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
