One suggestion about the spin
Since it's KDE, there is no need to use pulseaudio. One elegant
alternative would be to exclude pulseaudio and include alsa-jack-plugin
providing a system wide alsa configuration (/etc/asound.conf) like this:
pcm.rawjack {
type jack
playback_ports {
0 system:playback_1
1 system:playback_2
}
capture_ports {
0 system:capture_1
1 system:capture_2
}
}
pcm.jack {
type plug
slave { pcm "rawjack" }
hint {
description "JACK Audio Connection Kit"
}
}
pcm.!default {
type plug
slave { pcm "rawjack" }
}
