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
