Z reguły po przełączaniu systemu (na wina) muszę wchodzić w alsamixer i likwidować podświetlenie przy przełączniku S/PDIF, w przeciwnym wypadku nie mam dźwięku. Jednak po ostatniej aktualizacji systemu (testing) po wpisaniu alsamixer w terminalu wyrzuca mi "Naruszenie ochrony pamięci" :]
Pytanie jest czy można spoza mixera przestawić ten przełącznik i czy można zmusić system by mi tego przełącznika przy restarcie nie załączał?

Mozna uzyć tekstowego amixer.
Wtedy dodasz sobie polecenie do przełączenia tego przełącznika do autostartu np środowiska graficznego

Tu masz conieco o użyciu amixer:

Praktycznie wszystko jest w man'ie. Z tym, że coś nie mogę namierzyć tego przełącznika.
tak wygląda rozpis:

Na necie piszą by przełączyć IEC958 Playback Switch tylko, że ja nic tutaj takiego nie widzę :]

Wgrałem alsę z sida i przestało wyrzucać błęda o naruszeniu pamięci. Nie wiem czemu ale zresetowały mi się wszystkie ustawienia mixera ale to marginalna sprawa. W każdym razie sam przełącznik był pod:
amixer -c 0 set IEC958 mute
