Ubuntu – Jack and pulseaudio

jackpulseaudiosound

I want to run pulseaudio from startup to deal with system sounds etc and be able to run jack from qjackctl for use with audio applications (LMMS, ardour, rosegarden etc) I'm having issues when i start up, the sound applet does not allow me to control the volume. When I click sound preferences it says "waiting for sound system to respond" yet the sound still plays in rhythmbox etc.

This might not be the correct answer, but I'd recommend bringing up JACK only when you need it. Otherwise, things can get crazy with sound.

The best option I found at the moment is suspending pulseaudio while jack is running. It's described in the pulseaudio and jack page, and involves invoking the jack server through pasuspender.

From the man pages:

   pasuspender is a tool that can be used to tell a local PulseAudio sound
   server to temporarily suspend access to the  audio  devices,  to  allow
   other  applications  access  them  directly.  pasuspender  will suspend
   access to the audio devices, fork a child process, and when  the  child
   process terminates, resume access again.

To let Jack and PulseAudio work together better, you should use pasuspender.

With the options -m alsa -a alsa, amsynth should not use Jack. (You can the use aconnect to connect the keyboard to the synth.)
