Re: Dźwięk 5.1 i mplayer
Kłopotów z dźwiękiem 5.1 pod mplayerem ciąg dalszy.
Polecenie
Kod:
speaker-test -Dplug:surround51 -c6 -twav
daje prawidłowy test.
Użycie mplayera do oglądania filmu z dźwiękiem 5.1 z opcją w configu
Kod:
ao=alsa
powoduje permanentne zacinanie się dźwięku i obrazu. Z kolei przy opcji
Kod:
ao=oss
zniekształceń i opóźnień nie ma, natomiast mplayer przestawia kolejność kanałów. Na przykład centralny jest w lewym tylnym.

Nic co by miało związek z dźwiękiem. Myślę, że to jednak bardziej dotyczy konfiguracji karty niż mplayera.
