i want to merge my two devices (analog and digital) to be able to use
them together in jack/qjackctl.
my card configuration is:
hw:1,0 -> 2 in, 8 out
hw:1,1 -> 8 in, 8 out
which is an asymmetrical "look".
so i created a /etc/asound.conf file (see below).
but when i start jack, it says:
ALSA: mmap-based access is not possible for the capture stream of this
audio interface
ALSA: cannot configure capture channel
this is because i used a null pcm with the asym plugin (i think).
anyone knows how to workaround this?
here is my asound.conf:
pcm.!default {
type plug
slave sl44100
}
ctl.!default {
type hw
card 1
}
pcm_slave.sl44100 {
pcm "hw:1,0"
channels 2
rate 44100
}
pcm.Gina_Capture {
type asym
playback {
pcm {
type null
}
}
capture {
pcm {
type hw
card 1
device 0
}
}
}
pcm.Gina_Playback {
type asym
playback {
pcm {
type hw
card 1
device 0
}
}
capture {
pcm {
type null
}
}
}
pcm.Fostex_ADAT {
