Does anyone
else get clicks which occur continuously after getting a
single xrun in jack? (i.e no further xruns are reported, but the audio
is
crackling).
Dave, when I've seen this before its generally been a hardware issue,
typically something stealing the PCI bus for too long. However, if the
same thing doesn't happen with, say, aplay, then there is more
investigation to be done. Step one would be to run aplay with the -v
command, and then use the info to set up JACK with identical h/w
parameters.
Ok, I have some better information now...
aplay works fine - no glitches
jack with the same parameters - testing with jack_metro to get my stuff
out of the loop, glitches.
This is on a ALC888 - which has surround support with 8 output channels
(which I don't actually need).
The glitches only happen when there is a signal - and sounds to me like
something is being set to 0 at the beginning/end of the buffer (the
frequency changes if I change the buffer size).
Cheers,
dave
