Hello Donald<br>
<br>
The information on plant ccrma as well as the other tips you have
received are a little out of date... It is not necessary to black
list any devices, neither should you make make an <br>
<pre wrap=""><big>~/.asoundrc this will only cause a lot of headaches to get this right and alsa does it better automatically.
The trick on fc15 and fc16 is to make a relatively simple file called "sound.conf" (on unbuntu "50-sound.conf") and put this in the directory /etc/modprobe.d</big>
<big>
The contents of this folder will look something like:
# On-board audio vid=0x8086 pid=0x284b
# Logitech, Inc. Webcam C270 vid=0x046d pid=0x0825
# Behringer U-Control UCA222 vid=0x08bb pid=0x2902
# Edirol UM-1SX MIDI Adapter vid=0x0582 pid=0x0009
alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-card-0
alias snd-card-1 snd-usb-audio
alias sound-slot-1 snd-card-1
alias snd-card-2 snd-usb-audio
alias sound-slot-2 snd-card-2
alias snd-card-3 snd-usb-audio
alias sound-slot-3 snd-card-3
options snd cards_limit=4
options snd-hda-intel index=0 model=auto
options snd-usb-audio index=1,2,3 vid=0x046d,0x08bb,0x0582 pid=0x0825,0x2902,0x0009
In the above example, qjackctl always finds the semi-pro sound device under HW:2, regardless of whether the other devices are connected or not, or hot plugged later.
Note </big>"<big>options snd cards_limit=</big>"<big> must be defined otherwise the whole thing does not work!!</big>
<big>
For your set-up you will need to perform the following to find the necessary details
$ cat /proc/asound/cards                to find all the audio devices on your pc.
$ cat /proc/asound/modules                to find which modules are loaded for each sound card
The following is optional and only </big><big>necessary when 2 different sound devices use the same sound driver</big>
<big>
$ hwinfo --sound                        to find the vids and pids
</big><big>The bad news is that hwinfo is not in any of the fedora repos - if you need it which I don't think you will, I can send the spec and/or src.rpms as e-mail attachment so that you can build it yourself
hwinfo-18.3-1.2.2.sl.fc15.src.rpm >> 625,6 KiB
libx86emu-1.1-10.1.sl.fc15.src.rpm >> 57,0 KiB
Best regards, Simon

<pre wrap="">I have three sound cards:
0: motherboard
1: graphics card
2: RME card.
I want to use the RME card.
#cat /proc/asound/cards always shows that the RME card is card 2,
whether or not I blacklist the others.
I can get audacity to work if I set the output to hw 2,0. I can't
figure out what to put in the various alsa-related files to get the alsa
default to be card 2 (the RME).
Any help you can provide would be most appreciated.
Don
