Re: [Sound] RH8.0 No sound

[Roger Harrington <linuxmail@xxxxxxxxxxxxxxxxxxx>]

Hi Ken 

I wonder if the program you were thinking of is called pnpdump? From
what I can see, it creates the /etc/isapnp.conf file. However, this
utility no longer appears to be in Redhat 8.0. 

Neither do I have an /etc/isapnp.conf file, so wonder if this could be
the source of my problems?

Also, a whole lot of other directories have "no such device" messages
and the directory, /dev/synth mentioned in dmesg does not exist.

Almost wonder if I should extract the soundcard, let kudzu delete the
information, re-insert card and see if kudzu can get it's act together.
