hello all
maybe trivial question...
I want open sound device from /etc/asound.conf with API
snd_pcm_open() but unsuccessfull. As name i'm used:
"plughw:0,0"
"plughw:0,1"
"plughw:0,2"
"plughw:1,0"
"plughw:1,1"
"plughw:1,2"
...
i'm try alternative name with "hw:X,Y"
"hw:0,0"
"hw:0,1"
...
but in this method i'm open only HW device.
I'm get follow error:
ALSA lib pcm_hw.c:1429:(_snd_pcm_hw_open) Invalid value for card
how can i open my "virtual" device in asound.conf
here is asound.conf:
pcm.!default {
type plug
slave.pcm "output"
}
pcm.output {
type dmix
ipc_key 1024
slave {
pcm "hw:0,0"
channels 2
rate 44100
format S16_LE
}
}
pcm.dsp0 {
type plug
slave.pcm "output"
}
...exists some universal method how can i open all HW device and "virtual"
devices?
thanks
