Hi everyone,
I am attempting to utilize my asound.conf to create a virtual
interface out of two delta 410 cards. There are several examples
of this online, but even after digesting them and plunging into
the ALSA doxygen docs, i am still unable to make jackd happy.
My understanding is that a route plug is inefficient but
necessary for jack to lock down the memory(unless the
MMAP_COMPLEX patch is applied). Using jack 0.99.0
jackd -v -d alsa -P ttable_play results in the error...
ALSA lib pcm_multi.c:970:(_snd_pcm_multi_open) Unknown field 10
ALSA: Cannot open PCM device alsa_pcm for playback. Falling back
to capture-only mode.
The playback portion of my asound.conf follows. Any help would
be greatly appreciated. I actually thought I understood the
configuration process until it failed to work. ;)
thanks in advance,

pcm.multi_playback {
type multi
slaves.a.pcm hw:1 <----------------------
"hw:0"?
slaves.a.pcm channels 10
slaves.b.pcm hw:2 <----------------------
"hw:1"?
slaves.b.pcm channels 10
#note that ice1217 chip actually has 10 outs(8 analogue on 410)
I don't know much about .asoundrc configuration, but should the
"hw" index start at 0?
Yeppers, but AlSA defines card 0 to be my main board's built in audio.
card 0 -> CK8S
card 1 -> M410
card 2 -> M410
thanks,
