This old ThinkPad T22 just keeps ticking. I just upgraded to Ubuntu 10.04 from Hardy Haron on my daughters laptop and all seems fine except the sound. No sound. No mic either it seems. Both are on board.

I did an online upgrade and may have answered some questions about hardware incorrectly during the initial build.

Can anyone guide me with advice. I'm not very good at the technical parts of Ubuntu but I absolutely love it...especially for the kids.
IE. Please do step by step.

Thanks

I had the same problem, the solution is simple, go back to 9.04.
There is a big lack of supported hardware specially older audio hardware like on the T22.
Besides 9.04 runs faster then 10.04 on the Thinkpad, still use a T22 for email stuff.

Why to go back? Here it is the solution,already worked for me in Ubuntu 9.10 and ubuntu 10.04

Ubuntu 9.04 works out of the box on a Thinkpad, secondly why install a version that needs tinkering and that is to big and to modern for an old piece of hardware anyway.
You are right about to install Alsa, this is a more sensible thing to do anyway, purge the pulseaudio crap and use alsa and oss in compatible-mode, some games expect oss as backend.
Ubuntu made some wrong decisions in versions after 9.04 the evidence is the number of forums about not functioning hardware.
So my opinion was and reason to go back to 9.04 is;
1. It works out of the box, no tinkering required.
2. Stable, 9.04 is more stable and compatible on older hardware.
3. later versions use edev by default, you need to tamper xorg.conf (touchpad, DPMS, sleep issues).

And most important of all we don't want the daughter of S. to turn her back on Linux and turn her to the "Redmond Syndicate".
