[Q] Terrible voice quallity in 2.2 Roms

Hi there everybody, I have friend with a captivate and i would like to try to see if we can get his problem resovled. Whenever he flashed over to a 2.2 Rom the audio quality ( what the person on the OTHER line hears) is terrible! The first one we tried was
http://forum.xda-developers.com/showthread.php?t=827153
AospMOd space man with the Setiron kernel. Then he called me and i noticed that the the audio i heard sounded literally sounded like a walky talky. It was really really bad.
So then we odin flashed back to stock and it sounded great just like before.
Now he's on AXURA with the default kernel (Setiron i believe anyway) and i dont think it sounds AS bad but it might just be my imagination. But i know it doesnt sound anywhere NEAR as good as the stock rom and kernel, stilll very poor in comparison.
Has anyone noticed this same issue? Anyone have any ideas on possible problems or fixes?
P.s. I am a EVO 4g owner and am active here on the EVO forums, so i know my way around android and adb and all that, so dont worry about scaring me with ideas lol
P.P.s I have no idea how it works on GSM, but i know on CDMA phones, we have a system menu through the dialer that lets us change whats called a vocoder. or basically, the audio codec/compression received from the tower and it specifically and directly is what effects our audio quality. im not sure if there is anything like that in GSM (more that likely not), but i figured id at least bring up the idea.

Yeah my friends and family complain about my voice quality also.. I think something is up with these roms?

It has nothing to do with ROMs and everything to do with modems.

I believe the instructions tell you to flash the JK3 modem file.

It's also worth mentioning that the Captivate has a special Audience voice processing chip that none of the other Galaxy S variants have.
While I'm not 100% sure about it, I don't think any of the leaked 2.2 ROMs or radios are actually using it at the moment. Especially if you are running a i9000 reoriented kernel. That means that instead, voice processing is being done by the modem. So this could be what you're noticing.
Personally, I'm using a i9000 ROM w/ SetiroN's kernel and I have excellent voice quality on both ends. But of course, YMMV.

Inspire 4G Volume Fix

Is it possible to take a stock kernel and fix just the volume without any other mods? This phone is perfect for the way I use a phone, except the volume is low. I wear hearing aids in both ears and having a little more volume would be great. I know there are custom kernels that have the audio boost in them, but they also have a lot of other things added to and I don't need any thing except the increased volume

Its possible, but what's the point if all the extra things help, but not hurt anything. Just don't use the overclock, you'll never even know besides the fact your phone will be faster and get better battery.

So dilligaf which one are u talking about

just ask one of the devs to compile you a stock kernel with only the audio boost. one of them i'm sure would be nice enough to do it. maybe a tiny donation would push them along.

Thanks fellows for the replys. I just want the stock kernel with nothing but the audio boost and as Roger suggested, I will PM a couple of the developers and see if they can do one for a "Donation". It shouldn't be a major challenge because several of them have it already in their Kernels.

Getting ready to compile, no donation required(unless you really want to)

Dilligaf your the $hit
Sent from inspire4G

here it is. stock, sound boost(all outputs, including headphones). 4.4.4 toolchain
let me know if its too much sound boost. its what im using in my latest kernel.
should still be a little faster than stock too.

dilligaf thank you and I will donate something to the cause. My only problem with the inspire is my hearing impairment (Hearing aids in both ears). I miss almost all of my calls and all of my E-Mail and text notifications. How much louder does your mod make the phone's notifications and ring tones? I hope it's a big improvement because I like this phone and want to keep it.
capman231

25% boost. Any higher and it may start getting distorted, dsp manager can maybe help a little with that, but you need to replace some libs for it to work. I'll make a zip if you want, I'm gonna do some testing with it myself.
edit- do you use any of the TTY or HAC options? if so, theres some sound settings i could increase for those that i saw in the kernel source.

With that much boost, if I can't hear it I won't never be able to hear it. Do you think it would ba smart to have the DSP just in case? Let me know what you find in your testing and I will download it when you get it tested.
capman231

The HAC doesn't work, HTC told me they know about it and it will be fixed in the Gingerbread update coming this quarter. The HAC works on an incoming call but the party on the other end can't hear me. Haven't tried TTY yet.

I am new to this, I downloader the kernel, now what?

I am new to this, I downloaded the sound fix, now what?

Flash it. If your that new, I suggest reading up.

I installed dsp manager and all it did was turn off all sound on my phone. Noone could hear me in calls and had no notification sounds at all. I had to do a full wipe and flash a different rom to get sound back cause it wouldnt come back with just a full wipe and factory reset with that current rom.

Read this thread, I posted that if you install dsp manager, some libs have to be changed out or it won't work. It's just a couple posts above yours

Nothing against di11igaf, cause his rom's are great, but Inspired Saga is the loudest rom I've used.
Not sure what the HAC status is on that rom, but it is a Gingerbread rom from a Desire S.

thanks somuch for the kernal

would your sound boost work with something other than a stock rom?

[Q] Xoom + Voodoo == ??

Hello, I am completely ignorant when it comes to technical knowledge of kernels and hardware in general, so hopefully some light can be shed on this.
I recently discovered the magic of Voodoo audio on my Samsung Galaxy Tab, and I was wondering if it is even possible to ever get voodoo audio on the xoom. I know that an amplifier is required, but I honestly don't know if every device has a qualifyingly powerful amp inline with the headphone jack. I really just don't know, and while I love everything going on in the xoom dev section, the thing that keeps me using my SGT7 over my Xoom is the voodoo audio, so I thought I'd post here and see what people have to say.
Thanks in advance for the help, and please excuse my nubbiness =)

I would suggest sending a PM to SuperCurio, the creator of VooDoo sound, and asking if the Xoom is on his to do list. I know VooDoo currently supports the Asus Transformer up to 3.1, so if he is working on 3.2 support, perhaps it can ported to the Xoom

Thanks, I will message him. I bought his pro version of voodoo sound because it is simply the best thing I have discovered lately...my headphones simply weren't made to be used without decent amplification =)

yea I have this on my G2X but like using my Xoom for music more. If this were to come to the Xoom i would be even more happy to own a Xoom.

[Q] Using a NS kernel on NS4G (Or Vice-Versa)

Are Nexus S kernels compatible with the Nexus S 4G (or the other way around)?
I've seen other report using Nexus S kernels on the NS4G and I'm curious as to if it really works. I'd rather not end up with a brick as a reward for curiosity so if anyone knows, any answers would be greatly appreciated.

some are made to work on both, some only work on one or the other. truthfully, it depends if the dev took that extra step to make sure that their kernel works on both phones. for example, trinity kernels work on both the nexus s and ns4g.

Idk but I'm on airkernel and the op made no indication that the kernel was ever intended to be compatible with ns4g. With that said, this kernel is a beast.
I also would appreciate more input on this topic. Can a counterpart kernel mess up your phone if the dev didn't include some necessary components to make compatible? Can a kernal be universal (ns and ns4g) without the direct intent of the developer?

the kernel needs the components for the ns4g radio to work or vice versa. if both components are there, then its universal ns/ns4g.

What does it mean not to have driver support for ice cream sandwich?

I can run all my games just fine. How does not having driver support for ice cream sandwich affect my g2x? Is it affecting my framerate in games at all and I'm not noticing.

The lack of drivers means done things don't work (like video recording) and others don't work right (strange graphical glitches in ICS)
I posted this in another thread, it kinda applies here too...
the problem most of the time comes from how the rom interacts with the hardware.
when an app needs to do something, it calls a function (for example turn on wifi) the rom gets this call and passes it to the kernel. the kernel then passes this call to the hardware which powers on the wifi.
APP>ROM>KERNEL>HARDWARE
a problem can occur at any point in that chain. the app can call a function that does not exist in that version of android, or the rom can call part of the kernel which is not there, or the kernel can try to do something that cant be done hardware wise.
oversimplifying it, porting a version of android is basically matching the function calls from the rom, to that of a kernel that works for this phone.
Now, alot of the problems we have been having with ICS on our phones is because of Hardware Acceleration. we have no offical kernel that supports it. without that we have no way for the calls from the rom to get to the hardware.
the INCREDIBLE devs at Cyanogen figured this out, they wrote those functions themselves. the part that makes this incredible is the fact that they did not know what to call, or where to send it. they had to guess at EVERYTHING! unfornately this also causes problems, while they may have gotten the functions 90% correct, 10% is still wrong. and that is what is most likely causing problems for us. (a stupid example i saw once is that they made a new brightness driver, but it was off by 1 number, so most of the brightness settings would work, but if you tried to set it to 0, it would really set it to -1 and all hell would break loose)
The reason it works so well for windows, is because when a hardware manufacturer makes a piece of hardware (wifi card) they also provide drivers that are pre-made for that version of windows, that way windows can call on standard functions, and that driver will answer those calls! unlike computers, phones very rarely switch hardware, so the hardware manufacturers only give the information of how to make drivers to the phone manufacturers
i hope you get what im trying to say.... i tend to ramble

That's what the devs did ie (legacy drivers = GB drivers) but ICS is so different from GB that drivers had to be rewritten that why some phones aren't getting ICS because some Manufacturers don't want to waste time writing them and then they want us to buy new phones. My 2¢

@ [email protected] Well said.
If you really want to take the time you can find drivers anywhere as well as the source codes for ICS (CM9.) Or you can find a rom that has the drivers already included. For example, CM9, HFS,EB, etc. The list goes on.

One other thing I've noticed about not having hardware acceleration in ICS is you can tell which apps are trying to call on it. Or at least I think.
For instance, the camera works fine from the stock camera app. But the new Facebook app installs a 'Camera' shortcut that is supposed to make sharing directly to facebook easier. Problem is, when I use that....it starts, flickers, and then crashes out.
Now, on Gingerbread, /with/ hardware acceleration.....it works just fine. So it's definitely going to be something we /need/ for ICS.
My 2 cents anyhow.

I didn't know that gingerbread has Hardware Acceleration!!??!
NO GB 2.3 (as far as I know) has any HA, the facebook thing could just be the fact that facebook is a crappy app in general lol. I do know it isn't caused by lack of "true" Hardware Acceleration.

Apps such as games have their own set of acceleration. Video cam illusion has its own. System apps like camera, browser, video recording use the systems ha instead of their own. Some non system apps require it. also mainly apps specific to ics require it as well.

I meant that GB has the drivers and takes advantage of the Tegra hardware in the phone. ICS doesn't.
Sent from my LG-P999 using xda premium

IMO if was a master coder ( I mean like the Steven Hawkings of coding) I would take the GB drivers and strip them down to binary and then figure out how they talk to the hardware on the lowest level. Then I would take the ICS drivers for the Gnex and do the same thing so I can see how the drivers work in a perfect situation. Then I would take the ICS drivers for a Tegra 2 tablet and do it again and basically modify the GB drivers or modify the ICS tablet drivers, combine the two or write my own drivers and I know I would be finished before LG releases ics

Gingerbread does not take advantage of the Nvidia Dual Core. This is why we are wanting Drivers released for ICS so it can.
