[RiminiLUG-General] Re: nVidia HDMI senza audio

Dopo l'incontro di ieri sera, l'audio tramite HDMI sul portatile
funziona (grazie Samu).
Però non sono riuscito a farlo funzionare sul PC attaccato alla TV,
quello con la scheda nVidia GT440.
Vi riporto l'output di alcuni comandi sperando che a voi dicano
qualcosa in più. Pulseaudio non risulta installato.
Ricordo che sto lavorando su una mythbuntu con xfce

$ speaker-test -D hdmi -c 2
speaker-test 1.0.24.2

Playback device is hdmi
Stream parameters are 48000Hz, S16_LE, 2 channels
Using 16 octaves of pink noise
Playback open error: -2,No such file or directory
