Well, as I reported it didn't. But I made progress in the meanwhile:
Using "copy" didn't work either but adding "slave.channels 6" to your
config results in output also from the two rear speakers. YEAH! ;)
That means I can use this smaller config instead of my old and bigger
"ttable one" for stereo sources (device duplicate in xmms)
Problem fixed: YES [X]
Nevertheless, playing real 5.1 sound still doesn't work.
I was able to get it by using
"gmplayer dvd://1 -v -aid 128 -ao oss -channels 6"
but I would like to get it to work also with alsa.
What I tried next was using the following config and
"gmplayer dvd://1 -v -aid 128 -ao alsa9:default -channels 6"
---------------------------
pcm.!default {
type plug
slave ice1724_S32_LE;
}
pcm_slave.ice1724_S32_LE {
pcm surround51;
format S32_LE;
}
---------------------------
Also a little progress: Sound out of all 6 speakers without further
configuration. But unfortunately the channels got mixed up:
Gandalf is talking out of the left rear channel, now :(
Without "-channels 6" no more sound out of both rear speakers...
How can I check the assignment of channels and speakers and
how can I modify them?
That's the output using the "-channels 6" option:
