Can't play CD / mount CDROM

Hey Toomas,
Thanks for your detailed reply. As far as problem #1: When I re-complied to
statically include the sound it gives me no output, not even when I used
kldload to load the driver... it simply loads without any output... How do I
check mixer settings?
I am religiously following step by step instructions to the installation:
Chapter 7.2.3:
Did this screw up my output?
# sysctl hw.snd.pcm0.vchans=4
# sysctl hw.snd.maxautovchans=4
As for problem #2 which is the frustrating part and I need to get working is
- I used to be able to mount my /cdrom and view files on the CD - even if
they meant MP3s & even it meant I could not play them back... Now it simply
goes to the error: cd9660: device /dev/acd0 Input/Ouput error
It's been the start of week#3 and this is taking too long to setup one
operating system !! (that's where windoze wins, simply pop in the CD and
forget-about-da-rest). I guess I lost my original kernel so that's why I'm
in an endless loop... :o(
Thanks for your response I'll send y'all the output from the 'grep acd0
/var/run/dmesg.boot' I'm away from my PC right now.
