Сменил недавно мать, на новой матери звук встроенный - Realtek ALC681VD на ICH7 High Definition Audio Controller. ось - Debian Sid. с альсой копался, но не смог даже просто 5.1 звук в шестиканальных фильмах поднять, под OSS 5.1 работает только при шестиканальном исходном звуке, то есть микширование на каналы почему-то не работает, хотя vmix отмечен, как многоканальный . При osstest работают все колонки. вывод ossinfo -v3 :
