Game lags and throws AUDIO_OUTPUT_FLAG_FAST denied by client due to mismatching sample rate (50257 vs 48000)

This is my third topic in the recent ten minutes, sorry for that but I have collected a lot of problems.

This problem is my biggest one.
The game lags a lot, and throws this:

W/AudioTrack( 8258): AUDIO_OUTPUT_FLAG_FAST denied by client due to mismatching sample rate (50257 vs 48000)

I don’t know if it’s because of the music or the sound effects, but it throws literally one every millisecond.
This is from the logcat:

Wow. Not a single reply.
