Requirements:

I personally using Xperia S Locked Bootloader with Deodexed Stock .45 firmware. If u're the same then great. ;)

1. ICS Rom (RXE don't support JB Roms or XZX, Audio mod support ICS and JB)

2. Rooted and has CWM

2. Deodexed Rom

3. Xperia S/acro S/ion (MSM8260 chip/Cortex A8 with neon) (For V4A FX to work)

4. Recommended Clean Rom No need wipe DATA, just reflash SYSTEM, wipe CACHE & APPS LOG in flashtool.

(!) Unlocked Bootloader have to see tutorial to regain BE2 & DL Music Info

Instructions:

1. Make sure u met requirements.

2. Reboot into CWM, Wipe Cache/Dalvik-Cache

3. Flash latest build prop lines, flash AIO, flash RXE.

4. Reboot, After Android Upgrade, no bootloop.

5. Extract SDCard_V4A.zip to root of sdcard.

6. Done.

For custom rom, you'll face some apps FC, see solutions below.

Updating to v8

If u're on v7

1. Flash on top to overwrite. Build.prop lines same as v5.

If u're on v5/6

1. Recommended install on clean rom. Build.prop lines same as v5.

If u're on older versions:

1. No shortcut, Do a clean install. No need wipe DATA, just reflash SYSTEM, wipe CACHE & APPS LOG in Flashtool.

Updating build.prop lines

Important: Build prop lines should be flashed only once. Unless system is reflashed.

1. Reboot into CWM, flash Latest build prop lines zip.

2. Reboot, After Android Upgrade, no bootloop, Done.

3. If you are advanced enough, remove old buildprop lines manually if exists.

**Fix RXE FCs** (Happens on Custom Roms & Unclean Stock Roms)

ICS rom users,

Walkman + Download music info FC - http://xdaforums.com/showpost.php?p=37382215&postcount=222

Friend's Music FC - http://xdaforums.com/showpost.php?p=37442229&postcount=252

Album FC - Replace with the working album apk from ur rom

Movies FC - Clear Movies data in settings/apps/all

SoundEnhancement FC - Clear sound enhancement app data in settings/apps/all

Jellybean rom users, (almost every app FC)

So just replace those FC apps with your rom's default apk.

eg: WALKMAN FC - Replace SemcMusic.apk in /system/app/ with your JB rom's original SemcMusic.apk

**How To Switch Music Effects // Tricks to avoid Audio Conflict**

1. Shutdown WALKMAN.

2. Go Settings > Sound > Music Effects and select desired music effect, Minimize Sound Settings.

NOTE: Both XHiFi and FX will run together no matter which one u choosed in Sound Settings.

3. Start WALKMAN, go to Sound Enhancement and make sure its redirected to ur selected music effect. Return to WALKMAN.

5. Play Music. To test:

If u choosed V4A, Check FX/XHiFi "Driver Status".

If u choosed Sound Enhancement, Test Equalizer.

If u choosed SRS Panel, Set your SRS settings then restart Walkman to take effect.
