I am having trouble getting alsa and jackd to work on Fedora14. I have had this working on a much older version.
I have disabled pulseaudio by removing the rpm (I hope this is enough).
My .asoundrc file looks like this:
# use this as default
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
}
}
I run jackd and get this:
jackdmp 1.9.5

aplay: pcm_write:1603: write error: Input/output error
while jackd gives:
Unknown destination port in attempted (dis)connection src_name [alsa-jack.jackP.29854.0:out_000] dst_name [alsa_pcm:playback_1]
Without jack, the wav file plays fine an alsamixer works. It looks like jackd doesn't know how to talk to alsa but it has read the .asoundrc file.
I have the following installed:
qjackctl-0.3.8-1.fc14.i686
jack-audio-connection-kit-1.9.5-1.fc14.i686
alsa-plugins-jack-1.0.22-1.fc13.i686
jack_capture-0.9.56-1.fc14.1.i686
Any help appreciated.
