SOLVED:onboard nvidia sound not working

[drgb]

I just upgraded from kubuntu gutsy to hardy on my amd 64 x2 machine, and am not getting any onboard sound. The sound card seems to be detected in lspci:

00:10.1 Audio device: nVidia Corporation MCP51 High Definition Audio (rev a2)
Subsystem: Hewlett-Packard Company Unknown device 2a34
Flags: bus master, 66MHz, fast devsel, latency 0, IRQ 22
Memory at fe024000 (32-bit, non-prefetchable) [size=16K]
Capabilities: [44] Power Management version 2
Capabilities: [50] Message Signalled Interrupts: Mask+ 64bit+ Queue=0/0 Enable-
Capabilities: [6c] HyperTransport: MSI Mapping

yes, I unmuted and upped master sound level in kmix, hoping to hear something, but no go.
any help would be much appreciated.

This is pretty much the gold standard for sound troubleshooting:

You may want to check on the ACH (optical audio, aka ice95x) switch being set or not. I had a bear of a time once long ago where it was defaulting to that.

I would also try a non-gui program, such as mpg123, to make sure it's not running through xine or gstreamer, as one of those programs may have a configuration issue.

Is the /dev/audio file being created?

Re: onboard nvidia sound not working

thanks you dibl.
the step that did it was adding the sound driver name 'snd-hda-intel' to the end of my /etc/modules file. the sound driver was there but not being loaded.

now to get my emu 0404 pci sound working...
