And in this instance, while the kernel is 2.6.18-rc6, the install itself is FC2, with lots of tarball derived mods, usually for stuff that didn't work in FC2 even after weeks of updates way back in the mists of time now. >In the case of SUSE system, the minimal setting for the multiple cards >are like below stored in /etc/modprobe.d/sound: > > alias snd-card-0 snd-emu10k1 > alias snd-card-1 snd-intel8x0 > options snd-emu10k1 index=0 > options snd-intel8x0 index=1 > >The snd-card-* aliases are even not necessary for booting/shutdown >because the other settings in /etc/sysconfig/hardware/* are used for >loading at the boot time.

And adding that seems to have stopped that nonsense. Now I have another log filler, but I don't believe its related to this. >I don't know how you got this configuration file, but it's with tons >of wastes. Please start from the minimal setting. Better yet, FC6 will replace it, from scratch, when its out. In the meantime, it works for what I want to do other than running kino for video editing. That died with the new ieee1394 kernel content at about 2.6.9ish. Presumably FC6 will have that working again. >alias snd-card-0 snd-emu10k1 >alias snd-card-1 snd-intel8x0 >options snd-emu10k1 index=0 >options snd-intel8x0 index=1 The 'index' setting is something new.
