My Bose companion 5 is recognised by my Pi:
root@volumio:~# aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: Audio [Bose USB Audio], device 0: USB Audio [USB Audio]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 1: ALSA [bcm2835 ALSA], device 0: bcm2835 ALSA [bcm2835 ALSA]
Subdevices: 8/8
Subdevice #0: subdevice #0
Subdevice #1: subdevice #1
Subdevice #2: subdevice #2
Subdevice #3: subdevice #3
Subdevice #4: subdevice #4
Subdevice #5: subdevice #5
Subdevice #6: subdevice #6
Subdevice #7: subdevice #7
BUT:
a) when plugged in the web interface will not boot and I have to restart mpd with the command
/etc/init.d/mpd restart
which fixes that.
b) when the web interface is up no audio will play. Pressing play simply moves the counter forward a second or two and the message
[ 327.674562] 4:1:1: cannot get freq at ep 0x1
appears when
dmesg
is run.
I have tried replacing the -2 with 0 in the line # Keep snd-usb-audio from beeing loaded as first soundcard
options snd-usb-audio index=0 in the file
nano /etc/modprobe.d/alsa-base.conf
as suggested in other posts.
Some people have suggested it is a bug for which there is no solution? Could that be true? I am only an intermediate user and would have no idea about how to track down a bug that deep in the system.
