I installed Dapper Flight 6 but somehow my sound is not working at all! I have an MSI S 250 notebook with this SIS SI7012 device.

In Breezy the sound and the volume control worked. There was no sound from the speakers though, but when I inserted headphones I could hear the sound - only that it was very weak even at 100%.

Now my lspci looks like this:

0000:00:00.0 Host bridge: Silicon Integrated Systems [SiS] 661FX/M661FX/M661MX Host (rev 11)
0000:00:01.0 PCI bridge: Silicon Integrated Systems [SiS] SiS AGP Port (virtual PCI-to-PCI bridge)

0000:01:00.0 VGA compatible controller: Silicon Integrated Systems [SiS] 661/741/760/761 PCI/AGP VGA Display Adapter

And in the device control screen I can see that my Sound Controller is SiS SI7012.

lsmod | grep sis:

soundcore              10784  1 snd
snd_page_alloc         11304  2 snd_intel8x0,snd_pcm

Don't know if this is in gstreamer 0.10 or in the sis module, but the volume control in Gnome panel says there are no correct plugins or devices found.

I can't seem to find the Multimedia Setup from the menu (was under System in Breezy) so I'm a bit lost for the moment.
