alsa configuration BBB
hello,
i have a beagleblack bone device and i have two different cards, one for play sound and one for record , the one for recording is usb when the otherone is pluged in the BBB. I'm trying to figured out what configuration file to have. For now i have : pcm.usb { type hw card 1 device 0 } pcm.internal { type hw card 0 device 0 } pcm.!default { type asym playback.pcm { type plug slave.pcm "internal" } capture.pcm { type plug slave.pcm "usb" } } ctl.!default { type asym playback.pcm { type plug slave.pcm "internal" } capture.pcm { type plug slave.pcm "usb" } } but it is not working. If I reload alsa then i cannot open alsamixer anymore( alsamixer work fine if i delete the configuration file ) : ALSA lib dlmisc.c:254:(snd1_dlobj_cache_get) Cannot open shared library /usr/lib/arm-linux-gnueabihf/alsa-lib/libasound_module_ctl_asym.so cannot open mixer: No such device or address and i cannot play sound : aplay /usr/share/sounds/alsa/Front_Center.wav aplay: main:682: audio open error: Device or resource busy configuration: debian weezy cat /proc/asound/pcm 00-00: AIC3X tlv320aic3x-hifi-0 : : playback 1 : capture 1 01-00: USB Audio : USB Audio : capture 1 please help thanks |
The error says you're missing a .so. Maybe use dpkg to figure out why it's missing???
