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

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

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?

Luke

Hello,
first of all thanks for your mail
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. Now, that is what my .asoundrc looks like:
pcm.powermac {
type hw
card 0
}
ctl.powermac {
type hw
card 0
}
when I launch jackd, I have the same error messages:
titanium:~# jackd -d alsa -d powermac

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.
alsamixer works fine, I also tried to rmmod all the modules that have
"oss" in their name, no change. These are the modules that are loaded:
titanium:~# lsmod

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? xmms works fine with output "libOSS.so", with "libALSA.so"
it
plays the songs a bit too fast, I think I've read something about this
in the mailing list. Do you think it has something to do with it?

Thanks a lot for helping me

Have you checked that the nodes are there? Look in /proc/asound/dev and do

Hi
I'm interested in your problem, but I'm a newbie who's just been wrestling
with a similar problem, so don't take anything I say as definitive.

Your card does not have capture capability, or very many devices at all!
advice I was given on this matter: [thanks Bob]
If you do "jackd -d alsa --help" you'll get a list of options
for the alsa driver. Try giving it -P (which makes it use playback mode
so it won't try and set up capture.)

I don't _think_ you want to remove the alsa oss compatibility modules, all
the modules with snd- prefix are alsa modules.
Good Luck

Hi,
Looks that your card doesn't have capture capability, I think that
the "c" on /dev/snd/pcmC0D0c stands for "capture" and the
"p" in
/dev/snd/pcmC0D0p stands for "play" (but I may be wrong)
try starting jackd with -P
