Rich,
I looked at filedata.lst, it had only:
opt
home ;
I then modified it:
opt/alsa
etc/modprobe.conf
home ;
if this is what you meant, it had no effect, and in fact, on reboot, the filedata.lst had been restored to:
opt
home , it's default state.
I then reinstalled tiny with the smaller iso image and got exactly the same behaviour. Oddly, the front setting survives,
but the master setting goes back to zero
BTW, where is the info file for the alsa/alsagui?
