Grazie per esserti interessato al mio problema ma nonostante le tue indicazioni l'audio latita. C'è un'unica differenza su yast che mi da questo output dalla configurazione audio:

indice | modello

HDA intel

non configurato 82801H(ICH8 family) HD audio controller

...e provando a configurare la prima voce, semplicemente svanisce la finestra, mentre, configurando la seconda mi viene restituito questo messa ggio: il modulo del kernel snd-hda-intel per il suono non può essere caricato. Questo potrebbe essere causato da parametri errati per il modulo, tra cui IO o IRQ non validi.

il comando rpm -qa|grep alsa mi restituisce questo output

alsa-tools-1.0.16.hg20080122-7.4
alsa-firmware-1.0.16.hg20080206-1.1
alsa-utils-1.0.16.hg20080212-1.3
alsa-1.0.16.hg20080219-1.1
alsa-oss-1.0.15-2.1
alsa-devel-1.0.14-31.2
alsa-driver-kmp-default-1.0.16.hg20080221_2.6.22.5_31-1.1
gmerlin-alsamixer-0.3.7-0.pm.1
alsa-plugins-1.0.16.hg20080122-5.1

il file /etc/modprobe.d/sound si presenta così

alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-hda-intel
options snd-hda-intel model=asus

E' tutto, almeno credo, dimenticavo kmixer,quando provo a configurare la seconda voce da yast, scompare.
ciao.

Provato ma non funziona. Sono tutti verde chiaro e non c'è la sbarra del mute sull'icona de mixer, quindi niente.
Ciao.

Ecco il listato del primo comando

snd_pcm_oss 50560 0
snd_mixer_oss 20352 1 snd_pcm_oss
snd_seq 55348 0
snd_seq_device 12044 1 snd_seq
snd_hda_intel 341532 1
snd_pcm 81028 2 snd_pcm_oss,snd_hda_intel
snd_timer 26756 2 snd_seq,snd_pcm
snd_page_alloc 14472 2 snd_hda_intel,snd_pcm
snd_hwdep 13316 1 snd_hda_intel
snd 63932 10 snd_pcm_oss,snd_mixer_oss,snd_seq,snd_seq_device,snd_hda_intel,snd_pcm,snd_timer,snd_hwdep
soundcore 11460 1 snd

per il secodo, fuse /dev/dsp... nessun output
Ciao.

ecco il contenuto del file che mi hai indicato, te lo listo tutto, io non ci capisco un' H,
Ciao e grazie per l'interese

Scusami Alfio, comunque l'output del comando indica che gli alsa sono caricati e in esecuzione

ALSA sound driver loaded. running
