Playback open error on device 'default': No such file or directory before do those, I've add some device node below /dev/snd/....(timer?controlC0 ?pcmC0D0c ?pcmC0D0p)? and the plugins necessary have be cross-compiled and installed. and the kernel I used is Android's kernel(some driver necessary have included in kernel), I just make a file system, I think it maybe due to alsa driver can not find correct audio device to playback audio file, is there someone have come across this problem and can help me? thx a lot in advance. -------------- next part -------------- An HTML attachment was scrubbed...
