Public bug reported:
Since upgrading to 20.04, when plugging an headphone with integrated
microphone in my Dell Vostro15 the system makes a display of changing
sounds settings (i.e. a volume bar is showed with the headphones sound
level) but no sound is coming out either from the headphones or the
system speakers.
Opening the audio mixer settings, I can see that the selected output
device is "Headphones (plugged in)" (the other displayed alternative
being "Speakers (plugged in)". The selected input device is "Microphone
(plugged in)" and there are two other alternatives: "Headset Microphone
(plugged in)" and "Internal Microphone (plugged in)".
If I change the setting for the *input* device from "Microphone" to
"Headset Microphone" sound magically starts coming out of the
headphones.
It may or may not be useful to remark that if I unplug the settings for output
device changes to "Speakers (plugged in)" while the "Headphones" alternative is
now correctly marked as unplugged and sound comes out of the speakers as
expected. The situation for the input device, however, is slightly surprising:
- If I changed the settings as described above the settings stay the same,
i.e. "Headset microphone (plugged in)"
- If I let the input device unchanged (i.e. "Microphone (plugged in)", it
switches back to "Internal Microphone (plugged in)" while the "Microphone"
device has its status reported as "unplugged".
In both cases, the input device "Headphone microphone" keeps the "plugged in"
status
