ahhh thanks kevin... yes that would make perfect sense, i noticed that
mandrake was using 0.9.rc2 and naively assumed that i'd manage to
upgrade it if i installed 0.9.rc5 from source (im not using rc6 yet
because of the record problems in usb-audio - not sure if they were
there in rc5 as well ).

ok.... slight problem in that i've already run ./snddevices....
should i uninstall alsa 0.9.rc2? or just manually remove the modules it
has installed?
i'll install the extra libs, and i've got an .asoundrc for the quattro

my alsa portion of modules.conf reads like this at the moment: would you
be able to correct it for me? im familiar with oss but quite new to
alsa.... so im not used to these structures...

# OSS/Free portion
alias char-major-14 soundcore
alias sound-slot-0 snd-card-0
#alias sound-slot-1 snd-card-1
# card 1
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss

alias /dev/sound sound-slot-0
alias /dev/audio /dev/sound
alias /dev/mixer /dev/sound
alias /dev/dsp /dev/sound
alias /dev/dspW /dev/sound
alias /dev/midi /dev/sound

| alias sound-slot-0 snd-rme9652
