beaglebone black audio cap sound problem

Post by tiblop »

Hello I have a Beaglebone Black and a audio cap. I can't manage to have sound and I don't know why. I've follow this tutorial : without any luck.. My audio card is detected, when I do :
aplay -l

**** List of PLAYBACK Hardware Devices **** card 0: EVM [DA830 EVM], device 0: AIC3X tlv320aic3x-hifi-0 [] Subdevices: 0/1 Subdevice #0: subdevice #0

is it normal that I have Subdevices: 0/1 ???

Also when i first turn on my BBB I can heard noise until I play a sound with : aplay -D plughw:0,0 sound.wav then I have no noise anymore ( ever) and no sound When I run the aplay with -vv option then I can see that it gets sucks and never ends. the pourcentage where alsa gets stucks changes everytimes .

Please help...
