[MPlayer-users] more 4speaker questions

[gabor]

hi,

so i'm playing with my sb-live + 4speakersm, oss, alsa9 etc.

1.
when i'm playing an ac3(5.1) movie, ac3 5.1 means that it contains 6
(5?) mono audio channels. correct?

and when specifying -channels_4 those 6 channels get correctly downmixed
to 4, or just 2 channels get ignored?

2.
i'm trying to use the sp/dif on my sb-live ( -afm hwac3 ) ( with no
success for now :-) ....
so let's assume it would work...
now that means that i send the ac3 data directly to the card. correct?
but now how does the card know if he should create 6channels or
4channels? ( maybe this is not mplayer's problem, but maybe someone can
answer this )

3.did anyone got sp/dif work on a sb-live? i've read the archives,
DOCS/tech/*ac3* but it didn't work..... mplayer simply crashed and i had
to kill-9 it ( kill didn't help )... maybe the new audio filter system
has problems with it?

bye,
gabor
