No co się tutaj dzieje, to ja nawet nie bardzo wiem xD

speaker-test -Ddefault -c 6


Playback device is default

Gra mi na słuchawkach, które są wpięte do głośników, do tylnego panelu. Klasyk gatunku.

Tak samo oczywiście bez podania parametru

-D default
MPD zaś z takim wyjściem:

audio_output {


type "alsa"


name "ALSA 5.1"


device "default"


}

Gra mi przez HDMI na tv. I ni cholery nie chce się zmusić aby grać przez to samo default. Jeden system dźwięku, a różne defaulty ma?

Jak nakarmić mpd tym samym default który ma speaker-test?
