I'm still stuck with this. I went over the Sound-HOWTO and the
isapnp docs again and then tried to reconfigure the sound card and recompile
the kernel sound support. I thought I had this licked, but I still get the
I/O errors on /dev/audio and /dev/dsp.
If anybody understands sound and hardware registers, etc, better
than I do, I would sure love a hand with this. I have included the pnpdump
file which I edited to use as isapnp.conf, and the relevant bits from the
kernel .config file in case anyone can spot what i am doing wrong. I've
tried a number of different combinations and nothing seems to work, which is
frustrating since I had this working first go round on a bo (1.3) box.
Here are the files, Thanks in advance.
