Bug v jadre.

Ako sa da tomu predist, alebo ci je moznost pouzivat namiesto ALSA nejaky iny ovladac, modul. Cize problemov sa zbavim vtedy ak zvuk vypnem? Skusal som uz niekolko kernelov stale to iste. Ak ini maju vsetko ok. Co s tym budeme robit?

[R]

Ake jadro tam mas? Ak to robi aj najnovsie, tak by to chcelo bug oznamit.

[cyclope]

my s tim nebudeme robit nic to musis ty

jinak, ja mel problemy se zvukovkou na novem NB (z hlavy nevim, jaka byla) ve slackware s jadrem 2.6.21-5 pomohlo mi stahnout, zkomilovat a zavest modul alsa-driver z teto adresy - cokoli nad verzi 1.0.6

mozna to pomuze, me to pomohlo

[dustin]

A i přes ty hlášky zvuk funguje, nebo ne?

[frEon]

doporucuju zkompilovat si moduly primo z alsa-project.org. V jadre je vetsinou starsi verze alsy nez aktualni a tim padem je sance, ze uz to je opravene. Samozdrejme nahlasit problem novelu taky neni spatny napad.
