Hello,

I can't get any sound in Kubuntu and have no idea how the sound system
actually works.

LSPCI sees the sound chip as such:

00:06.1 Audio device: nVidia Corporation MCP55 High Definition Audio
(rev a2)

It appears that programs think all the right drivers are loaded and try
to play something but no sound comes out.

I still have the Gutsy partition on another drive and tested it to be
sure that nothing was wrong with my cord or speakers. It worked there fine.

I installed over the old home partition with my home setting intact so I
thought perhaps that caused a problem but a new test user with default
hardy settings was not able to get sound either. (The new root partition
is brand new and included no old settings)

Does anybody have any troubleshooting ideas for me?

Thanks

I'm not a Kubuntu user, but in Gnome it is important to make sure that

* The PulseAudio daemon is started. In Gnome this is done through
a compatibility layer that simulates esd, and therefore the
checkbox in System > Preferences > Sound > tab Sounds > Enable
software sound mixing (ESD)
* If possible, the preferences of all apps that use sound are set
to use PulseAudio
* The user is a member of the pulseaudio* groups

Thanks, but its something lower down in the system. Apparently something
with the hda_intel driver. I disabled the onboard sound, put and old
soun blaster in and it works.
