I use Player Pro media player for my main media player. Something is messed up with the audio volume I believe. Whenever skipping a track the volume jumps dramatically to very loud with every track you skip even after adjusting it. I mean ear piercingly loud. I went through several volume settings to try to fix this.
I was a bit unsure if it was the rom or not being that I had flashed Ktoonsez kernel after my 4.2.2 vanilla rb install the other night.
So to be sure I restored a nandroid backup back to vanilla rootbox 3.71 - Problem went away. Volume worked fine.
I then flashed task 650 4.2.2. Volume worked fine.
I then did a clean flash back to the 4.2.2 vanilla rb again just to be sure without installing any different kernels. And the problem was their again.
I hope this helps to fix this. I really like Vanilla Rootbox ROM. Thanks for looking into.
