Installed on my Thinkpad T61. The Intel-HDA module is correctly loaded. As has been the case with Zenwalk and Vector, I have to fiddle with the controls in order to get audio to work. Under Xfce, I have to open the mixer, which then reports 'no controls selected'. I select master, pcm, headphones, speakers. I then have to use the 'Switches' tab in the mixer. At this point, the headphone switch is ticked, but the speaker switch is not. Tick 'speaker' and I have sound.
However.... Restart the machine, and I have to select the mixer and tick the speaker switch, or I have no sound. Volume changes are also not preserved between boots.
While the HDA support has been poor with both Zenwalk and Vector, I've not had this problem with either of them.
Any ideas for a fix?
