poglej, da ti v ozadju ne teče kakšen programček za nastavljanje glasnosti
ali kašnen mikser...
mislim da sem imel enkrat takšen problem z open-soundom...

lep dan

	Pozdravljeni!

Na Linuxu imam v kernel nalozen nek modul, ki bi ga rad odstranil, vendar
z rmmod to ne gre, saj se le ta pritozi, da je modul v uporabi, ceprav ni,
oz. vsaj ne bi smel biti. Imam kdo kaksno idejo, kako tak modul vendarle
odstraniti? fuser, lsof in ps ne pokazejo nic uporabnega.

lsmod ipise:

Problematicen je modul snd-ens1371. Gre za ALSA driver za Creative Ensoniq
AudioPCI. Uporabljam kernel 2.4.21-rc2 in ALSA driverje 0.9.3a.

Modul bi rad odstranil, ker mi vsi programi, ki bi radi na zvocno kartico
poslali kak zvok, cakajo, da se bo domnevno zasedena zvocna kartica
sprostila. Zadnje uspesno predvajanje zvoka je bil (prvi in edini) zagon
alsaplayer-ja. Po tem zagonu se je v dmesg pojavilo:

Ali se je ta alsaplayer kot tak uspesno zakljucil, ali sem ga sam prekinil
sredi dela ali pa se je sesul, zal ne bi vedel.

Ima kdo kaksno idejo, kako problem resiti brez reboota?

Lep pozdrav,
		Ales
