Chuck,
A few things. I'm going to assume you're using straight ALSA and not
Jack or otherwise.
Start off in a terminal and type:
cat /proc/asound/modules
This should give you a list of the audio cards that ALSA sees. It'll be
a list something like the following:
$ cat /proc/asound/modules
0 snd_hda_intel
1 snd_usb_audio
Next, it sometimes helps to lock this audio card order in place via the
/etc/modprobe.d/alsa-base.conf file. If the file exists on your
computer (you'll need to be root to edit it) then you may need to edit
it. If the file does not exist then you may need to create it. Use the
Options line(s) to lock the card order in place. For example, the above
can have the Intel and USB order being 0 and 1 by having the
/etc/modprobe.d/alsa-base.conf file looking like this:
options snd_hda_intel index=0
options snd_usb_audio index=1
Once you've set up your /etc/modprobe.d/alsa-base.conf file then when
you reboot the audio card order should always be what you specified.
Then set up your card(s) in rdalsaconfig
Double check your /etc/asound.conf file - I've found that a number of
onboard chipsets need the rate line to specify the bitrate, and older
versions of rdalsaconfig didn't always put that line in there. You'll
need to be root to add this line if it is missing. Add the line for all
the audio cards in your setup and use the same sample rate for all your
cards. So for example:
pcm.rd0 {
type hw
card PCH
device 0
rate 48000 <-- This line is sometimes missed
}
ctl.rd0 {
type hw
card PCH
}
Once this is done, restart your rivendell services and see what you get.
Hope this helps
