Unfortunately, I'm not getting any sound at all (other than hiss). The 
output of lspci -v is:

0000:00:0b.0 Multimedia audio controller: Creative Labs SB Audigy LS
        Subsystem: Creative Labs: Unknown device 100a
        Flags: bus master, medium devsel, latency 64, IRQ 11
        I/O ports at d400 [size=32]
        Capabilities: [dc] Power Management version 2

Can you give me a clue where I find the chipset/driver info?

many thanks...

David.
