Hi,
I want to use Asterisk with ALSA / Jack audio.
I tried the next configurations :
1 ) app_jack.so -> does not work.
2 ) chan_alsa.so without jackd started
my .asoundrc :
pcm.!default
{
type hw
card 1
}
pcm.jack1 {
type jack
playback_ports {
0 alsa_pcm:playback_1
1 alsa_pcm:playback_2
}
capture_ports {
0 alsa_pcm:capture_1
1 alsa_pcm:capture_2
}
}
pcm.jack1b {
type plug
device jack1b
server linux
slave {
pcm "jack1"
rate 8000
format FLOAT
channels 2
}
}
ctl.mixer0 {
type hw
card 1
}
in alsa.conf :
input_device=default
output_device=default
That works fine.
3 ) chan_alsa.so with jackd started
Jackd launch command :
jackd --port-max 16 --realtime --no-mlock -d alsa --playback hw:1,0
--capture hw:1,0 --rate 8000 --period 1024 --shorts --inchannels 2
--outchannels 2 --dither triangular &
my .asoundrc :
pcm.!default
{
type plug
slave {
pcm "jack1"
rate 8000
format FLOAT
channels 2
}
}
pcm.jack1 {
type jack
playback_ports {
0 alsa_pcm:playback_1
1 alsa_pcm:playback_2
}
capture_ports {
0 alsa_pcm:capture_1
1 alsa_pcm:capture_2
}
}
pcm.jack1b {
type plug
device jack1b
server linux
slave {
pcm "jack1"
rate 8000
format FLOAT
channels 2
}
}
ctl.mixer0 {
type hw
card 1
}
in alsa.conf :
input_device=default
output_device=default
It doesn't work. Asterisk outputs are :
[Oct 3 10:34:50] ERROR[1364]: chan_alsa.c:175 alsa_card_init: snd_pcm_open
failed: No such file or directory
[Oct 3 10:34:50] ERROR[1364]: chan_alsa.c:175 alsa_card_init: snd_pcm_open
failed: No such file or directory
[Oct 3 10:34:50] ERROR[1364]: chan_alsa.c:272 soundcard_init: Problem
opening ALSA I/O devices
But aplay my_test_file.wav works fine and arecord too...
Does anyone have an idea ?
Thanks,
Fabien
