[Rafael & Matthew: this is a resend - original was sent to wrong linux-kernel address. Also updated, so just ignore the earlier emails.]

With 2.6.25-git I lost sound on my Dell XPS M1330 laptop. There seems to be two issues at hand here: 1. Analog output is listed, but emits no sound (just silence), and 2. Digital out device is missing.

Issue #1 is bisected in this thread. #2 is still work in progress, and will be posted as a separate thread.

git bisect nailed down the missing audio issue to this commit:
2f32d909f3a85a96074801f6cf20f93324f87646 is first bad commit

[ALSA] hda: STAC9228 VT fixes

Moved 2 systems PCI_QUIRK values to STAC_DELL_BIOS. Also the second
front HP jack is incorrect defined in the BIOS VT's for some laptops,
this patch corrects this.
