Hi Flo, I am also running Ubuntu 12.10 and using
jackdbus. It is
really nice for things like playing along to youtube videos.. On my
computer, I noticed that jack does have a tendency to lockup after a
while when jackdbus is running. I had the feeling that it might be
something to do with latency, as I found it is impossible to start
jack at very low latencies with jackdbus running. I was using 128
samples which seemed to be OK, but at that latency, the lockups
occurred after some time. I tried increasing latency to 256
samples/44.1k. Following this, it seems to operate fine (at least I
have had no more dropouts), but it is all a bit fiddly to get it to
work properly, and I would probably disable pulse if I wanted to do
serious recording etc without the mixing capabilities that jackdbus
adds.. James
I use very large period sizes, 1024 or even 2048. The problem of jackd
starting to eat 100% cpu occurs usually when I'm done with my current
work (recording something or fiddling around) and just leave it running
idly. Then when I return to my computer after a few hours jackd sits
there happily eating cpu. It has the side effect of heating my room, but
heating with electricity is expensive and thus I'd rather avoid it ;D
Have fun,
Flo
