I have used Audacity on Windows quite a bit and now I have Ubuntu Studio running on Lubuntu 14.04.
The headset jack on my Odroid U3+ is working but the level of the mic is too high. The track plays back
on both the headset and the monitor through HDMI. On Audacity the mic level control says “Unavailable;
use system mixer.” and you can’t move it. I have tried all the mixers, none of them work. I am using
JACK Audio Connection Kit and both speaker and mic choices are “system” as this is the only thing
that works, but the level is much too high on the mic. The “Mixers and Card Control” choices are:
PulseAudio Volume Control
but none of these will change the mic level.
