MIC
Inaudible or robotic voice.
Volume booster and channel adjustment
***
Nowadays using the microphone for online meetings has become essential. I had
so much trouble adjusting my mic and I almost gave up on using Linux. Several
people have the same problem and it happens in other distributions as well.
Before an online meeting I test the microphone, but in the middle of the
meeting it stops working. I noticed that the problem is in the auto volume
adjustment.
The solution I found was:
1 - (make the microphone sound audible and clear) install win7 mixer widget.
has the option to adjust the left and right channels. For me the mic sound is
good with 50% right and 15% left.
2 - Stop automatic volume adjustment -
kate /usr/share/pulseaudio/alsa-mixer/paths/analog-input-mic.conf
kate /usr/share/pulseaudio/alsa-mixer/paths/analog-input-internal-mic.conf
Under “[Element Internal Mic Boost]” set “volume” to “zero”.
Under “[Element Int Mic Boost]” set “volume” to “zero”.
Under “[Element Mic Boost]” set “volume” to “zero”.
My suggestion is that Plasma has the options to adjust the channel and stop the
automatic volume adjustment.
