Description Michał Zegan 2015-08-15 18:19:02 UTC

Hello.

When jackdbus starts and takes card from pulseaudio, pulseaudio suspends the card, and then sinks/sources are loaded.
It would be very useful if after that happened, all applications using the taken card would automatically switch to jack sources/sinks.
This would be very useful in case of people that are for example blind, require sound card to use a computer, but do not use a separate card for jack for any reason.

those pulseaudio client can only connect to pulseaudio server

it is unlikely to change all application to use jackd instead of pulseaudio

as pulseaudio server is still running but only release one card to jackd


if pulseaudio can be start and shutdown by systemd as a service, this mean pulseaudio should not auto spwan

Actually pulseaudio itself adds jack sink/source when jack takes the card, but the original (taken) card is suspended and applications connected to pulseaudio previously routed to the original card are not switched to jack sink/source

you have to provide pulseaudio verbose log to show how jackdbus request pulseaudio to release the card when other application is still using the card

your jackd server need to open the card exclusively when pulseaudio is not using the card
