Hi All,
I'm an alsa novice with a barely surface knowledge of alsa, and I could use some help troubleshooting a problem. I am connecting a Mac Mini (ppc) running the following to a Rega DAC.
miniG4:~$ cat /etc/debian_version
6.0.7
miniG4:~$ uname -a
Linux miniG4 2.6.32-5-powerpc #1 Fri May 10 08:12:18 UTC 2013 ppc GNU/Linux
miniG4:~$
Package: alsa-base
Version: 1.0.23+dfsg-2
Package: alsa-utils
Version: 1.0.23-3
Package: alsaplayer-common
Version: 0.99.80-5+b1
~/.asoundrc
pcm.!default {
type hw
card 1
}
ctl.!default {
type hw
card 1
}
/var/lib/alsa/asound.state
state.SoundByLayout {
…
}
state.default {
control.1 {
comment.access 'read write'
comment.type BOOLEAN
comment.count 1
iface MIXER
name 'PCM Playback Switch'
value true
}
control.2 {
comment.access 'read write'
comment.type INTEGER
comment.count 2
comment.range '0 - 128'
comment.dbmin 0
comment.dbmax 0
iface MIXER
name 'PCM Playback Volume'
value.0 0
value.1 0
}
}
I can play audio files through the AppleOnbdAudio - SoundByLayout analog port on the Mini, but when I try to play through USB port, I get the following error. I've peeked into other files, like /proc/asound/*, but I don't really know what to look for. Any pointers would be appreciated short of trying a different Linux distro. The man that sold me the DAC duplicated my system on a G4 MacBook(?) connected to an identical Rega DAC and got it working with relatively little effort.
I would be happy to provide additional information at your request. Thanks for your patience.
