Hi,
i use ubuntu gutsy betas and i try to get the alsa pcm jack plugin to work. I
copy here from the bug report i commited to ubuntu:
Binary package hint: libasound2-dev
Install libasound2-dev and libasound2-plugins. Note that the previous ubuntu
release removed the alsa jack plugin from the libasound2-plugins package
without replacement. It was nonetheless still possible to build it from the
corresponding alsa-plugins source tarball and then simply copy it
to /usr/lib/alsa-lib/..
Sadly with the gutsy betas even this isn't an option anymore. While it is
still possible to build the alsa-plugins-1.0.14 tarball against the 1.0.14
ubuntu libasound2-dev package, the jack plugin simply doesn't work anymore.
Here's a testcase for you guys:
start jackd [if realtime or not doesn't matter]
add this to your .asoundrc:
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
}
}
pcm.jackplug {
#pcm.!default {
type plug
slave { pcm "jack" }
}
And then on the console try:
aplay -D jackplug some_wav_file.wav
I consistently get this error message:
~/sound/Ardour_Sessions$ aplay -D jackplug nuu_samba/export/guitar.wav
JACK tmpdir identified as [/dev/shm]
Playing WAVE 'nuu_samba/export/guitar.wav' : Signed 16 bit Little Endian,
Rate 48000 Hz, Stereo
aplay: set_params:900: Sample format non available
Not only is it bad english [;)] but also it seems to be a regression as this
used to work perfectly fine in gutsy with libasound2 version 1.0.13..
