I have the same problem, but I have only one soundcard: Soundblaster Audigy ZS 2.
When I start qjackctl (without starting jackd yet!) there is no more sound from applications like totem or system sounds. Totem just stops at the current position. When I left-click the speaker Icon in the upper right corner and go to settings, hardware, I can select a Profile. When I switch that profile from "Analog Stereo Output" to "IEC958" or the other way, sound works again. It does not matter what is selected before starting qjackctl, I simply have to change the setting. When I start qjackctl and then jackd and initiate suspend to ram (S3), jackd ist stopped after resuming from standby. qjackctl still runs. I start jackd and both audio from jackd and pulseadio is working fine. I see the problem somewhere in qjackctl. At startup it does something to pulseaudio or the soudcard, even without starting jackd. Maybe it scans for available outputs/inputs then... ? -- pulse audio stop when qjackctl is launched https://bugs.launchpad.net/bugs/231601 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
