Hi,
I need some help please.
I have an application that does VoIP and use OSS emulated interface.
I want to :
- send through VoIP application a mixed sound from mic and an another
application (aplay should be ok for testing).
mic ----------------->
mix ---- oss emulation -----> voip application
application 1 ------->
(aplay)
- use sound received from VoIP with HP output and an another application
(arecord should be ok for testing).
---------> application 2
(arecord)
voip application ----- oss emulation ----> copy
---------> HP output
I tried a lot of asoundrc but they doesn't work. Every try I did, Dsnoop
cannot mix sound for application 1 and copy is already in use.
Could someone help me ?
# wm8731 is the name of my hardware codec
pcm_slave.wm8731 {
type hw
card 0
device 0
}
pcm.from_voip {
ipc_key 1025
type dmix
slave.pcm wm8731
}
#one called "to_voip" for capturing
pcm.to_voip {
ipc_key 1027
type dsnoop
slave.pcm wm8731
}
#and this is the real magic
pcm.temp_voip {
type asym
playback.pcm "from_voip"
capture.pcm "to_voip"
}
#a quick plug plugin for above device to do the converting magic
pcm.voip {
type plug
slave.pcm "temp_voip"
}
#a ctl device to keep xmms happy
ctl.voip {
type hw
card 0
}
#for aoss:
pcm.dsp0 {
type plug
slave.pcm "voip"
}
ctl.mixer0 {
type hw
card 0
}
pcm.from_voip_copy {
type plug
slave from_voip
route_policy copy
}
Thank you.
Fabien
