In Traction

When I the installed Ubuntu Dapper testing releases, my sound card didn’t work anymore. It is a HDA Intel card, part of the Dell Dimension 5100 computer I use at work. The card was recognized but the volume seemed to be muted. The master and PCM channels were all maximized though.

I thought this problem was going to be fixed in the final release, but when Dapper was released my sound was still muted.

Today I came across a bug report describing the same problem and a solution.

It appears the surround control was muted, which caused everything to be muted as well.

So after also showing the surround control, and unmuting it in the Gnome volume control, my problem was fixed:

I hope this is useful for people who experienced the same problem.

Edit: apparantly this also fixes the sound problem on Macbook Pro laptops.
