Regrettably, that does not work for me. Let me explain.<br>
<br>
I have ALSA and pavucontrol installed - they're the default, if I'm<br>
not mistaken.<br>
<br>
When I start Audacity, I click the microphone icon in the top bar and<br>
select "Start Monitoring." This shows me what audacity will pick up<br>
when I click record.<br>
<br>
If my microphone is set to "default" or "pulse", I get no response at<br>
all. The only response I get is on "sysdefault" and that works fine.<br>
<br>
Except - after that when I click record and open the sound control<br>
mixer (pavucontrol) from the panel, in the Recording tab it says no<br>
applications running that are recording, even though audacity is.<br>
<br>
It also shows only Analog Duplex Mono or Stereo in the Configuration<br>
tab. There is no other device pavucontrol sees for configuring the<br>
input or output devices.<br>
<br>
It's probably something screwy in the way LG presents the devices. As<br>
I said before, my desktop never has this problem whether I'm using the<br>
built in mic/spkr jacks or my USB Logitech headset. It sees all the<br>
devices from which to choose. The LG does not.<br></blockquote></div></div><div dir="auto"><br></div><div dir="auto"><span style="font-family:sans-serif">I've fussed with this on an old Panasonic Let's note laptop, and I don't remember everything, but I think I tried adding the jackd patchpanel and was sort of able to patch an output to an input, but it was really unstable.
