hello,

This worked fine in 2.6.23 but now the kernel no longer sees my audio 
controller.

00:10.1 Audio device: nVidia Corporation MCP51 High Definition Audio (rev 
a2)
00:10.1 0403: 10de:026c (rev a2)

Let me know if I can provide more info or test patches.

	Gerhard

Please provide the output of `dmesg -s 1000000' for both 2.6.23
and 2.6.24-rc3, thanks.

Are you sure that the driver is suitably configured?  Sometimes
we like to fiddle config options so that a `make oldconfig' will go and
unconfigure drivers which you need.

Found an option for generic HD audio and enabled that with only marginally 
better results.  Now instead of not detecting my card it's showing a 
single volume control in the mixer and not providing any sound at all.

Both look OK.

Please show your kernel config and /proc/asound/card0/codec#*
contents.  Did you choose CONFIG_SND_HDA_CODEC_* properly?

Also, please be more specific about your hardware.  The implementation
of HD-audio stuff is deifferent greatly among products.  It's very
important to know what kind of machine (h/w vendor, product name,
model, etc) to identify whether the configuration is known or not
(i.e. it was really supported or it worked just casually).

The machine is an Asus M2NPV-VM motherboard with an Nforce MCP51 chpset. 
and there is not an CONFIG_SND_HDA_CODEC_ option for NVIDIA so I selected 
generic instead.

Pci info:
00:10.1 Audio device: nVidia Corporation MCP51 High Definition 
Audio (rev a2)
00:10.1 0403: 10de:026c (rev a2)

That's the problem.   MCP51 is the controller chip, not a codec chip.
It's always supported by snd-hda-intel driver.  CONFIG_SND_HDA_CODEC_*
are configs to choose codec chips.

Simply select all CONFIG_SND_HDA_CODEC_*=y if you are not sure (as
they are default=y).  I guess CONFIG_SND_HDA_CODEC_ANALOG=y should
suffice but selecting others won't hurt except for a small memory
footprint.

Codec: Analog Devices AD1986A

Works like a charm now,

 thanks.
