Bug Description
Hi,
I've just installed Ubuntu Dapper on my new Vaio SZ110.
I've seen similar bugs in the database but this one seems to apply to the SigmaTel codec.
Everything loads fine, all the modules seems to be installed successfully. Alsa mixer reports only one channel called PCM, nothing else. This channel is unmuted and the volume at its maximum. But still, there is no sound at all.
The gnome volume controller reports the same thing.
This laptop model came out very recently.
Here is all the information regarding my machine that i thought could be relevant to this bug.

There is current (low-priority) work to merge the necessary HDA changes for another codec from upstream, so the necessary bits to fiddle for your hardware may be updated coincidentally, but it looks like your hardware may be too new to support in time for Dapper. Dapper+1 is definite.
