[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

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

[SOUNDMOD][05/05]FidelityXAudio - Ultimate high fidelity audio

I'm building a new ROM for my new Xperia Z right now mainly for even better audio quality. However, it'll take a while as I plan to try rebuilding audio driver library file for lower latency. Right now I'm on vacation staying at my parents' house so I decided to build this sound mod for Samsung WM8994 devices instead since I have good chance to reunite with all of them right now.
FidelityXAudio is based from PureXAudio for Xperia Z/ZL made by ZeroInfinity. I asked him for permission to derive his works with mine for all-in-one sound mod I plan to release for various devices that support Alsa driver. For this first release, it'll support Nexus S, Galaxy S, Galaxy Tab and Galaxy Tab 10.1 and all variants. Installing this mod will give you the following features below.
Features:
Rooted & Busyboxed - This will replace current root and Busybox with latest SuperSu and Busybox. Since most root access for Xperia Z I tested are so unreliable getting bootloop after mounting system rw, I'll force better ones in this package to avoid that problem.
exFAT support - If you're using Android JellyBean ROM but still not have exFAT support yet, this may help you getting one. It works for Xperia Z/ZL but haven't tested for others yet.
init.d support - This isn't cheap recovery flash init.d script. It'll execute init.d script with root access from hardware boot script level so it works far better than conventional ones for locked bootloader running stock kernel.
Xperia Fidelity script - It's ultimate sound quality mod script I've been developing for years. Not only get you better sound reproduction but also make your system smoother as well.
PureXAudio engine - As FidelityXAudio is based on PureXAudio mod, most PureXAudio features are availble except audio effects and specific sound card stuff. I may consider adding them back later though.
Low latency tweaks - My tweaks inside PureXAudio for lower latency Alsa configuration. Not sure how much of it works though as real measured hardware latency won't change without modifying driver.
Mastering 64-bit quantization - The most accurate 64-bit floating point quantization in Android. I usually end it with 32-bit integer mode but this sounds better for crazy upsampling level.
DSD128 audio processing at 5.6MHz - This will give you high resolution audio simulation. The real sampling rate will still be 44.1KHz but with 128x upsampling for audio processing before downmixing is really something.
Fidelity nVIDIA audio configuration - Optimized for more direct bitstream with lower latency. Only for Tegra devices though.
Removed DSPManager for more solid audio performance - This mod breaks DSPManager in CM ROM so no point in keeping it and you probably won't need it anyway after hearing sound with this mod.
Download: PureXAudio v1
You can't flash this on other devices as it can break audio with incompatible sound card configuration. I tested on my Nexus S, Galaxy S, Galaxy Tab and Galaxy Tab 10.1 and they're all working fine. Guess not many people still use them nowadays but they're great ones for sound quality wise. I'll update again for APQ8064 based devices in next version after releasing new Xperia Z ROM.

Wait I'm trying it will report back soon:thumbup:

Yeah its working well and i can hear a little bit difference in the sound but the music sound is loud now So, its working awesome :victory::highfive::good:

I can use this on 4.2.2 rom ?

It's designed for JellyBean ROM so yes.

Yes i tried on a JellyBean 4.2.2 Rom and it is working well :good::good:

Don't know if its a placebo but I seem to be able to crank up the volume much higher now before it starts to sound distorted, on lower volumes I cant hear any difference
anyway thanks for the mod will start using it daily and probably damage my ears :laugh:

Huh?.. can you speak up.. I can't hear you over this great mod!!

someone please reup this, thanks

Will this mod work alongside voodoo sound, or is it an alternative?

It works alongside with Voodoo Sound. Actually, I added my own Voodoo Sound tweaks as well. Some may not like it but that's what I prefer.

What headphones/earphones/speakers do you usually use with your devices?
This information is useful for me. Thanks! :good:

I used to try all in market years back but now I don't really care much even R10/Orpheus failed to make my desire go wild now.
My current favorite earphone is Martin Logann Mikros 70. Not very bang for bucks but easy to wear with mic and bass sounds like speakers with dynamic driver in that long housing.
My current speakers is Rockport Ankaa. I like it more than its newer Avior models.

hello I flash this but I don't think is working for me..i don't find any different ...
I install busybox again with busybox.apk is ok ??

If you already use other soundmods, maybe it's possible that this won't work. Otherwise, I don't see any reason why not as I already included root/busybox/init.d stuff.

I don't use other soundmod.. I don't know maybe I don't understand the sound ... for busybox I install 1.21.0 ..

It works on JellyShot 4.2.1 v1.3? I flash it with CWM? I have Voodoo sound... It works fine too?

i'm sure that you will make this face when I tell you that i'm using CyanogenMod 7.2...
... so the question: it's only for 4.2.2 roms or it will work with every android os?

Should there be an app to control this?
Me Gusta!

i9305 vs i9300 sound quality

Hi,
I'm new to Android. I tested once my Logitech UE6000 headphones (which i highly recommand) with my friend i9300 phone and was amazed by the power and quality. I then decided to buy a i9305 so that i could have extra RAM and 4G but i can't get the same sound. I have already rooted and tried two ROMS :
[ROM][5 JULY][XXBMF1-V17] Ripper Rom Smooth, Stable [OTA,JKAY,240Dpi,Customizable]
and
[ROM][LINARO][30/06/13]SentinelROM v4.80-CM10.1 Source-Fast, Stable, Battery[GPL]
I wanted to try the audio boost mods (the ones that modify Default_gain.conf files) but i realised this file doesn't exist on i9305. So i'm wondering if the i9305 do have the Wolfson audio DAC first and then if there is a way to boost the volume

the thing is it doesn't that's what you get for the cost of 4G and 2Gb of ram

Actually i thought i had made enough researches but not
I did a cat /proc/asound/cards and was able to see the WOLFSON. I had to put a 4.1.2 ROMS as it seems the 4.2.2 with CYANOGEN 10.1 don't have the default_gain.conf file. I don't know why but whatever my problem is fixed and i can enjoy amazing sound quality now

[Q] Which ROM for music?

Hi all,
I have a i9305 lying around at home. Was thinking of turning it into an iPod of sorts. Just to take to the gym - listen to music mainly, and some small app usage.
Just wondering which ROM is more optimised for music/sound? Any recommendations would be great
Thanks!

Get the latest version (3.10 I think) of the AMCHA ROM. It comes with the PUREAUDIO 2.0 mod, superb!

Seeing as the use isn't too hifi, I'd guess pretty much any decent combination, say CM with Boeffla, would do pretty well?

[Q] CM11 or Sense 6?

lock.

Hi guys, wanted to ask for your opinion. I am running cyanogenmod on my m7 ever since i got it, but i often feel as if cm11 is not so optimized for m7. battery life is poor, the sound when I play music just doesnt sound as crisp as it was on the stock sense, its not the beats audio that is so good, its that the cm11 dsp manager makes the sound sound like ****, when you turn bass on or any equalizer, the speakers start making distortions. i loved cyanogenmod for their dedication and persistance as for security and customization but i feel as if the really took more than they gave, that is as far as for the htc one goes. i find myself playing game up to 7 minutes and the phone gets hot i could worm my sandwich on it. my question is what do you find to be the best rom for htc one as far as for best performance and stability?

Forum rules prohibit comparing ROM. You will have to visit the post of the ROMs and find out which would work best for you then flash it and give it a go.
