Aver para saber cual es realente la Tarjeta de sonido q tienes abre una terminal y pon:
/sbin/lspci |grep audio
denberia dar algun resultado parecido a este:
get@tsystems-1c7591-explotacion:~$ /sbin/lspci |grep audio
00:1e.2 Multimedia audio controller: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) AC'97 Audio Controller (rev 03)
get@tsystems-1c7591-explotacion:~$
para averiguar el driver que tienes actualmente en uso:
cat /etc/modprobe.d/sound |awk '{print $3}'|head -1
get@tsystems-1c7591-explotacion:~$ cat /etc/modprobe.d/sound |awk '{print $3}'|head -1
snd-intel8x0
fijate tu si hay drivers integrados al kernel (eso si, si viene con alsa sino no.)
