Hi there:
I am trying to use my RPi B 256MB as a music server, and have decided to use mopidy.
So far, I've had success playing music through the default bcm2835 device.
However, I have found an old Xitel DG2 MD-Port USB sound card in my technojunk box which I thought should be able to pump out far better sound that the standard equipment.
I connected it, and to my utter surprise, the kernel recognized it instantly.
However, I have so far failed to redirected the sound output to USB.
Here are some outputs I get:
$this->bbcode_second_pass_code('', '
$ aplay -L | grep :CARD
default:CARD=ALSA
sysdefault:CARD=ALSA
default:CARD=DG2
sysdefault:CARD=DG2
front:CARD=DG2,DEV=0
surround21:CARD=DG2,DEV=0
surround40:CARD=DG2,DEV=0
surround41:CARD=DG2,DEV=0
surround50:CARD=DG2,DEV=0
surround51:CARD=DG2,DEV=0
surround71:CARD=DG2,DEV=0
iec958:CARD=DG2,DEV=0
')
which bothered me as this says that there are two default cards, and evidently, ALSA defaults to onboard!
So, I tried to prevent ALSA from using onboard by editing the folllowing:
$this->bbcode_second_pass_code('', '
/etc/modprobe.d/alsa-base.conf
options snd_bcm2835=-2
options snd_usb_audio=0
')
and
$this->bbcode_second_pass_code('', '
/etc/asound.conf
pcm.|default {
type hw
card DG2
}
ctl.|default {
type hw
card DG2
}
')
then reboot, and still no luck.
When I run alsamixer, it ALWAYS defaults to the onboard card, no matter what I throw at it.
If anyone out there has successfully changed the default sound card, I'd love to hear from you !
Or, should I try to trick the system by using JACK ?
Any comments will be gratefully appreciated.
