I downloaded the Knoppix 5.0.1 CD English version and discovered that during the boot process my sound system is not activated. I can get it to work by manually going through the "alsaconf" process.
Here is an excerpt of the lspci comand after booting is complete:
0000:00:1b.0 0403: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 01)
Subsystem: Intel Corporation: Unknown device 0202
Flags: bus master, fast devsel, latency 0, IRQ 22

Capabilities: [60] Message Signalled Interrupts: 64bit+ Queue=0/0 Enable-

Any suggestions?
Thanks
