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.

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?
Whats the trick to play music on an external bluetooth speaker? I have the samsung hf1000 and i would love to play music on this while riding my bike, any suggestions? If im playing music and i launch the voice command to dial a phone number the speaker will play the music while waiting for a command. so is there a way to set the phone to play all sounds on the external speaker (bluetooth)?
wow guys no response. im sure im not the only person that plays music from there smart phone via bluetooth to an external speaker
I am interested also as I hope to use my Moto T505 with my car stereo. This is one thing I didn't test prior to ordering.
You wanna know why you're getting no response? Because you're posting in a forum that is completely and totally unrelated to the phones you're asking about.

BT on my G2 worked on my car's all-in-one head unit.. meaning all sounds (and music) plays thru my speakers.. but for some reason, the audio on it keeps cutting/skipping.. i doesn't do that with my iPod BT adaptor when its sync'd to my head unit.. but im not sure that was a first time error since i only connected my G2 to my head unit only once.. i'll test tomorrow maybe.
Well, I've been using InsertCoin-Vision v1.3 ROM (which in my opinion are among the bests) on my T-Mobile G2. With this ROM and with VIRTUOUS FUSION ROM by rmk I have no problems with the bluetooth A2DP.
Nevertheless, I had a A2DP bluetooth problem (reported here forums.t-mobile.com/t5/T-Mobile-G2/Post-OTA-Update-BlueTooth-issue/td-p/542367): when I connect my phone to the car stereo player (JVC AVX-33) thru bluetooth A2DP the audio cuts out and skips all the time when the music is playing (I use PowerAmp application). It happens with almost ALL ROMs, no matter if it's stock, CM6, CM7, xboarders or RMK's (Virtuous G-Lite for example)... except with the VIRTUOUS FUSION and InsertCoin-Vision (v1.2 or 1.3) !!!!
Well, I'm very happy about this fact, but I'd like to know if you could explain to me the difference between Virtuous Fusion or InsertCoin-Vision (where the problem is solved) and Virtuous G-Lite or Cyanogen7 (where the problem occurs) in terms of bluetooth libs, config, etc., that could have solved that problem.
By the way, I used to listen music with the same car stereo and my old Motorola Milestone and I had no problem at all.
Thanks in advance and excuse me to bother you with this kind of question.

Quick question, I have CM7.0.0 and I drive a Nissan Maxima. My friend also drives a Maxima. You can hear him perfectly fine through the Bluetooth but everyone who speaks to me can't hear a thing. Now is there like a custom Kernal or whatever to fix the bluetooth? Thanks in advance. I think it was actually good in RC2. Was there something different there with the bluetooth?

I know it's not a very helpful answer, but like the above I have no problems with it working with my headset (Sony Ericsson HBH-300) or the Bluetooth in my car (Ford Fiesta).
Possibily it's an incompatibility with your/friends make of car (which would seriously suck...), have you ever had it working though? Even before CM7?

Is it just me, but when I load any ICS based ROM on my DHD then the bluetooth handsfree stops working. It's the same with all my bluetooth devices (Ford built in handsfree, Jawbone Icon and Interphone Motorcycle Intercom). I can listen to streaming audio on all of them but no handsfree.
I've tried Viper, Sabsa, Virtuous Quattro and Infinity, Trickdroid and Primo S with the same result.
Anyone know what I am doing wrong?

Good luck !
