Hi,
Firt of all, I apologize for my bad english 
My problem is I can’t have the stereo working : I hear sound on both channels but when I move the pan control to the left side, I just have more volume on the both sides. When I move it to the right side I hear less sound.
On the master outputs, I have no sound when I desactivate the left playback. Nothing changes with the left channel activated and the right one desactivated.
(It happens enven with a stereo song imported to ardour).
Jack is running and configured, I’m on Archlinux and I have a Focusrite 18i20 (2nd gen), plugged by USB.
I’m listenning with headphones plugged on my soundcard.
Some files which could help :
$ more .asoundrc
pcm.!default {
type plug
slave { pcm “pulse” }
}
pcm.pulse {
type pulse
}
ctl.mixer0 {
type hw
card 0
}
and
$ more /etc/asound.conf
pcm.pulse {
type pulse
}
ctl.pulse {
type pulse
}
pcm.!default {
type pulse
}
ctl.!default {
type pulse
}
pcm.!default {
type plug
slave { pcm “jack” }
}
ctl.mixer0 {
type hw
card 1
}
pcm type jack
pcm.jack {
type jack
playback_ports {
0 system:playback_1
1 system:playback_2
}
capture_ports {
0 system:capture_1
1 system:capture_2
}
}
On this site, I can hear the left and center files (on both side of my headphones) but not the right one. So it’s not a ardour related problem. I don’t know if it’s the right place to post. Sorry if it’s not…
