Re: [Thinkpad] 600E/Win98SE: (still) no sound *from speakers* (partially!)

Yes, it's yet another post from the guy with the mute Thinkpad ...

I had to take a little while off, because in the meantime (I couldn't get
the dock theory sorted out) I did some cross-platform testing;
I installed the following OSs with the *correct* drivers - the results:
- Windows 98: (as you all know) perfect sound over headphones, no sound over
speakers.
- OS/2 Warp 4: exactly the same, perfect sound over headphones, no sound
over speakers.
- BeOS R5 Pro (out of the box, without additional drivers!): exactly the
same again, perfect sound over headphones, no sound over speakers (I know,
it's kinda boring).
- Windows 2000 (without additional drivers): Big Surprise, perfect (if you
don't mind a little distortion) sound over both speakers and headphones!

So, considering that the original drive with Win XP worked, too, this seems
to be something that affects *every* OS except for the Windows NT(/2000/XP)
family. I was most surprised to see BeOS show the same misbehavior, as it
AFAIK has absolutely nothing to do with DOS (which the others might have in
common in some way).
Maybe you have to configure the Thinkpad using the DOS configuration even
when you don't use something DOS-based, and only 2000/XP override that
setting?
I found a web page indicating something like that, dealing with the
installation of Linux: http://www.mainsheet.org/thinkpad600e. I didn't
install Linux, as I don't understand it.
But I *did* enable audio with the DOS utility, and it didn't change
anything.
Another thing I noticed under Win2000 is that the audio system uses up an
interrupt for ISA (5) and one for PCI (9, shared). Does that say anything?
