I have no sound even though the system can see the sound card
i have re-installed the nvidia audio drivers but
My 'volume' icon is no longer there

i added another (different i think) volume control button but when i start it i get this message:
"No volume control GStreamer pluggins and/oor devices found"

i have just about all the GStreamer stuff installed and have searched for others mentioning volume control but can't see anything on synaptic that seems relevent

any ideas?

Thanks

extract from the install log of the driver - is this the cause?
-> The previously installed file
'/lib/modules/2.6.15-23-386/kernel/sound/oss/nvsound.ko' has a different
checksum (1577404839) than when it was installed (2562928459).
/lib/modules/2.6.15-23-386/kernel/sound/oss/nvsound.ko will not be
uninstalled.

-> done.
WARNING: Your driver installation has been altered since it was initially
installed; this may happen, for example, if you have since installed
the NVIDIA driver through a mechanism other than the
nforce-installer(such as rpm or with the NVIDIA tarballs). The
installer will attempt to uninstall as best it can. Please see the
file '/var/log/nvidia-nforce-installer.log' for details.

First thought- have you upgraded your kernel since you first installed your nvidia drivers? If so then you have to reinstall them, and if it's loading the module from the previous kernel build then you may have to rmmod nvsound before proceeding to reinstall the driver.
 
ok - having a go at reinstalling the linux header and linux image (of same version as boots from grub) - hope thats the right ones - will report back

PS - do i have anything else loaded that i shouldn't?

thanks M0KUJ1N thats fixed the sound - much appreciated

just so i can understand whats going on a bit better can you explain what order things need doing

so, if i upgrade the kernal (through Synaptic) should i (do i) need to reinstall the grapics and sound drivers?

and if i upgrade the drivers do i then need to re0install the kernal??

now that i have learned about rmmod to get rid of nvsound is there also a command to remove the graphics drivers?

many thanks

Diss
 
grrr this is so frustrating

i did have the sound working - but not the nvidia grapcs drivers

so i reinstalled the restricted linux kernal

RESULT
Nvidia Graphics work
Nvidia sound stops working!!

so i try reinstalling the audio drivers and get thsi:

ERROR: Installation of the audio driver has failed. Please see the file

suggestions on fixing installation problems in the README available on
the Linux driver download page at www.nvidia.com.

i then went into synaptic and installed linux-source 2.6.15.23.35 (to go with my 2.6.15-23-k7 kernal - is that ok?

stuck again :(
