I recently got my HD2 from O2 UK.
Not content with the factory ROM, I began to enter the world of tasting different cooked ROMS. Soon also began trying different version of radio roms too.
I soon noticed my calls, my end only, began to get wierd crackling background noise. I first thought this was down to bad reception or caused by the other end. Making test calls, it appears to happen on my HD2 only during quiet parts of the call or when a sudden change in volume occurs e.g. start of a word. If I mute the far end, i.e. complete silence, then no crackling background is heard. Is like the noise is attributable to the auto gain control circuitry.
Doing a forum search I found others had the similar problem with crackling distortion but seem to attribute this to certain radio roms.
I've tried different radio roms to eliminate the problem without success. However I did notice some cooked roms didn't have this problem. After trying alot of different roms it seems like only cooked roms which support 576MB ram had the crackling distortion. For example, Miri wm65x_23529 which supports 576MB has this problem but not Artemis WWE 207_23529 which doesn't support 576MB. All WM6.5 roms (as opposed to WM6.5.x) don't have the noise problem either.
I would like to use a WM6.5.x cooked rom with 576MB ram but so far haven't found one yet.
Has anyone else found this too or know what's causing this?
Does anyone have any more info regarding this issue. I seem to be having the same problem. I'm using XannyTechROM Pandora 1.5 ROM with 2.08.50.08_2 RADIO. As first stated by the OP, I too have tried most of the other cooked roms which support 576MB ram, and so far I've had the same crackling distortion issue as described above.
What is interesting is that the OP is on O2 network and I'm on Orange; however, my friend who also has a HD2 is running exactly the same combination of radio and rom as myself, yet he's not experiencing any of the said issues what so ever! What could be causing this?
Any advice, ideas or input would be greatly appreciated!

I also have this crackling problem, but with original ROM. Haven't found any good solution jet.

What network is your friend on?
I wondering if people not having problem with 576MB roms have non UK sourced HD2.

Got a UK O2 HD2, currently on a 576MB cooked rom (see sig) and radio 2.07.50.27_2.
No issues at all with any aspect of calls. (or any other radio function), no crackle, no echo, good volume.
the crackling noise is one of the biggest problems on hd2. there exist a lot of threads about this. i also have this problem and it is really annoying!
at first everyone said it is a software failure but after testing different roms, radio rom versions and software i come to the conclusion that it is to 99% a hardware problem. even if the problem exists with headphone means that the hardware radio module has a malfunction! that's my theory...
anyway, i hope that it is just a software error which can be fixed. a lot of people already contacted htc with this problem but all they can say is:
"please make a hard reset..." or "we never heard of this problem"... that's a lie! i think they will gain some more time until warranty times expire
p.s: i have rtt shock rom rc3 and radio rom 2.07 installed, provider is o2 germany

Jepp i 100% second that !!! Seems to be problem with the radio module. Tried douzens of radio-rom combinations and the crackling is still there. Even hurts my ears when calling my girlfriend (female voices seem to make it even a bit worse). By the way: This is my third Device with this problem...
I don't think I can hear much crackling but do get a wavy distortion. It sounds like waves then a sudden stutter with no sound then the wave comes back.
I wonder if I need to install Rilphone.dll?
I heard somewhere when you flash a new radio you need to flash/re-flash the ROM after the radio flash for it to recognise the radio properly?
I will try out both when I get the time.
I had this issue with my unit in both phone earpiece and headphones.
It was a duff unit anyway (severe crashes and not booting up) and so i have another one coming tomorrow.
Will report back if the new one has it

The noise is so annoying to use as a phone now, it makes my old iPhone sounding like HiFi quality speaker.
Mine is only a few weeks old, maybe an idea to see if O2 would replace it as it seems a hardware related problem. Only problem is I don't have the distortion problem with the O2 rom to convince them with.
A couple of the radios had some really bad issues with sound quality. FWIW, I'm running 2.08.50.05_2 and I have no issues at the moment, but it seems to be different for you guys across the pond.
If you flash that and you still get bad sound quality, try flashing one of the 2.X.51.X radios. You won't have the extra RAM enabled - but what matters more, using your phone as a phone or some piddly ram?
And if that fails, I'd revert to one of the radios before these TMobile ROMs came out... they ARE geared for US networks and rev 3 of this brilliant phone...

did you had the crackling issue at high frequency (female voices) before 2.08?!

doesn't help in our case... i had this issue with all radio roms. from the stock one of 1.48 (doesn't know the version), to 2.06, 2.07 and 2.08!
i thought of giving it back, but on the other hand i don't want to wait for weeks just to get a phone with the same problem and maybe more of them like bad screen alignment or a more ugly touchscreen behaviour.

One of the radios... 2.06? perhaps? I had some really bad sound quality. Went away after I flashed off to another one.
these improvements of sound quality depending on radio rom version have nothing to do with the problem i (and a lot of other people) have.
you have to talk to a woman with my phone. after that you should know the difference betwenn my problem and yours
maybe htc will release someday a small fix to filter the high frequencies but i'm not sure if this will be possible anyway.
i got my 2nd hd2 today and can confirm that this unit does not have the crackling. hardware issue imo

Ever since I've owned this Shift, I've only ever known the microphone to work on one occasion, and then I started fiddling with flashing ROMs and Radios. Now the microphone will not work for nothing on either side of the Shift I have tried everything I can think of. I've heard that it depends on a combination of ROM and Radio, but I must of tried every single possible option and still nothing. Anyone have any experience with this? I can't just have a faulty microphone, it worked at one point. Any help would be appreciate. And yes, despite the fact that my iPhone 4 comes in the mail today, I'm am still very interested in playing around with the Shift. This getting it to call out and send my voice thing is beginning to mock me, and I'm taking it as a challenge.
Post #25 in Thaihugo's Age of Reason ROM thread gives the URL for a good radio ROM that works with his ROM.
http://forum.xda-developers.com/showthread.php?t=495143&page=3
So I'd install that radio image if I were you, and then install Thaihugos ROM. As far as I know, that combination is the most concrete base for your HTC Shift.
From there, you could see if your microphone works, and then move on to any other ROM/radio, keeping note of whether your microphone continues to work.
Hope this helps.
I noticed one bug. After I'm finished listen FM radio when i close it off, all sound on the phone suddenly becomes very low. I need then to go to Music player options and enable Dolby Mobile then the sound comes back to normal and then I can deactivate Dolby Mobile.It happens not every time but most of the times.
This happens only after listening to FM Radio not Music Player.
Same problem here :-(
yeah this bug has been mentioned in another thread around here. We need to inform HTC about this. I've already sent them an email. Everybody else should so they will realize this issue is quite widespread.
Have just send mail to HTC as well.
Got similar problem but a bit of twist. I've got a call while listening to the FM Radio. After the call, the phone won't switch back to FM or to be more specific, the FM app seems to be running but there was no sound.
On the side note, can any confirm the radio is really stereo? I am a bit skeptical but my ears ain't the best. It is certainly Hi-fi. Having been bite by SGS with their first FM radio version being Mono, I am just curious. I must also say that the Radio quality is not as good as SGS's.
(WOW: HTC CS called me back admitting the bugs but of course has no solid date for a fix ....it really doesn't bother me much as the phone is really great when compare to SGS. Besides, I used a BT with radio anyway. They have also noted my question about Gingerbread upgrade which they gave me an expected official answer...i.e. "As the OS was just released yesterday, we are getting more information. We shall let you know soonest possible once the situation clears up."...well, less than 8 hours of response time, what do you expected.)
I told them about this when I noticed it a couple of weeks after the phone came out. They fobbed me off with the 'do a hard reset' response.

at least they answered you HTC is too busy updating its old phones to 2.2 right now
and i'm sure they are delaying any coming update for the DHD to include gingerbread
one thing worries me though about gingerbread, i hope it doesn't come with its own set of bugs the Desire froyo update broke the SD card read speed for example, thank god we have custom kernels
Wrote to HTC yesterday in evening today got email:
"Dear XXXXXXX,
We are aware of this and are currently investigating the issue, Hopefully we will be able to find a root cause and resolve it as soon as possible. Keep an eye on our webpage for update announcements."
Is it possible that I have, as I saw after intensive reading of forum, microphone hardware fail? I have bought used TMOUS HD2 with stock rom 2.10.531.1 and as soon as I used it in Serbian network, microphone gets low in volume with background noise. The same is happening as I upgraded to latest stock rom 3.14.31.1. If I use bluetooth, everything is quite nice, which tells me it is not radio or network issue.
Here is a sample of my voice recorded by Voice Recorder.
Thanks for any help
Did you install Android? If you have the same problem in Android or some custom rom its probably defective.
I am thinking of doing that. Well, your oppinion is if it behave tha same, it must be hardware. Weird, no posts at all complaining mic!
Thanks anyway, keep you posted.
Happy New Year to all
After installing Android, mike becomes slightly better, but not OK. Could it be some driver issue? As soon as I get back to WM6, it got worse!
Hi all!
First of all i'm sorry for my english!
I think that a lot of people will agree with me that HD2 (with android) have many sound issues.
I may be patient with most sound problems, but not with microphone issue couse no one can understand me when talking with me.
My friends told me that they don't hear me clear, but i wasn't paying attention till i gave my phone to my friend for a week. When i called him i understood what are they talking about.
I heard him like FM radio with poor receptivity.
It feels like microphone is boosted to 100% and most of words aren't plain.
I tried to search the web and xda forum and didn't find any solution.
Someone in forum found issue with audio libraries in /system/lib (libaudio.so ; libcutils.so ....).
I tried to replace them with his files, but my rom was stuck on boot.
Does someone have similar issues? Knows how to repair? Something?
Unfortunately I have experienced robot voice both on Pongster's CM7 v1.0 & GBX v8.0 roms.
So, I tried gpc hd2 gb v2.0e rom which was released on March 9, 2011.
Absolutely NO robot voice & high mic gain from the 1st boot on two hd2s(tmous Leo 1024, Radio 2.15.50.14) in my home.
I didn't neet to turn off audible touch tones in sound settings.
Hopefully it will work for you too, mate!
