Kernel without audio gain/boost/hack?

I am using one of pershoot kernels but the audio gain boost is driving me crazy the BT headset is unusable because it's too loud and also the speaker even at the lower volume set.
So I ask if there's another Kernel that have support for Froyo and 720P video recording without that audio gain hack?
Thanks !

Enomther's ROM has one that can be installed through SpareParts.

Cool, I will check it out.
This volume thing is too loud for me.

Check the sticky in the developer forum... There is a list of five our so kernels with links. I have had great luck with Wildmonks no-audio boost kernels.

Awesome! Thanks for the suggestions.

What exactly through difference between pershoots and wildmonks kernel? Other the no audio boost.

How to "boost" volume on CM7

I rooted my Nook to CM7 a week or two ago using what was the latest stable build at the time. I also tried to install dalingrin's OC kernal so I could reamp the volume and make it louder. I have since been told that kernal won't work with the stable build that I used, only the nightlies. So, is there another way to do it? I am not really concerned with over clocking at this point. I just need to be able to hear the dang speaker.

I really would just update to the next nightly or wait a bit for 7.1 to be released. We are mostly in a feature freeze at the moment so the nightlies are stable.
If you decide to go for a nightly then I'd suggest you wait for nightly 132, which should be out tonight.

And when you get that, install the Nook Tweaks app which allows you to boost the audio.

How well does this work? I've only tried using an eq to try and boost the audio with horrible results.

As good as it gets. With my app you can actually adjust the DAC and analog gain. So you can increase the volume and increase the sound quality.

Another app to look at would be Volume+. It's free on the market, and works beautifully at making the nooks speaker loud enough to be heard.

I used one of the apps that came with cyanogenmod 7... I think you can control the "phone" volume with nook tweak... You can overall gain sound by a LOT till you blow your speakers ( I used 40% boost), but you have to reduce your lowest bass and highest treble (left most column, and right most column) in the program where you can change the bass boost and equalizer? (Starts with a D.... )
Turn off bass boost too......
Hope That helps.

Since it has a Wolfson - Voodoo support?

I heard LG has not released the source of their audio drivers ... but I'm not sure if this issue is solved? Is there voodoo kernel support for the wolfson in the LG 2x? Got 30 minutes left for an auction to bid on, speedy replies would be nice

Dude, feel free to use the search function. Search for something like "voodoo sound o2x" and I'm sure you'll find what you're looking for

Voodoo works just fine in most custom roms, I think even on stock. I'm using it on my phone, works perfectly as it's supposed to, bug-free.

Nice to hear Happy with the audio quality it delivers?
@Kiljacken
Did! But got confused by all the kernel mentioned and some "will support" sentences etc and since I have less than 20 Minutes left for the auction i got a bit panicky Sorry.

Not really that much quality improvement so far, but a bit is there and boy, do I love it! Curio says his working on something more, but knowing him right he's probably distracted by all his other projects makes us feel a little left behind, but I think that it's worth waiting for some more stuff from him.

Well as long as it sounds better than my HTC Desire HD, it'd be nice.

I noticed a large improvement, but only when using proper headphones of course, the stock ones won't make the difference audible. Audiophile headphones however, really gets improved by voodoo, bottom end is more clear, and high end is more clean, less distorted.

on miui rom it's the same. large improvement while using headphones.
voodoo sound is just awesome

Well I got some UE Triple Fi 10's .... I expect a better quality ... that's why I started the whole Wolfson endeavour, to be able to drive those in-ears properly. That's also a bit dependent on the output impendance ... I hope the one of the LG optimus 2x is very low, so the frequency response doesn't get distorted with the TF10s. There's other dreams to dream about ... a BBE sound enhancer system or so
Btw, is voodoo in the stock kernels that come with MIUI and CM7? Or do you have to flash those custom roms and after that select a specific kernel with voodoo?

[i9000] Poor / Bad / Awful Sound Quality on CM9

Was very happy to see the latest "Stable" CM9 released a few days ago. Been using it, and it looks like a winner!
Then I listened to some music. Oi! What the hell, did I just bust my headphones?
The sound quality is awful to say the least. It's always been like this for earlier ICS builds.
Can anyone shed some light as to why CM9/ICS audio quality is really bad? Did a search and all I can find was a thread saying that the RC1 candidate had this problem due to an audio routing issue.
Thanks in advance.

Hi,
am looking to flash to cm9's stable release as well and seeing your post has made me think otherwise... so far are there any other bugs or issues you've encountered?
By the way, i've only flashed ROMS a few times, i'm currently running cm7.2.. is there any particular method to follow if i were to flash cm9? or do i just install the zip file through cwm recovery?
thanks mate! cheers!

The only major issue is the sound quality. I've tried CM7.2 and the sound is superb, with CM9 the drums turn to tin can drumming! LOL
What's worse if you enable any DSP effect (which is fab in CM7.2) it just makes it much worse.
Other than that, the build is stable fast and very nice! It looks like an entirely new phone altogether. Now if we can get this issue fixed on the sound, it would be a proper release!
I've tested using Apollo Player, PowerAMP and Winamp. All of them sound really bad.
Hope this helps!

An update. Apparently, the cardboard drumming is only apparent for AAC HEv2 converted files. It goes away listening to anything 128kbps or more. BUT! Sound is still nowhere near as good as on CM7.2. It's like night and day.

This may be an obvious question, but have you installed Voodoo Sound?

decided to flash cm9 already last night and everything went really well. flashed it in less than 10 minutes.
anyway, so far sound quality isn't really that bad. I'd say average. it's not great, but not bad. haven't tried any other formats rather than mp3s and wavs but they seem to sound okay.
have you tried reflashing?

Try devil3 ics kernel. Voodoo Sound should fix the probelm
Sent from my GT-i9000, cm10 alpha, devil3 1.1.3

Thanks for that, tried it out and also decided to flash to TAJB v7.1
It's a JB ROM based on CM10 and the devil kernel. Sound is better.

Thank you all for your replies. Yes, I have installed Voodoo sound. Well done on supercurio for creating that. Unfortunately, all it did was amplify the rotten sound signal. Just hearing louder cardboard drumming on it.
Have posted this issue on the CM forums and haven't received any reply LOL

Testing audio quality on cutom ROMs (CM and AOKP)
Hi there (audiophile here, so haters stay away)! Been searching the forums and Google for a discussion on this, finally found it..
Been looking for a custom ROM for my SGS (I use a SGSII as my actual phone, and the SGS as a separate media player, since I can completely strip the SGS BARE ), something to basically turn it from a phone into a media player (like the Samsung Galaxy Player) lol.. Because I heard great things about supercurio's voodoo sound and the wolfson DAC I had to give it a go
As a side note, voodoo sound gives me great amplifications without distortion and the sound is good. I don't think it's leaps and bounds better in QUALITY compared to the Yamaha in the SII, but the amplification definitely is (and I need the amp because I use beyerdynamic 32 Ohm cans which are pretty hard to drive )
Anyhow, I digress... Tried different ROMS, all with voodoo sound installed (i.e. all rooted). Tried stock Gingerbread, along with CM7.2 (Stable), CM9 (Nightly), AOKP M5 and M6.
Perhaps it is the "placebo effect", but I find the dynamic range and sound-stage is completely destroyed by the custom ROMs (or is it the kernels?).. The only ROM that I can listen to comfortably is the stock ROM (with stock rooted kernel by Chainfire). Does anyone agree with my observations? Would love to see if it's just me or I might be onto something?
I haven't tried CM9 stable on my SGS yet so maybe that's improved. But I am really torn. The stock rom is f***-ing (are we allowed to swear on these forums?!) slow! The phone is nearly unusable compared to AOKP/CM.
So what's the solution guys?! Are we tied to the stock rom to achieve the best audio quality? Or is there a custom rom out there that is lightening fast but preserves audio reproduction quality?!
Please discuss your findings here!
Cheers!

Thanks for your post there, I thought I was the only one! It looks like we won't get much more assistance as the devs are probably focusing on higher priorities right now.

I too have this problem. I used to have a nokia 500 , with which i had downloaded many original songs from nokia music , but since i used mobile data to download , the songs are 32kbps bitrate.
In cm9 , the bass cracks like anything. in cm10 , the bass is smooth and nice sounding. I tried copying cm10 audio libs to cm9 , but no changes occur.
The only way to solve this problem is to use songs with a bitrate of 160kbps +. Even then , cm10 has better sound quality. CM9 is a lot more stable , wish someone could port cm10 audio libs to cm9

Damn, cheers for that feedback. Nice to hear that at least the sound on CM10 is good! CM9 music... urgh... A pity since music is a major driver for me.

I agree with you...Sound quality improves to some extent by using equalizers apk in stock roms
I got good sound effects in vortex ROM & Ac!d player.Please try & let me know

[Q] Bluetooth Audio Distortion

I'm having an issue with distorted audio when connecting with my phone. I'm using a JVC KD-R730BT headunit if that matters. I read that some other people are having issues with bluetooth audio distortion (mainly in the higher frequencies), but no one seems to have a fix for this. Does anyone have a clue what I should do about this? I've been using an aux cable but I don't like it since I can't use headunit controls.

I remember older versions of bluetooth were so slow that you could only transmit low quality/pretty compressed audio over it. I'm not sure how much it's improved over the years, but this is certainly a possibility of your problem.
You could also try turning down the volume some on the phone. I haven't had a problem on my One distorting with max volume through aux, but I did with previous phones and mp3 players. Basically, max volume can cause the levels to peak and audio to clip - chop off the ends of the wave form. In other words, distort. See if turning the phone volume down some helps prevent this. Can't say it does as I don't use BT that often.

Turning it to about 11/15 helps a liiiittle, but it's mostly because then my volume doesn't come very loudly through the headunit so I can't hear the distortion that much.
Also, my EVO 3D and EVO LTE had no problems with this same headunit. Just this phone. I also got a replacement One since my original had light bleed and screen issues. The new and old ones both distort.

The bitpool rate is too low. I assume you're using a sense rom because that's where the problem is present. Unfortunately there is nothing you can do. HTC needs to raise the bitpool through a software update. Not even devs can do this because its closed source I believe.
AOSP roms should not have this problem.
I don't understand why they set it low in the first place. It makes no performance difference where its set from what I know. Its merely a limit raise in the code.
I explored this issue extensively on my e4gt because it had the same issue. I can link you to threads with more info later if you desire.
Rumor is that it may be fixed in the 4.2.2 update but I haven't seen it officially listed. If its there we won't know till we try it. And no telling when that'll be.

Damn HTC. That's really frustrating. Oh well. Here's hoping for the 4.2.2 update.

If this got fixed with 4.2.2 it would be amazing. It's annoying having to use the aux jack in my car with this phone when all the other phones I've had could just stream music over Bluetooth.

I wouldn't count on a fix being there though. Few users stream Bluetooth audio, of those few, only a small number notice the quality difference, and of those, only a minute number care enoungh to mention and complain about it here. So if it's on HTC's radar, it'd be nothing short of miraculous.
I'm hoping for the best with you guys though.
