I don't know what happens if you use the Fedora jack package. If you have the Planet CCRMA jack package (based on jack2) the answer is yes, starting jackd will politely ask pulseaudio to release the card and jackd will be happy. When jackd exits the card is released and pulseaudio grabs it again. > If not, how can I add pulseaudio suspend (and resume) to qjackctl? In fc11 where the interface between jackd and pulseaudio had some bugs I ended up writing a perl script that would do the right thing. I'm attaching it to this email for reference. If the Fedora jack does not interface with pulseaudio you could (as root) "mv /usr/bin/jackd /usr/bin/jackd.bin" and then install the script as /usr/bin/jackd (don't forget to chmod it to 775). Of course this will "break" the rpm package of jackd so if you upgrade jackd you will need to redo the script again. > How can I tell if pulseaudio is running, is there a terminal command > for pulseaudio status? > > I have searched through the jackaudio.org, pulseaudio.org, > qjackctl.sourceforge.net and other sites, and didn't find an obvious > answer. > http://fedorasolved.org/Members/fenris02/pulseaudio-fixes-and-workarounds has some info but not about jack. You need to install pulseaudio-utils if it is not there already (BTW, you will need that for the script as well). pactl stat will tell you stuff about pulseaudio... -- Fernando
