[KDE] przełączanie pomiędzy urządzeniami odtwarzającymi skrótem

Potrzebuję skryptu, dzięki któremu będę mógł się przełączać skrótem klawiatury między urządzeniami odtwarzającymi, tj. dwoma kartami dźwiękowymi Intel i Cube. Kontroluję głośność Master channel skrótami, ale to obsługuje poziom głośności tylko bieżącego urządzenia odtwarzającego.
Znalazłem jakieś skrypty, ale nie bardzo wiem jak je zastosować i czy mają one zastosowanie do kmix.

Re: [KDE] przełączanie pomiędzy urządzeniami odtwarzającymi skrótem

Możesz pokombinować z podmienianiem ~/.asoundrc

https://forum.dug.net.pl/viewtopic.php?id=18662

Ale nie wiem czy to zadziała z pulseaudio i phononem.

Re: [KDE] przełączanie pomiędzy urządzeniami odtwarzającymi skrótem

Poza [i]~/.asoundrc[/i] można podmieniać zawartość [i]~/.config/kde.org/libphonon.conf[/i] lub [i]~/.kde/share/config/phonondevicesrc[/i]
Pulseaudio też ma swoje pliki konfiguracyjne i da się w taki sam sposób to przełączać.

Masz więc trzy całkiem proste sposoby.
