Crackling distortion on calls - HD2 General

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.

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...

I'm running 2.08.50.05_2 and I have no issues at the moment

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

Operator name missing and camera issues

I've got a v1605 flashed with Schap's 4.30 WM6, which seems to be working pretty well... However, I've got two slight issues:
Firstly, at some point, I've managed to lose my Operator Name. It said 'vodafone UK' when I first installed the ROM, but now it's blank (so I get nothing in the dialer, Phone Settings 'Home Service' and HTC Home just says 'Home' - is there any way I can fix this? I don't know what I did to break it... I did search, so I'm sorry if this issue's been covered elsewhere already.
Secondly, my camera seems to be much worse than examples I've seen taken with TyTNs owned by others. I've got serious colour 'banding', almost like applying the watercolour filter in Photoshop! At first, I thought it was just because it was on a 65k colour screen and that they'd look OK once transferred to the computer. However, they don't - the banding remains. It's really odd, because it's sharp and relatively noise free, and the macro is really good, it's just this banding issue that seems to have persisted through the original Vodafone ROM, a Black ROM and now the current Schap's ROM, all of which have had different versions of the camera app. I'm wondering now if it's a hardware fault, since there doesn't seem to be any setting I've missed...
I think I'd better bump this before it gets buried. I can't believe nobody has any idea how to get my operator name back since there are quite a few threads about changing what's displayed. However, I don't want to 'hard code' it in the registry - I just want it to display the actual name from the network/sim again...
I think the loss of operator name was caused by Radio 1.54.30.10... I guess some permanent damage has probably already been done from what I've read here. It looks like 1.5x is really dangerous, and to say that it's designed for a specific operator and wouldn't cause any problems there is stupid. If I was a customer of a network which officially distributed a 1.5x, I'd be really pissed off as I expect to be able to take my phone anywhere in the world and not fry the radio! At least, I've never heard of the radio in a Nokia or SE with operator-branded firmware dying when taken abroad!
Even though they've never been released as part of unbranded firmwares from HTC, they must be aware of its distribution, and should really put an official warning up stating the dangers of 1.5x radio builds. Odd thing is that if I stick another operator SIM in, the name shows up fine. I hope it survives in the long term. I've flashed it fine with 1.47.00.10 now, although after everything I read, I left it sitting on the ledge of an open window for a while before flashing it off the SD to make sure it was cold (it seems the likelihood of radio corruption is much higher when the device is warm...)
Any ideas on the camera issue?
Edit: By the way, is 1.48 a known safe radio build, because I notice people are reporting better performance with it than other 1.4x builds?

No known/reported issues up to radio 1.49.xx - It's only the 1.5x.xx where a potential link to hardware issues is being investigated - but it has not been confirmed (ie. no hard evidence) so it's more about using a bit of caution. 1.5x deaths are suspected in UK, Germany and Netherlands as they have large numbers of recent deaths where 1.5x was being used and the death occured "spontaniously" ie - just happened when things were working fine for a while but no proven link. I agree however, that the risk at the moment with that radio is fairly real and advise people to use it with extreme caution or at least do their own research on users sharing their own operator/area.
While a radio update may cause your network operator logo to change a bit (as can changes in the ext_rom etc) it certainly shouldn't cause issues with your camera and I suspect that's something else at play.
In terms of fixing your operator logo - I don't know any other way than tweaking the registry...
Have you tried other OS Roms with updated camera software to see if they cure your camera issues?
Good luck! (new motto - Radios fine up to 1.49)
As mentioned, try flashing another rom for resolution of both issues. Otherwise, u can tweek the registry for the op name or do a hard reset.
I had it apart since I wanted to tighten up the slide mechanism and the camera wasn't properly connected - it just fell off the PCB, only held above it's socket by the nearby flash LED PCB...
I cleaned the connectors out and plugged it in properly, and it seems to be much better now.
As for the operator name, it did seem strange that it could be caused by the radio, but somebody else reported it in the radio death issue thread, so I did wonder. I'll try flashing it with a different ROM soon, anyway, since this one's a bit heavy on the memory usage and has some irritating issues with the dialer anyway.
Edit: Fixed the op name as follows:
http://www.modaco.com/content/HTC-H...44537/Nature-Weird-operator-name-on-SPV-C550/
There was an entry in the registry with vodafone UK's carrier ID as a series of whitespaces. How odd. Deleted it and the name came back. I wonder how it happened though.
Upgrade & camera issues
FYI ... I loaded Schaps 4.30 Hermes ROM and loved it. Ran great for several days and then I ran the latest Radio update to 1.54.30.10. After I did, several things went wacky, including my camera. I could not access my camera, not even through the camera or video launchers on the HTC launcher. I had problems with my keyboard too, but found changing the keyboard to Cingular (instead of English) fixed that problem.
I reloaded Schap's 4.30, but it did not downgrade the radio and my problems persisted.
So, I reloaded AT&T's office WM6 upgrade and it downgraded the radio and from that point on, everything worked great. I've since gone back to Schap's 4.30 ROM and having no problems with camera or video. But I'm not planning on upgrading the radio (at least for now). Schap's 4.30 took the radio to 1.54.07.00
I have an AT&T 8525 a.k.a. HTC Hermes 100. I hope this helps you to better troubleshoot your camera woes!
P.S.
I'm considering loading Schap's 4.31 ROM (released today), but ... considering all my ROM woes lately ... I think I'm going to wait until I can read some of the reviews on his latest ROM.

Any one have the same Issue? when calling or receiving phonecall, no sound

I have a HTC, with Chinese version ROM, Radio. 1.64.08.21.
this bug happens from time to time.
when I make phonecalls, I can not hear any sounds, also the other side can not when the call connected.
sometimes it is the same when I receive the phoncalls.
this happens ofenly especially when I use BT or headsets.
any one has the same problem?
Any one knows how to solve it?
Looks like a lame BT stack messing up with everything
If you quickly have a glance at the whole forum for Polaris you'll notice lots of people are experiencing the same problem, including myself.
I believe the BT stack is messing up with it. I dunno...
One thing I am considering is loading Android into my TC and then making sure it is not a design flaw. None of my previous HTC phones had as many problems at the same time as my Polaris does.
And it seemed to be the perfect one!

Strongly recommend that you revert back to your factory Radio or 1.54.25.14

I already say to you - dont be stupid.
Factory Radio ROM is 21.23 and its not solve problem with BT.
Radio 25.14 was recreated from Kaiser and very bad for most reasons.
And for future - think before any posts.
I got the same problem in the past when use the factory radio.

MY solution for crackling speaker... BUT...!

hi there. i made an interesting experience today:
i tested several roms to satisfy my needs while i always used radio rom 2.07. this was the best for me in battery life and sound quality... but like on all other radio roms i had the annoying cracks while i speak to my girlfriend (or every other woman).
some days ago i found the right rom for me: rtt shock rom rc7i german. i still tried to use radio rom 2.07 but there was a problem with it:
i can't hear the people talking on other side and my hd2 freezes when ending a call after that i gave one of the newest radio roms a try. it's 2.08... with a _02 at the end, and korean or chinese setup! my problems were gone.
but i gained another problem: the quality of calls was decreased - i have much more noise when talking to someone than with other roms. but what can i say:
i phoned several times with my girlfriend and all the cracklings are gone!!! i'm very happy and confident that there will be a radio rom and rom combination that will have no crackling and no noise.
maybe you just want to try out my combination (as there also exists a wwe version of rtt rom!) - but surely i can't promise that it also works for you! on the other hand you maybe share my confidence for next roms developed for our hd2!
thx for your attention!
p.s: excuse my english - as you can read above i'm from germany
radio 2.08 is optimised for T-Mobile USA and therefore some performance degredation can be expected in Europe. The poor call qaulity has made me go back to the 1.66 radio.
well i thought there will be more interest on this topic since there have a lot of people the crackling speaker issue!
but i'm not sure if i stick with the 2.08 radio, not because of the poor quality. it's the faster battery drain and the changes from hsdpa to GPRS even if i stay at the same place.
hopefully there will be a better radio soon!
even if nobody cares, i have to inform you that i found a good compromise
just installed radio rom 2.07.50.27_2. with it the battery drain is much better and call quality even has improved!
heard of a new radio rom 2.08.xx coming next week! it always can be better so i can't wait for it!
Have tried 2.07 and 2.08 radios and problem still there. I am just trying to live with it until a solution is found

Yeah but the fact is: I also tried this radio several times and the crackling didnt disappear. But it DID in combination with the RTT ROM. Dont have any clue why but there are some users in a german forum reporting the same... Maybe you want to give it a try... Do a FullBackup, flash RTTs ROM and the Radio... If it doesnt help go back and use your Full Backup. I dont know how annoyed you are of the crackling but this might solve it even for you

i don't know if it works for everyone in combination with a different rom, but maybe i would give it a try. the main reason why i have posted here (and on other forums) is the fact, that it is possible to fix the crackling since i thought long time that it is a hardware issue (posted on different forums too )
But it DID in combination with the RTT ROM. Dont have any clue why but there are some users in a german forum reporting the same...

nice to hear that it is fixed for you too! i thought it only worked for me until now.
I've tried two separate ROM now with the 2.08 radio and the problem is still there. Guess we'll just have to wait for a radio optimised for the UK/Europe...

Is it a microphone issue?

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!

[Q] Radio ROM or microphone problem??

Hello,
My friends complain about my call quality. They tell me that my voice repetitively gets extremely silent, so inaudible they often ask back so I need to repeat myself multiple times which is weird and aggravating at some point.
I have an EU HD2 with radio 2.15.50.14 and Rafdroid HD 4.0.2 NAND + data2sd. I had this problem back while I was still using wm65 Energy ROMs or my own custom built wm65 ROM, so I'm 99% sure it's unrelated to the operating system.
BTW I'm on T-Mobile Hungary. Gonna try my phone with Vodafone too, just to narrow things down.
Oh, and no, I'm NOT covering the microphone with my hand. I always hold my phone in my right hand when calling.
Anyone else had a problem like this?
Thanks,
Jay
Bumpity bump?
If you had the issue with the Energy ROM and your current ROM plus you have the most current radio version installed it my just be a issue of bad service in your area. You could try down grading your radio starting with the radio under the one you have and systematicly work your way down from there with the radio versions to see if you can find one that works better in your area. Go to the HTC HD2 Master Radio Thread to get the radios.

Thanks for the tip! Will try that.
I have exactly the same issue on my HD2.
Radio 2.07.50.27_2
Energy ROM: Energy.Leo.29007.Sense2.5.Cookie.2.0.Dec.27
I think for me this is a hardware problem, but it occurs very randomly and usually sound is ok again after some seconds.
JayMore, did you find a solution?
I have had this problem for quite a while also on older Energy ROM (same radio), but I never called very much. Now it is getting worse or I make too much long calls and I'm ready to RMA.
Try using a different microSD card, since I've switched, nobody mentioned this problem. Sounds stupid enough to actually do the trick...
Help!!!
My HTC HD2 is giving me problems....everytime I receive a call the caller gets a echo of his/her voice.....is there anything I can do to fix that????
Same problem here.
Usually when people phone me. If I phone back it seems OK.
Gonna try and rollback to an earlier radio to see if that works.
