abstract:

the second problem, /dev/dsp is independent of that. do you have your sound card (and the wave out device) configured?
/dev/dsp is the channel for outputting wav files. (try "cat /data/windows/media/chimes.wav >/dev/dsp")
could also be a permissions problem, but probably the sound card is not setup at all. is it?


to your first problem:
for audio cdroms, you need access to the raw device (/dev/cdrom whis is a link to /dev/hdb here -> you have your cdrom on the primary slave port.)
/dev/cdrom is owned by root.root
are you logged in as root or is your user member of the "root" group? if not, you cannot acces it
can you mount a data cd-rom? (you still might be able to since mount is most times SUID root)
the second problem, /dev/dsp is independent of that. do you have your sound card (and the wave out device) configured?

change group membership:
- edit /etc/group
- add your username to the line with "root:0:..."; separate multiple entries with commas.
also check "ls -l /dev/hdb" for i am not sure if links inherit their target´s permissions and/or ownership. for SuSE i think the group was "disk"...
setup sound card: this could fill a book of its own
which distro are you using? SuSE and Redhat have automated tools for this. i only know SuSE and the low-level way. SuSE: start "alsaconfig" (alsasetup?). you need to have the package "alsa" installed.
there is another sound driver package, "oss", which requires license fees so i doubt SuSE or Redhat still come with it.
some hardware manufacturers have install instructions also for linux on their homepage
and last, but not least - the kernel drivers. linux itself also has kernel modules for the most common sound cards.
which brand and type is it?

Slackware... uh, one for the hard ones
one solution is to put the "modprobe" in a startup script. not that odd. remember c:\config.sys?
another one is to edit /etc/conf.modules (/etc/modules.conf depends on distro) and setup automatic loading of modules when necessary...
alias snd-device-0 maestro3
(needs modification to work... see /var/log/messages for the correct "snd-device-0" after accessing /dev/dsp)
