sound on the 770z

[Rob Mayoff]

| So I have had some success with the kernel sound drivers -- it says
| 'interrupt test failed (IRQ5)' when I install it, but seems to work
| anyway.

same here (using OSS)

| However, volume is very low.  On one of the thinkpad/linux web
| pages I found a reference to a "master volume control" which needs to be
| moved up, but there's no reference to this in the thinkpad manual or
| configuration utility.

I saw that mention too. I think it's referring to the physical volume
control on the side of the case. I set mine to about 2.5, and set the
software master volume to about 90%. This gives me plenty of volume
(through my headphones) without much hiss.
