Hi,
I'm running alsa-utils version 1.0.8 with kernel 2.6.16 on my ipaq, which
actually has a pretty decent sound card, the philips uda1380.
Anyway, i've gotten full-duplex sound to work, arecord | aplay,
but i'm trying to get the dmix plugin going.
aplay works fine for either cd or dat quality,
but if I try to do aplay -D plug:dmix 1.wav i get:
aplay -Dplug:dmix 1.wav
ALSA lib pcm_direct.c:637:(snd_pcm_direct_initialize_slave) slave plugin does
not support mmap interleaved or mmap noninterleaved access
ALSA lib pcm_dmix.c:880:(snd_pcm_dmix_open) unable to initialize slave
aplay: main:508: audio open error: Invalid argument
i've tried a variety of /etc/asound.conf's, the latest being:
pcm.!default {
type plug
slave.pcm "dmixer"
}
pcm.dmixer {
type dmix
ipc_key 1024
slave {
pcm "hw:0,0"
period_time 0
period_size 1024
buffer_size 4096
rate 44100
}
bindings {
0 0
1 1
}
}
ctl.dmixer {
type hw
card 0
}
from the alsa docs page for .asoundrc, but whatever i try (even without an
/etc/asound.conf ) i get the same error.
I do have the drivers loaded and sound playback works fine, as does record,
just can't get dmix going.
cheers,
Matt
