JACK configuration
Hi all,
I am attempting to record audio on my laptop. To this end, i've installed Ardour/JACK. I have *finally* managed to get ALSA to work. However, I now have a problem - the sound that is wired into the Mic In jack on the front of the laptop will play back (so basically my laptop is functioning as a speaker), but I can't seem to figure out how to get JACK to connect. Can anyone help me configure JACK so that the input will go to Ardour? The connection graph shows that system:capture1 and system:capture2 are wired to go to Ardour:Audio In 1 and Ardour:Audio In 2, respectively (so it seems like this should work). However, when the Ardour is prepped for record, the volume bars that indicate input volume are relatively static, while I can hear sound being played back. After recording, the track is silent.
Portions of the output of amixer that look relevant:
