rhsound-1.8 does not require aumix-1.18.2-2 but rhsound's /etc/rc.d/init.d/sound uses aumix -f which (afaik) only exists in 1.18.2-2 -- caused some confusion tracking down "aumix: unknown option -f" messages from /etc/rc.d/init.d/halt and /etc/rc.d/rc.sysinit (hey, i said it's low priority)
This issue has been forwarded to a developer for further action.
Hm, it did seem to show up between 1.13 and 1.18.2. Oops. This will probably be fixed in the future when rhsound disappears. ;)
fixed in aumix-1.22.1-2, which now includes the sound init script...
