Hi all,

Last night, or was it the night before, I did quite a big update which required a restart. Since then I haven't had sound and intermittently the screen tends to go a pale grey and loses all colour. In that grey condition few buttons respond. After a couple of minutes it comes back and seems to behave itself for another five minutes or so before going through the grey cycle again.

I've just been through synaptic to ask for upgrades which have been installed.

Turning back to the sound I found nothing listed in Hardware and Output offering just a Dummy - but in stereo!! Previously I had the onboard stereo and HDMI on offer. (Not that I could get the HDMI to work with my tele).

So inputting to Terminal cat /proc/asound/version tells me I have
Advanced Linux Sound Architecture Driver Version 1.0.23.
Compiled on Aug 26 2010 for kernel 2.6.32-24-generic (SMP).

Any and all ideas gratefully accepted.

regards,

brawd.

It's nothing that makes sense to me but I hope it helps.

Ok all resolved - for the present.

I re-installed the Alsa drivers from here

http://monespaceperso.org/blog-en/2010/05/02/upgrade-alsa-1-0-23-on-ubuntu-lucid-lynx-10-04/

and life is once again a bowl of cherries.

regards,

brawd.
