My guess - as noobish as it may be - is that this issue is related to some kind of buffering in the streaming process - I compared a few bluetooth configuration files in various ROMs, but couldn't figure any setting related to buffering or such.
If anyone could help, I would be very grateful!
Thanks for the info. If I understand correctly, you had no problems with BH-504 using Sense ROMs. So no high frequency distortion, nothing. This means that my phone is definetly faulty
However it seems the non-Sense skips are not unique for me. Strange, no one uses a BT headset with non-Sense ROMs or it could be a problem only with the BH-504?
I am having a problem with the headphone output. When listening to anything bass heavy... such as house music, the bass is distorted. Its sounds almost as if the headphones I am using are blown. I know this is not the issue because I have tested several different pairs, all with the same result. I even experience this when I have the phone hooked up to my car stereo. Volume isn't an issue and everything else seems to sound fine... its just that bass notes and kick drums sound horrible.
I'm coming from a Vibrant which was a powerhouse with voodoo sound enabled.
I understand that the Yamaha dac in the SGSII is nowhere near as good as the Wolfson used in the SGS... but it shouldn't sound this bad?!?!
I have tried just about every audio/dsp app available to no avail.
Does anyone else have this issue?
Also... not sure if it matters but I am running Juggernaut v3.7
Any help would be greatly appreciated.
hmm I was going to suggest you get power amp and just turn down the overall level in the eq. that might help in troubleshooting where in the signal chain the distortion is coming from. If it remains distorted at low level i would assume it wsa a hardware problem.
Ive certainly not any problems with distortion as long as i keep good gain structure in my eq.
I have tried power amp. I also tried lowering all the levels down. Nothing works
I forgot to mention that the problem exists even at the lowest volume settings... quite fustrating
I really hope it isn't faulty hardware... not sure ill be able to get a replacement
Completely different hardware but I had this issue on my HD2 after either making the lower frequency settings too high with other DSP or equalizers or when I used root level volume boosters like Volume Hack+
Are you using a stock (non-flashed non-rooted) build? If not, you can try a nand backup and flash a fresh install of your ROM. Not installing anything and go back to the same songs to see if they distort.
The SGS2 can push a good amount of low frequency granted you have earphones/equipment that can pick up low frequency output. I use it in my cars and with my Sennheiser headphones with no real issues and great output. Even with max volume, no distortion.
The HD2 was capable of only so much before it distorted but I haven't been able to replicate the issue with my SGS2. But then again, I haven't installed DSP or any other 3rd party volume/equalizer apps.
Im running juggernaut 3.7 w/ bullet kernel. To be honest I didnt check what it sounded like prior to rooting and flashing the custom rom. I only installed the dsp apps to fix the problem.
A new release just came out so I will take your advice, wipe and start with a fresh install.
Hope it fixes the problem.... its really driving me nuts.
Have you tried a different ROM? If not, try CM7 Alpha v3. Theres nothing like CM's DSP Manager.
Make a NANDROID backup first, that way if the problem still persists, you can always easily switch back to your current ROM.
I have done extensive testing with both my HTC One and Samsung Galaxy Nexus regarding the phantom ringing noise that exists on bluetooth audio. This issue is not only present on streaming bluetooth audio but also present when the sound file is kept on the actual phone (using Google Play Music). So far I have tried the following:
1) Tried multiple roms both sense and aosp - the ringing/buzzing noise still exists on both (DEFINITION - PHANTOM RINGING/BUZZING NOISE - a buzzing series of overtones that exists particularly when listening to jazz music that has a lot of ride and crash cymbals being played) As a professional musician, this can be quite annoying.
2) Tried going back and forth between bluetooth and auxiliary cable on both phones (HTC One and Galaxy Nexus), trying AOSP vs. SENSE roms, streaming vs. non streaming. Both phones and all roms have the same issue present, the bluetooth audio has a fuzzy clarity to the cymbals. It is worth mentioning that the AOSP roms are slightly better in terms of less Phantom ringing/buzzing but far from perfect.
My question is, does anyone have a fix for this? I paid big bucks to have Bluetooth installed in my car and really want to use it.
The auxiliary cable sounds good until you plug your phone charger in.....that presents an even larger noise issue. Please help.
Thanks,

if 2 phones and different roms still cause the problem then it might be your BT system.
what music player are you using / do any of them have an EQ system you can adjust.
what BT system do you have?

I am using an Audiovox Media bridge, however, I do not think that is the issue due to the fact that the issue improves slightly on the Aosp ROM. Additionally, when I run the aux through the media bridge I have no issues.
I am using Google play music. I have tried adjusting the EQ using Viper ROM 5.0 and have had no success. Any other ideas?
