Package: alsa-utils
Version: 1.0.16-2
Hi,
Stock lenny system. When jackd is running (with
“jackd -d alsa -d hw:0 -r 44100”), programs cannot talk to ALSA
(device or resource busy). So I think, “maybe it will work if
ALSA uses jack as a backend”. Luckily, libasound2-plugins
includes a file /usr/share/doc/libasound2-plugins/README-jack
explaining how to set this up.
Unfortunately, the instructions do not work: after setting up
asound.conf:
$ aplay -Djack "Yardbirds - Birdland"
Playing WAVE 'Yardbirds - Birdland.wav' : Signed 16 bit Little Endian,
Rate 44100 H
aplay: set_params:918: Sample format non available
and no sound is output.
Eventually, I did get alsa output through jack working, using
the instructions at <http://alsa.opensrc.org/index.php/Jack_(plugin)>.
Those indicate to use this configuration file:
pcm.!default {
type plug
slave { pcm "jack" }
}
pcm.jack {
type jack
playback_ports {
0 alsa_pcm:playback_1
1 alsa_pcm:playback_2
}
capture_ports {
0 alsa_pcm:capture_1
1 alsa_pcm:capture_2
}
}
ctl.mixer0 {
type hw
card 0
}
The version in /usr/share/doc/libasound2-plugins/README-jack
is missing the pcm.!default and ct.mixer0 stanzas and misspells
capture_2 as pcapture_2.
With that expanded configuration file, most files play out of
the box, and for example, “aplay "Yardbirds - Birdland"” works.
But still “aplay -Djack "Yardbirds - Birdland"” still fails,
and with the same message.
Any ideas?
Thanks,
Jonathan
