Comment 55 for bug 131133

to check what audio chipset you have run:

     lspci | grep -i audio

then check the nn:mm.x number at the start of the line. Then

    lspci -n | grep nn.mm.x

The third number is the PCI (chipset) id.

E.g. for the chip set of this bug report: 8086:284b. Like

00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 02)

and

00:1b.0 0403: 8086:284b (rev 02)
