Hi dmoti
I have follow your tips to implment alsa function.
I have built the libaudio.so, alsa_ctl, alsa_amixer and alsa_aplay on
android system.
I use a aplayer application to test the alsa function, but the audio
still not work.
Could you give me some suggestion?
Thank in advance.
Best Regards,
ehung
