Having bitten the bug I have finally parted company with my last copy of Ms windows and installed Mint-6 [full version]. Beautiful piece of kit that does everything that I need to do on the laptop right out of the box. However it has one fault, the sound is dreadful. It is definitely sounding like the mythical strangled cat. Sounds delayed slurred and is unusable. I am running a Toshiba Satellite that had no problem whatsoever running sound from its previous incarnation running Ubuntu Dapper or indeed has no problem running from Kubuntu 8.04 "Hardy" which I have just run in "live CD" mode to test the machine sound system.
I have had a little meddle with the various settings via the sound and video links within the installed MInt menu with no success and have returned them to their original settings. Here however is the interesting bit! Thinking that I had maybe screwed up the download and install, I ran the LX mag copy of Mint-6 as a live CD and have exactly the same problem with the professionally produced copy. Any and all assistance/suggestions will be very welcome.
Incidentally Mint picked up the home network without any intervention, the first Linux distro to do so among the five that I have tried.
