But after update my XZ to stock .230, my media sound doesn't work. However, system sound works, like ringtone and alarm.
In phone calls I can listen the caller voice but my voice can't be heard on the other phone.
A workaround for this issue is downgrade to 4.2.2. Any update above this make this issue reappear.
Try with clean install via Flashtool, it will probably fix that issue.
