ac3 passthrough?

fackamato · 03-08-2004, 01:33 PM

I'd like to get AC3 passthrough working with xine and mplayer. I've got slack 9.1, kernel 2.6.3 with alsa included, sound is working fine, except no ac3 output. Mainboard is an ASUS p4p800 (intel 8x0), ich5 chipset, or AD1985 (analouge devices) if that helps

I've seen others using the -hwac3 parameter for mplayer, but I don't seem to have such a thing there

Please help

IIRC ac3 passthrough is only an option with certain creative chips.

Soundstorm is a windows application from nvidia. I have it installed but I haven't booted into XP for about 6 weeks.....as far as I can recall it dosn't give me an option to use ac3 passthrough, but that maybe because of my speakers (Creative Inspire 5100), I do have a pioneer souround/dts decoder that has an optical input (which I think is a requirement for ac3 passthrough), but thats connected to my HTPC.

huh? Soundstorm is a feature in the nforce2 northbridge iirc? It _surely_ can give you ac3 passthrough, with options in the media players/filters/decoders you use, I've done it myself when I had an nforce2 board. To get ac3 passthrough, use ac3filter, set it to output to sp/dif instead of speakers, done.

Hm
