- Download AC!D audio technology (one simple zip file with all inclued Srs,Dolby,DSP,clearbass,... no more addon needed)
- Download Alsa Addon (only if it's availible for your phone)
- Download Walkman player addon (only if you need it)
- Download Ultimate Beat Addon (only if you want more bass on walkmann player)
- Put it in your SDCard
- COPY audio_effect.conf file located in system/etc into your SDcard (you might need this file in case of no sound issue)
- Reboot into Recovery
- BACKUP YOUR SYSTEM!!!
- If you flashed any of previous soundmod release reflash your ROM or restore a backup without any SoundMOD (only way to be sure there is on issue at all)
- Flash AC!DAudio.zip
- WIPE DALWIK CACHE and reboot
- In case of bootloop restore your backup
- If you don't have any Sound try replacing audio_effect.conf located in system/etc by the one you saved previously
- If you are on CM9 and CM10 go to system/app and rename DSPmanager.apk to DSPmanager.txt and reboot (I really suggest you to disable it because it may cause trouble with Clearbass EQ)
Done, Enjoy the awesomeness of Music!
Note: clearbass equaliser won't work on CM9-CM10, but clearbass sound proprieties are enabled
