Problem with Xperia S, Walkman app, A2DP and Poweramp
Hi, I need some help with an issue I've been suffering for a while.
My phone: Sony Xperia S, unlocked bootloader. ROM: Trinity Vengeance RaptorXL V3.4 T-Core Kernel.
The problem appears with the original Sony ROM and every 4.1 ROM Based on the original ROM that has walkman app.
I can stream music with my phone to the car radio (A2DP) using walkman app. No problem (except the bad sound quality that app has)
Well, When I try to stream from another app (like poweramp) it doesn't work. The player is working a playing music but nothing sounds and the LCD of the stereo shows "Searching.."
The only way to make it work is:
While Power amp is playing music I start walkman app and push play, I listen to music from wakman app on the car and poweramp pauses, then I pause walkman app, music stops, and LCD of the stereo shows "BT Pause". Then I push play on poweramp and music is playing on the car, and LCD still shows "BT Pause".
I think something is wrong with Walkman app and how sony use de android API.
This problem is solved when I use 4.2 custom ROMS, but camera driver doesn't work very well.
Thanks in advance and sorry for my broken english.
