Yes, this bug is still present on my Lenovo W530 under Xubuntu 18.04.5!
>From time to time, I can't record with audacity using the headphone
attached to the jack. Absolutely no sound appears to be recorded. If I
unplug the headset and try to use the builtin microphone, also no
recording. The computer recognizes, if i plug or unplug the headphone,
as indicated by a popup from pavucontrol.
Today I had no recording with the headset's microphone using Audacity. I
stopped the computer and booted into windows without changing anything
else. A speech recording and replay was possible there.
Then I rebooted into Xubuntu without changing anything else. Then a
recording and replay became possible. I already experienced that some
months ago, that booting into Windows10 let me use the microphone again
after I rebooted into Linux after a test recording under Windows, which
of course had worked flawlessly.
Of course, the microphone mute button was not pressed and its LED was
off (in all tested situations). Of course the microphone was not muted
in alsamixer and the volumes of Capture were set to 100% for both
channels (the microphone of the headset is a mono one, however).
To find out, what's wrong, you probably need this information:
