#jackd — Public Fediverse posts

I switched from #pulseaudio to #pipewire some weeks ago.
Now I need to found out how to make jackd-applications (#Hydrogen, #Ardour mostly but some others as well in the future) work, and it seems not an easy task.
(Yes I know pipewire-jack and qpwgraph exists and I'm looking at those right now)

#debian #linux #music #MAO #jackd

#No, I love linux audio

# is the ultra attached
if aplay -l | grep -qi ultra
then
echo ultra

#adjust amplitude
i=0
j=0
for i in $(seq 8); do
for j in $(seq 8); do
if [ "$i" != "$j" ]; then
amixer -c Ultra set "DIn$i - Out$j" 0% > /dev/null
#amixer -c Ultra set "DIn$i - Out$j" 100% > /dev/null
else
amixer -c Ultra set "DIn$i - Out$j" 100% > /dev/null
fi
amixer -c Ultra set "AIn$i - Out$j" 0% > /dev/null
#amixer -c Ultra set "AIn$i - Out$j" 100% > /dev/null
done
done

for i in $(seq 4); do
amixer -c Ultra set "Effect Return $i" 0% > /dev/null
done

#start jack
#jackd -d alsa -d hw:Ultra -r 48000 -p 2048 &
#else
#start jack with default hardware
#jackd -d alsa -d hw:PCH -r 48000 &
fi

finally I was able to make #jackd work together with #pulseaudio
I took me ages to figure this out. So now pa adds the jack sink whenever jack is started and I can continue to hear sound from pa applications.
The trick is that you need to start jackd via dbus then everything works autmagically in #debian.
the necessary option in #qjackctl in the image...
