hi...
i have looked into the alsa-jack plugin. i think i fixed the main
problem which made it cause xruns.
git://hochstrom.endofinternet.org/alsa-plugins.git
its working quite reliably here now.
with the small fix on the xrun front. i looked at the basic usability.
i removed the pid and weird stuff from jack client name. and added an
option to configure the client name.
------------------------------------------------------------------
pcm.jack {
@args [ NAME ]
@args.NAME {
type string
default "alsa-jack"
}
type plug
slave {
pcm {
type jack
client_name $NAME
playback_ports {
0 alsa_pcm:playback_1
1 alsa_pcm:playback_2
}
capture_ports {
0 alsa_pcm:capture_1
1 alsa_pcm:capture_2
}
}
}
}
-----------------------------------------------------------------
this makes jack:client_name devices available.
the noauto git branch also contains a more flexible not autoconnecting
version. use with your favourite patchbay.
------------------------------------------------------------------
pcm.jacknoauto {
@args [ NAME ]
@args.NAME {
type string
default "alsa-jack"
}
type plug
slave {
pcm {
type jack
client_name $NAME
}
}

mplayers alsa backend works fine with this.
after a bit of mucking around, i built a 32bit version here on my 64bit
machine and had 32bit skype connected to my 64bit jackd.
very cool!
would be nice if this could get some testing with
jack2 and stuff.
Tested with jackdmp 1.9.6 (32bit) works so far.
..but I could not get your .asoundrc working. It fails with
[AO_ALSA] alsa-lib: pcm_hw.c:1293:(snd_pcm_hw_open) open
'/dev/snd/pcmC0D0p' failed (-16): Device or resource busy
I've only replaced 'libasound_module_pcm_jack.so' and kept all other
/usr/lib/alsa-lib/*.so from default-debian. Could that be an issue?
here's the .asoundrc I'm using:
pcm.!default {
type plug
slave { pcm "jack" }
}
pcm.jack {
type jack
playback_ports {
0 system:playback_1
1 system:playback_2
}
capture_ports {
0 system:capture_1
1 system:capture_2
}
}
best,
robin
