Its only the mixer app Hamish
mixer_app  6382 richard-g8jvm   17u      CHR      116,0                
7895 /dev/snd/controlC0

I've also tried recompiling gmfsk as me and not as root
-rwxr-xr-x 1 root root 1283122 Oct 31 09:06 gmfsk*
-rwxr-xr-x 1 root root 1453277 Oct 23 12:17 gpredict*
-rwxr-xr-x 1 root root  822682 Oct 20 14:46 xlog*

Added the line that Al suggested in rc.local
chmod 666 /dev/dsp /dev/audio /dev/mixer /dev/cdrom

no immediate effect, but worked after rebooting, so it looks like the 
permissions
are only read at startup on the above files, which is a bit strange as 
normally you can change file permissions
on the hoof and take immediate effect.
Must be some Mandriva security measure that been added in MDV2007.

Thanks for all the help
