Bug ID: 489198
Summary: Unable to use internal microphone once headphones are
connected
Classification: Plasma
Product: plasma-pa
Version: 6.1.0
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: bugs_kde_org.5.k...@spamgourmet.com
CC: isma...@gmail.com, m...@ratijas.tk
Target Milestone: ---
(I have no idea where to put this report, so feel free to move it wherever it
fits)
SUMMARY
I have a PC with a dual purpose 3.5mm jack (headphone/microphone in one port).
As soon as I connect headphones to the PC (plug it into the port) I can no
longer use my internal microphone (Audio Profile: Analog Stereo Duplex). Once I
unplug the headphones the internal microphone works again.
STEPS TO REPRODUCE
1. Have a PC with a dual purpose 3.5mm jack (in my case: Lenovo ThinkBook 16)
2. Plug in headphones
3. Try to record audio over the internal microphone
OBSERVED RESULT
The internal microphone does no longer work even I did nothing but connect the
headphones to the combined audiojack. I did not find any way to 'force' the
system to change the source for audio input (like you can do with
speakers/headphones for the output).
EXPECTED RESULT
Internal microphones works no matter if headphones are plugged in or not.

ADDITIONAL INFORMATION
1)
I have no idea if this is caused by the laptop or not (I have also no idea how
I could test this). Maybe the laptop does cut out the internal microphone once
a something is plugged in to the audio jack no matter what it is. IMO a contra
argument to that theory is the fact that when I connect the a standalone
microphone (so occupy the audio jack) the internal microphone works fine.
2)
When I connect the headphones, open the pulse audio control center and take a
look at the input devices, it says that the microphone is plugged in (looks
like this is caused by my headphones) and the internal headphones are
disconnected. Once I unplug my headphones it says the the microphone is
disconnected and it auto-switches to the internal microphone. When I plug in my
standalone microphone with 3.5mm jack it still says that the microphone is
unplugged, but the internal microphone is working.
3)
I want to test a 3.5mm microphone/headphone splitter and see how (and if) this
works. So far I don't have one at hand.
4)
My current workaround is to use a wireless headset over bluetooth. Not really a
good solution, but it works for now.
5)
I found this old bugreport: "Can't record audio from built-in microphone while
headphones are plugged into headphone jack"
