How to fix the reverse signal on the left and right channels of an android headset

You can use the following method:
Modify AudioYusuStreamOut. cpp:

Copy codeCode: void AudioYusuStreamOut: swS2M (const void * buffer, size_t bytes)
{
Uint32 Idx_ I;
Int16 PCM_M;
Short * pbuffer = (short *) buffer;
{
// Enable software stereo to mono
For (Idx_ I = 0; Idx_ I <bytes> 1; Idx_ I + = 2)
{
PCM_M = pbuffer [Idx_ I + 1];
Pbuffer [Idx_ I + 1] = pbuffer [Idx_ I];
Pbuffer [Idx_ I] = PCM_M;
}
}
}

Modify ssize_t AudioYusuStreamOut: write (const void * buffer, size_t bytes)
In dumpPcmData (streamout_ori, outbuffer, bytes, streamout_ori_propty );
Previously added: swS2M (buffer, bytes );
