audio problem in 10.10

[Luca Ferrari]

Hi,
my audio was working in Kubuntu 10.04 on acer aspire 6935, but after the full 
upgrade to 10.10 my audio is no more working.
The lshw shows that my audio card is:
*-multimedia
             description: Audio device
             product: 82801I (ICH9 Family) HD Audio Controller
             vendor: Intel Corporation
             physical id: 1b
             bus info: pci at 0000:00:1b.0
             version: 03
             width: 64 bits
             clock: 33MHz
             capabilities: bus_master cap_list
             configuration: driver=HDA Intel latency=0

and in the system settings talks of an internal audio analog device. Any idea?

Thanks,
Luca
