One place for Sound issue resolvment (2/24/11)

I am starting this thread as I work through the sound issue. I will be doing trouble shooting and tracking of testing here as I do my root cause analysis. Do to my work schedule I will need help from the community on ruling out the cause and getting down to the bottom of the sound issue.
So step 1 is to try and narrow down the cause. I have some ideas but need some testing first.
So here is what we know.
1. Sound is fine at stock
2. DHD roms don't have any audio with out custom kernel
3. Sound quality is bad on DHD roms with custom kernels to enable audio.
What I need to know to start.
1. Is sound ok on stock rom with custom kernel (2 confirmed audio fine on custom kernel with stock rom)
2. If using stock kernel on DHD rom is all audio gone or just for phone calls(still need to know this)
Start of testing
Again due to my time limits as of right now I am gonna have to rely on the community for my testing.(I do apologize).
I'm downloading Android revolution to look at whats in the zip after that I will be posting some more things to test. I have some ideas as to what the problem is. Unfortunatly lunch is over for me so back to work. Check back I will be updating again in a couple of hours.
If any one is willing to help please look into testing those 2 things.
I am pouring through the kernel source in the little bit of free time I have.
I will be handling this like I would an issue at work so some my be monotonous but thats how I work. So bear with me and we'll get this issue sorted out.
Also if some one would like to create a public google docs to allow people to post rom, kernel, and state of sound with that setup that to would be great. Hopefully work will slow down soon so I can devote more time. Also anybody else currently looking into sound fix can post ideas, info and test here to help keep the forums from getting cluttered from the same type of post, but thats up to you.

I'll flash the kernel over my stock rom and let you know. Stand by

# 1 is true, I used Bumble-Bee's kernel on attn1's stock rooted rom and the sound was perfect. Zero distortion in calls or audio playback through headphones. I am using some high end equipment to listen, so I would hear distortion if it was there. No idea on # 2, however.

Ok if thats true then we should be able to rule out kernel. That means its something in the rom. Ok lets get a few more test in and rule that out before I move on to the next idea.

I've heard it may be the lib files being out of date on DHD ROM's. I can't vouch for it, but it does seam reasonable.

Before making this statement, can we get someone else to verify please?
Verification from one person is good, two (or more) is better.

Interesting.
Stock Kernel Audio fine
Stock ROM with Apache14's Buzz Sense 1.30 Overclocked to 1.2 GHZ Audio sounds the same as Stock kernel and audio.

I rooted using attn1 hack but flashed the Revolution HD ROM .14 first. Sound seemed a little iffy, but not too bad. I then flashed Revolution HD ROM .15 Mike just released and the sound seems pretty good when I call my voicemail.

Confirming what I said. Same exact setup.

The sound issues are not in the kernel. They're in the csv files. We're looking at it. But they aren't compatible with DHD roms. They kill the mic.

are we sure there in the cvs and which ones are you speaking of.

So when sound "breaks", do the Dolby Mobile and SRS effects become unselectable on the HTC music player? Does selecting them do nothing to the audio? Or do they work just fine? Are those functions built in as simply an audio enhancement or something deeper?

Yes I'm sure.

There is no difference in the AIC3254_reg.csv files, there is a differnce in AIC3254_REG_DualMic.csv plus stock has an additional files AIC3254_REG_Dualmic_MCLK.csv and AIV3254_REG_XD.csv
Ok for a test some one do this on a DHD rom with sound issues
Download this zip and push the three files there to system/etc
DL link http://www.mediafire.com/?p1oiiqo26c5z37j
Be sure to backup the AIC3254_REG_DualMic.csv before pushing so you can revert back by removing the three files and pushing your backup back.
See if that fixes.
Again sorry for not being able to test myself atm.

Using CM7 RC1 DHD with attn1's kernel installed, after installing your files I hear no noticeable differences in sound quality.

I think these fixes are for Sense based ROM's, right?

You are correct I haven't downloaded cm7 to check file differences there.
Edit: I have found some more difference related to sound. I will attach to this post. There is a directory called soundimage in system/etc that needs to be replaced and all other files moved to system/etc as before. This is for DHD sense roms. Might work on cm7 not sure at this time.

I would have to think that the audio quality issue has to do with AMR-HR and AMR-FR codecs, no?

ROM: HTC Inspire 4G 2.0.15
Replaced files on my phone with files from the sound.zip file. Definitely sure that the original was deleted before pushing the replacements.
No noticeable difference in audio quality through phone speaker, or Mic when I leave myself a voicemail.

[Q] Bluetooth vs Sense 4

For a couple of weeks now the RUU for the HTC one S is out but i still can't find a ROM with bluetooth working. How is it that this still doesnt work and any other feature (hardware) was fixed within 4/5 days.
besides that, why are like 5 and more roms which all contains the RUU of the S, and futher only a downloadable kernel. I dont see the difference in a those roms, except for the developers own opinion of spamware. I believe there is a rom which uses install menu, so why not do the follow:
- make one basic rom
- fix what gotta be fixed
- and make a install menu where you can choice all app's to be installed. where only maps, telephone, message, play and browser is basic (maps since is not downloadable)
no offense but for me (as a noob, i can't deny that) it looks like where wasting time just because people are donate- & thanks- horny, where the mean goal should still be offering the user costumized or fully ported roms

well, when the fix comes out, every chef will put that on his rom...so, if you can't find a rom with BT working, is means that there is no fix out...
for your "ideal rom" I agree, there are too many customised roms, i like the stock feel (and I use arhd), if you want something like that I think that ordroid is the best stock like rom...is not working just bluetooth...
I still use arhd until an official relase of sense 4 will be relased...

I am also anxious to use sense 4, but the source has got bugs in it, and the chefs are helpless on this.

Mainly coz the user's don't post logcats?
If someone gave me a logcat of Bluetooth turning on/off in settings it can help pin down the file causing it then reference what has changed in Sense 4 to sense 3.6 then hopefully get it working.
As it is it will be difficult because the Bluetooth for sense 4 is Bluetooth 4.0 whereas sensation us only capable of Bluetooth 3.0 so there is probably a huge variation in the files

didn't it worked at the RUU of the one X, which also had bluetooth 4.0?

Inspire Audio Fix MIUI/BootManager

For those with problems getting audio with the latest MIUI and CM7 ROM, or even with them using BootManager (like me), you may try flashing this audiofix. Flashing this zip will fix audio to the INSPIRE 4G without downgrading to LC 8.1 kernel or without installing the Tiamat or TalonACE kernels (nothing wrong with them, I find them great). Tested with MIUI (last build tested 2.4.6).
For Boot Manager, I've tested it with BlackICE 1.50, CM7.2, MIUI 2.4.6).
DOWNLOAD LINK:
http://dl.dropbox.com/u/60526289/inspire-gb-audiofix.zip
This is "almost" the same inspiremod but with two additional files:
AIC3254_REG_DualMic_MCLK.csv and CodecDSPID_MCLK.txt.
NOTE: installing this in another ROMs may break sound (mic included) specially ICS. I'm not responsible for anything that may happen.
If you have any audio problems just delete the referenced files from /system/etc/.
MAKE A BACKUP FIRST

Thanks for this!
I have a canadian Telus Desire HD which is hardware identical with the Inspire 4G.
I'm running Lord Clockan's Ice Cold Sandwitch and in the main thread he had this posted for the Inspire 4G users.
I couldn't see too much of a difference with the patch or without it.
What happens on your phone if you don't install it?
Thanks again!

On LordC's rom this patch may break the mic, users may not here you, but I am not sure, I know twisted had issues in his builds when using the AIC file.
On the other hand you may not get any difference in LC's rom because the files are already in the ROM, I use his build and don't use inspiremod patch because of this.

So how does the ROM differentiate between phones?
Is it based on the cell phone provider?
Having the dual mic active is quite useful, isn't it?
The Moto Milestone I had before was quite good at noise cancellation with the 2 mics.
The 2 mics be used to record videos with stereo sound perhaps?
I'm trying your patch on my DHD, I'm curious what it will do.
Thanks

I tried your fix on RD-MIUI 2.4.13 and didn't notice any difference. The only problem I'm having is low speaker volumes (I'm comparing it to the sounds from a sense rom).
On a side note, how do I know if the dual mics are working?
Edit: I forgot what the edit was going to be. When I remember I'll come back.
2nd edit: just flash from recovery as you would any rom without wiping anything?

RD-MIUI is based on LordClock ICS so you may not need it. But I think I have something you can flash for low volume... Let me check something here...
Edit: here is something I found weeks ago for low volume, but haven't tried it. There is a file called "Low_mic_volume_fix.zip" give it a try, but backup first.

How do we know if dual mics are working? Is it activating a Mic near the camera/speaker area, or a second in the normal area?

I don't own the inspire anymore, but I think you could activate the dual mic with: snd3254 -dpsmode 0
Better way is to grab the file 30dualmic from inspiremod (original) and put in /system/etc/init.d/

Working ICS Roms if you want your Inspire 4G right on service after Rooting !!

A good Inspire 4G Rom is [ROM][AUG 23][ICS 4.0.4] aospX 1.0.0-BR7 | IMM76L | Source | WIP
You can get it here: http://forum.xda-developers.com/showthread.php?t=1460820
I'm using and testing this ROM since beta release 2 (BR2). There where some minor problems and a lot of battery drain.
After BR6 that ROM became better than stock roms Gingerbread 2.3.5, so anyone can switch and be satisfied.
Everything is working perfect except FM Radio. Even with SPIRIT UL and ICS Plus settings in audio method (as we read) is not ok. Actually plays for 2 seconds and then freezes. Also this freeze causes problem to device sounds generally and needs a restart to work again.
If you don't mind about FM Radio, is the ROM for you.
Another good ROM is: [ROM]31-08-2012 | IceColdSandwich - 8.6.1 - AOKP | THE RESURRECTION BEFORE DEATH
you go here: http://forum.xda-developers.com/showthread.php?t=1450962&page=1367
This ROM has more settings and launchers included and is more suitable for advanced users. I switched from aospX BR7 because of the FM Radio problem with SPIRIT UL since FM radio is a must for me. This rom is not exactly for Inspire 4G, actually is for Desire HD, but since those two devices are identical (except internal memory size and some other stuff) this rom is working great. FM Radio working for Inspire 4G with SPIRIT UL and ICS PLUS method in settings. The only downfall of this ROM is the camera video recorder that is not working. Sometimes shows the animation correctly and saving the video file, but is not working video file, is corrupted. Camera photo shoots is ok with fair focus.
So, if you have FM Radio reception as a must, this is the ROM for you, and then you have to live without camera video recording.
I wish there is a way to merge those two codes so we have a full working ICS Rom for Inspire 4G.
This is my experience while testing ICS Roms for Inspire 4G. If someone found a rom or another way to have a full functional ICS Rom for Inspire 4G including FM please post.

[Q] Is this rom actually for the inspire?

i was on the thread in android development that has the list of all the roms for the inspire 4g, but when i went to the cyanogenmod 10.1 it said Desire HD Android development at the top. is this rom actually able to run on the inspire?

DHD ROMs can run on the Inspire. They're nearly the same phone.

Some of the DHD ROMs like Jellytime have an Inspire patch you need to flash though, so watch for that. Otherwise, you should mostly be good. I'm new to rooting so don't just take my word for it, but they should work.

Yes you can run Desire HD roms on Inspire just use the inspire+mod pack. Its configures the audio and gps for the Inspire 4g. I attached it just download it. Flash the inspire zip after you flash the ROM. The beauty of this mod is that you can use just about any DHD made ROM as long as you flash this zip or your audio and other things will not work correctly.

And even then there's a decent chance it'll still work correctly, plus or minus a tinny sound effect. Personally I often forget to flash inspire mod, and I've never dealt with any major issues with it. It was designed for gingerbread, but so far every version of android up has worked with it (4.0, 4.1.1, 4.1.2, 4.2)
Desire HD= Inspire 4g with slightly more storage, a 3g radio, and marketed for Europe. The Inspire 4g has the exact same hardware, except with a 4g radio and slightly different speakers (hence the sound quality). The biggest difference is really in name.
Personally I'll find myself in the DHD threads more often than the I4G ones- they tend to be more populated and there's no difference.

Yes, it will run on the Inspire. I am running it now, and it's a little slow but pretty smooth and solid overall. Definitely flash inspiremod, although this is really optional.
