Woups! Sorry for confusing things. I guess some messages in the conversation regarding this bug gave me the impression that it was Jack related. :-|
It seems that bug is solved now. Yay! I'll try to increase the timeout to see if it helps me with my Jack issue. Still I think it's a bit odd that Mixxx is kicked when nozombies is used. I've never seen that with other clients, not even softsynths using most cpu, causing loads of xruns. //Anders 2010/6/1 Albert Santoni <albe...@mixxx.org>: > Anders: The bug the bounty is related to only involves problems when > you pick ALSA as the Sound API in Mixxx. > > If you're seeing problems with the JACK or PortAudio watchdog giving > Mixxx the boot, try running jackd with the --timeout 10000 flag. > > (I usually compile PortAudio with --prefix=/usr, and it overwrites the > old version from the Ubuntu repo.) > > Thanks, > Albert > > On Mon, May 31, 2010 at 3:02 PM, Anders Gunnarsson <d00g...@gmail.com> wrote: >> I just want to check a few things to make sure I got everything right >> regarding this issue. >> >> If I build PortAudio from source.
