This message originally posted to ardour-users-ardour. I received two
replies and tried to answer them from mutt. My answers never appeared
in the list or the archive.
I have installed alsa, patched a 2.4.22 kernel with preempt and
lowlatency, compiled the kernel with Sound Card Support, Creative
SBLive! and OSS Sound modules as modules, set kernel.lowlatency=1 and
copied asoundrc to ~/.asoundrc, opened a terminal in the X display,
switched to root and entered jackd -R -d alsa - sblive.
jackd aborts with the message:"pcm.c:690: snd_pcm_nonblock: Assertion
'pcm' failed."
What am I missing?

Philcorda asked: What's in .asoundrc?
Answer:
pcm.sblive {
type hw
card 0
}
pcm.ctl {
type hw
card 0
}
Philcordia asked: Is ARTS or esound running?
Answer: I don't believe so. top shows only one active file, top itself.
Philcordia asked: Have you tried jack with -S or -P? Does jackd without
-d sblive do anything?
Answer: When I started jack it wanted to rip a cd. jackd -R -d alsa
and jackd -R -d alsa -d hw:0 give the same result as above.
Philcordia asked: Maybe some stale temporary files. Where did you
configure jact?
Answer: I didn't. I used apt-get install jackd to get the debian
package and read user-howto.gz. There is no mention of configuration or
temporary files and I cannot locate jact in my system.
A final note: My objective is to capture input from my phonograph,
remove cracks and clicks and write the result to a cd. The phonograph
input is to the sblive card, the output from the card is to my stereo
system.
