options snd-dummy index=1,2 enable=1,1 was more the issue, but:

please note that these aliases have been not necessary for some time now
as the modules export them themselves:
# modinfo snd-{pcm,mixer,seq}-oss | grep alias
alias: sound-service-?-12
alias: sound-service-?-3
alias: sound-service-?-0
alias: sound-service-?-8
alias: sound-service-?-1
> ## alias
> alias /dev/mixer snd-mixer-oss
> alias /dev/dsp snd-pcm-oss
> alias /dev/midi snd-seq-oss
and these should be automatic through the "soundcore" module handling
char-major-14 and it requesting sound-slot-? and sound-service-?-?.
So, you can loose everything but the snd-card-?/sound-slot-? aliases.

Or not. I once wasted time tracking down a non-bug due to forgetting I
had limited the number of cards like this. The default is 8...
