[Alsa-user] M-Audio Revo sadness

Jeff Martin Sun, 06 Jul 2003 22:12:47 -0700

I can't get my revo [ice1724] card to work the way I'd want. What I want is to send 5.1 sound to my receiver. My receiver has external decoder inputs in 5.1, as well as coax and optical S/PDIF inputs. I can't get any of these to work right.

Setup:
        AMD 1700+
        Soyo Dragon Ultra (KT400) mb
        1 GB ram
        Mandrake 9.1 linux
        alsa from cvs

First, I tried using the analog outs from the revo to the receiver. I could get 2.0 sound, but anytime I tried anything that does 5.1, it would act like it was working but I would only get 2.0 sound. I tried "ac3dec -6 AC3TEST.VOB". It would output rates, and pause for about how long the vob was, but no sound. By moving the cables around, and I could individually test playing stereo out to the fronts, to the rears, and to the center, so the cables and the receiver seem good.

So I gave up on that. I then switched to the coax S/PDIF on the revo and removed the analog cables. Now I can't get stereo or 5.1. "ac3dec -C AC3TEST.VOB" yields "Using PCM device 'plug:iec958:{AES0 0x2 AES1 0x82 AES2 0x0 AES3 0x2}' AC3 Stream 48.0 KHz 448 kbps" but no sound.

My questions:
1. How do I get 5.1 from the analog cables on the revo?
2. How do I get 5.1 from the S/PDIF on the revo?
3. How do I pass 2 channel .wav files over the S/PDIF on the revo?

Thanks!

Jeff


alsa built from cvs (updated yesterday) with:
./cvscompile --with-cards=ice1724 --with-sequencer=yes

/usr/share/alsa/cards/ICE1724.conf is the same as the cvs copy

Note on /etc/asound.state -- I've twiddled this file so many times, it may be easier to regenerate it than try to fix it.
