If the sound driver is compiled in the kernel and not as a module, the aumix-minimal loading is not run because it is inside the modules "if". Putting it outside the "if" is the solution... The same error had been made a few versions ago.. like in 6.0 I think....
Actually, it shouldn't be there at all. Thanks for reminding me, it will be removed in 5.84-1.
If it should be there at all, where are the mixer settings loaded then?
They should be loaded upon device registration; the cleanest way to do that is with post-install scripts for modules. Ideally, the modules should only be loaded on demand and there shouldn't even be stuff in rc.sysinit for that, but ISA braindamage sort of requires it.
Is there such a script included in RH7.1 ? If so, where? (which packages?)
By post-install scripts for modules, I simply mean in modules.conf post-install sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -L Unfortunately, I don't think this works for the static case.
I still believe that the right solution for the static case is for it to be in the rc.sysinit. Putting before any sound module can be loaded will make sure that it is just triggered in the static case.
