I write a asound.conf file in the /etc/ , the detail is as follows.
pcm.hardware{
type hw:0
card 0
device 0
}
pcm_slave.test {
pcm "hardware"
format S16_LE
rate 44100
channels 2
period_time 20000
buffer_time 80000
}
pcm.mix1{
type dmix
ipc_key 1235675
ipc_key_add_uid true
slave "test"
}
pcm.mix2{
type dmix
ipc_key 1235675
ipc_key_add_uid true
slave {
pcm "hw:0"
format S16_LE
rate 44100
channels 2
period_time 20000
buffer_time 80000
}
}
pcm.!default {
type plug
slave.pcm mix2
#slave.pcm mix1
}
when I use the slave.pcm mix2, the aplay works well. but if I select the slave.pcm mix1, the aplay gets the info:
ALSA lib pcm_direct.c:1462:(_snd_pcm_direct_get_slave_ipc_offset) Invalid type 'dmix' for slave PCM
I compare the definition of mix1 with the definition of mix2, I feel they have the identical meaning. so why does the mix2 get the error?
thank you!
