android 耳机左右声道接反，软件如何修正

可以用如下方法:
修改AudioYusuStreamOut.cpp,添加方法:

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;
 
    }
 
   }
 
 }

修改ssize_t AudioYusuStreamOut::write(const void* buffer, size_t bytes)
在    dumpPcmData(streamout_ori,outbuffer,bytes,streamout_ori_propty);
之前添加: swS2M(buffer,bytes);
