soundcard

Sound on my computer was working fine under 12.04 however when I upgraded to 12.10 I have encounter a strange problem where when I switch users instead of the first user having its sound swamped the sound of the first user keep playing and the second user can not play and thing. The sound setting for the second user only show a Dummy Output. If I reboot and log into the second user sound works fine but then if you switch to the first user it has a dummy output instead.

What could would cause such a problem?

This has meant in the past that I had to rely on a custom iso to install… >>> More

Looking at https://wiki.ubuntu.com/Releases 13.04 will reach EOL in January 2014, while 12.10 will reach EOL in April 2014, therefore if a 12.10 user hasn't upgraded to 13.04 and subsequently to 13.10, there will be a 3 month period where a 12.10 user has a supported version of Ubuntu, but will be… >>> More
