I've not yet been able to get the Nvidia MCP61 (RealTek ALC662) onboard sound
working (EliteGroup Computer Systems) on the Athlon 64 3200+ motherboard.
A hwinfo is enclosed:

and the pastebin is http://pastebin.ca/1048637 for all the information on the
YaST2 does the typical sound card editing, and you can hear the speakers click
when the card is (de)activated. But no sound is available, even using the
speaker-test command or running alsaconf.
I've gradually worked my way up from v1.0.14 to the current v1.0.17rl1 but
have no success yet in getting the sound modules to work for the Nvidia MCP61
After posting in the install newsgroup one of the persons trying to help me
out suggested that I send a note to the developer's group for the following
reason, the /var/log/message file contains the following upon booting up
> hda_codec: Unknown model for ALC662, trying auto-probe from BIOS...
> ALSA sound/pci/hda/hda_codec.c:2333: autoconfig: line_outs=1
> ALSA sound/pci/hda/hda_codec.c:2337: speaker_outs=0 (0x0/0x0/0x0/0x0/0x0)
> ALSA sound/pci/hda/hda_codec.c:2341: hp_outs=1 (0x1b/0x0/0x0/0x0/0x0)
> ALSA sound/pci/hda/hda_codec.c:2349: inputs: mic=0x18, fmic=0x19,
> line=0x1a, fline=0x0, cd=0x0, aux=0x0
> hda_codec: num_steps = 0 for NID=0xc
And the thought was that "Unknown model" should not be occurring.
The /etc/modprobe.d/sound file has one of the allowed models for this codec.
Any ideas? Does hda_codec.c need a patch?
