Hi all, i am using an embedded board with At91SAM9G20 chip connected to the codec wm8731. I am a newbie on audio env, so please help me suggesting how to procede. The problem is tha I have no sound on the headphone output. I suspect something wrong on the alsa configuration because no codec dir is present : ls /proc/asound/card0/ id oss_mixer pcm0c pcm0p some info: aplay -l **** List of PLAYBACK Hardware Devices **** card 0: AT91SAMG20EK [AT91SAMG20-EK], device 0: WM8731 PCM WM8731-0 [] Subdevices: 1/1 Subdevice #0: subdevice #0 aplay -L null Discard all samples (playback) or generate zero samples (capture) default:CARD=AT91SAMG20EK AT91SAMG20-EK, Default Audio Device Let me know if you need more infos. thanks J ------------------------------------------------------------------------------ Ridiculously easy VDI.
