Dotaz: PCSPEAKER

[pepe_]

Zdravim , občas se mi při spuštění pc stane že alsa nahlásí chybu a místo aby zvuk přehrávala zvuková karta tak zvuk hraje skrze pcspeaker. Zde je LSMOD :

Takže je jasné že jako výchozí dá PCSPEAKER , ale ne vždy , jen 1x za cca 15 startů.

zkoušel sem podle návodu na  https://help.ubuntu.com/community/SoundTroubleshooting

vytvořit /etc/modprobe.d/alsa-base a do něj dát

 

options snd_intel8x0 index=0
options snd_intel8x0m index=1
options snd_pcsp index=2

 

ale žádná změna , občas stále je výchozí pcspeaker

Napadá Vás něco ?

[petr_p]

Nejjednodušší je zbavit se modulu snd_pcsp. Taky by šlo pohrát si s aliasy v /etc/modprobe.d/alsa, abyste si zajistil. Ale mám dojem, že ALSA je v tomhle směru natvrdlá.

[dustin]

To pořadí mi vždy fungovalo. Pochopil jsem správně dle uname -a, že jde o arch? Pak by ubuntí postupy nemusely fungovat, je otázkou, zda se ta konfigurace v /etc/modprobe.d vůbec načítá. Pokud existuje /etc/modprobe.conf, zkusil bych to dát tam. Jinak možná ještě lepší by bylo dát snd_pcspk na blacklist, aby se vůbec nenatahoval. Nebo natvrdo smazat z /lib/modules, ale to je ošklivý hack.

To samé bych udělal s tím modulem pro modem snd_intel8x0m, pokud jej nepoužíváš.

[petr_p]

Podle modprobe.conf(5) se nejprve načítá /etc/modprobe.conf a když neexistuje, tak /etc/modprobe.d/*. Některé distribuce (Debian/testing) už od generování /etc/modprobe.conf upouštějí.

[dustin]

Jen nevím, zda je takto nakonfigurovaný modprobe i na archu.

[mikky]

Pokud Speaker nepotřebuješ vůbec, tak nejjednodušší (a nejčistější) způsob, jak v Archu Speaker zrušit je upravit pole MODULES v /etc/rc.conf:

MODULES=(... !snd_pcsp ...)

Vykřičník zařídí umístění modulu na blacklist.
