Can Reaper or Jack allow all audio @ same time in Linux

[hapibeli]

I am very happy that I now can listen to either Reaper or other sources, but NOT at the same time, as I must shut Reaper down to hear any other audio from my machine.

OK, so turning on Jack, I can hear Reaper. Turning off Jack, I can hear any other source. Not greay, but better than having to `shutdown programs.

Yeh I had this problem a while back and I finally got it solved one day when I installed Cadence. It's not that you need Cadence to do it, it just makes it nice and easy.

My settings in Cadence under 'Jack bridges'

ALSA Audio: ALSA>PulseAudio>Jack plugin
ALSA MIDI: Bridge running
PulseAudio: Stared and bridged to Jack

I've also ticked to boxes to auto-start these things at login.

I don't have to stop and start Jack anymore, I can just leave it running all the time whatever I'm doing.

It's even simpler with Cadence. Simply run 'cadence-pulse2jack' when jack is running.

Ah yeh I forgot. Make sure these are installed:

jackd2
pulseaudio-module-jack
aj2mid

If I'm not mistaken, the second one will allow you to bridge PulseAudio through Jack and the third one will allow you to do the same with midi. They'll probably come up as optional dependencies if you install Cadence via your package manager so just select them if so.

I used Cadence for a while but prefer QJackCtl. Your graph doesn't show the PulseAudio JACK Sink. Do you actually have pulseaudio-module-jack installed?
Your command in QJackCtl should load the module but it isn't. I use a simpler command as I never need the source module which is only to record JACK output in PA (does anyone ever do that?). a2jmidid is for JACK to see a MIDI keyboard. With this setup I can play audio through PA simultaneously with Mixbus via JACK (don't need to do that either but saves switching manually). Reaper should be the same.
This is the command I use:

Code: Select all

pactl load-module module-jack-sink channels=2 && a2jmidid -e &

And what the graph looks like:
