No onboard sound after upgrading to hardy

04-27-2008, 01:12 AM

I just upgraded from kubuntu gutsy to hardy on my amd 64 x2 machine,
and am not getting any onboard sound. the sound worked in Gutsy. 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.
artsd sound server is running as expected.
any help would be much appreciated.

thanks

This may or may not be a solution, but it should be mentioned.

I installed kubuntu on an IBM laptop that previously ran gutsy just fine.

The sound wasn't working and I couldn't get the wireless working.

I added the wireless modules into /etc/initramfs/modules and then ran

update-initramfs thinking that if the modules were available at boot time,
the wireless card would be seen.... but it appeared that it was already seen
at boot so I didn't have much expectation of fixing anything.

I rebooted, and low and behold I had both sound and wireless.

Methinks there might be something wrong with the distributed initrd.

It wouldn't hurt to make a copy of your current initrd file and then run:

update-initramfs -k all -c

which will create a new initrd file. Then reboot.

The following refers to some Dell laptops but it might give you a starter at troubleshooting:

Hi

By just looking at the output of lspci will not tell you if drivers
have been loaded or
working. Better then to check the output of /proc/asound/cards (think it's that)
to see what soundcards has been recongised and drivers loaded for.

The command lsmod will show you what modules has been loaded. The driver
for your card i think is snd-hda-intel, see if that is loaded.

Another very helpful command is the hwinfo command.

hwinfo --sound would show you something like:

Note at the bottom it shows you the driver needed and whether it is active or
not.

All: The step that solved this no sound problem 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.
thanks to others for data on lsmod and hwinfo.
Now to get sound working in my emu 0404 pci sound Card!

Thanks,

Geoffrey Bays
