Ciao. Non riesco a sentire l'audio... Ho provato a configurarlo con "alsaconf" e mi ha detto che la mia scheda audio è stata configurata correttamente, poi dopo però se provo a regolare il volume con alsamixer mi da errore

Code:

# alsamixer

alsamixer: function snd_ctl_open failed for default: No such device

Non ne sono certo, ma la tua scheda dovrebbe essere supportata dal relativo modulo presente nel kernel.
Hai provato a seguire la seguente guida: http://www.gentoo.org/doc/it/alsa-guide.xml.
In particolare verifica di aver attivato questo modulo nel kernel:
Code:
  │ Symbol: SND_INTEL8X0 [=n]                                                                                                                                                                                   │ 
  │ Prompt: Intel/SiS/nVidia/AMD/ALi AC97 Controller                                                                                                                                                            │ 
  │   Defined at sound/pci/Kconfig:552                                                                                                                                                                          │ 
  │   Depends on: HAS_IOMEM && !M68K && SOUND!=n && PCI && SND                                                                                                                                                  │ 
  │   Location:                                                                                                                                                                                                 │ 
  │     -> Device Drivers                                                                                                                                                                                       │ 
  │       -> Sound                                                                                                                                                                                              │ 
  │         -> Advanced Linux Sound Architecture                                                                                                                                                                │ 
  │           -> Advanced Linux Sound Architecture (SND [=y])                                                                                                                                                   │ 
  │             -> PCI devices                                                                                                                                                                                  │
