Hello,

Using ALSA modules shipped with Linux 2.6.20, I find that with a HP
dc7600 workstation I need to load snd-hda-intel with model=basic or
model=hp or there is no sound. Alsamixer indicates Chip: Realtek ALC260.

00:1b.0 0403: 8086:27d8 (rev 01)
        Subsystem: 103c:3010

This system is in the latest driver, 1.0.14rc3.

Same with a Lenovo M55 8811, except I seem to need model=laptop.
alsamixer indicates Chip: Analog Devices AD1986A.

Try this patch and report back if it works.

You can get alsa-driver-1.0.14rc3.tar.bz2 from ftp://ftp.alsa-project.org/pub/testing/alsa-driver-1.0.14rc3.tar.bz2

If this patch works, then here's my summary in advance:

Summary: Add support for Lenovo M55 Laptop
This patch adds support for the Lenovo M55 Laptop to the HDA drivers.
