Hi raph
For a start, you could rewrite the .asoundrc file to reflect the type of
card you have. For example, this is what my .asoundrc file looks like, and
I am using an envy24 chipset, which uses the snd-ice1712 module.
pcm.ice1712 {
type hw
card 0
}
ctl.ice1712 {
type hw
card 0
}
Then, I can launch jackd like this:
$ jackd -d alsa -d ice1712 &
Substituting ice1712 for the name of the sections defined in .asoundrc. So
you could could simply use:
$ jackd -d alsa -d myname &
going by your current .asoundrc file.
NOTE: The & afterwards makes Jackd run in the background, so you can
proceed to load a jack client, like Ardour.
Have you double-checked that the correct module for your soundcard is
loaded? Have you run alsamixer to see if the volume is turned up for the
card's outputs? It might also be good to ensure that you have no OSS sound
modules loading either.
Are you able to use the ALSA drivers with other software like xmms, or KDE
to play MP3s and the like, both through OSS emulation and ALSA itself?

Hello,
I would like to use ardour. I downloaded it from CVS and finally got it
compiled, but I can't start jackd:

I could not find more details in the documentation or on

Here is what I have in /dev/snd/

There is really no /dev/snd/pcmC0D0c
What am I doing wrong? I tested it with alsa started and stoped. Did I
misunderstood anything essential? I'm using debian woody on a Mac
PowerBook G4 with alsa 0.90rc7 from sid and with a special mac kernel
2.4.20 (from benh).
Thanks very much for your help
