Re: Internal microphone not detecting any input

hmm! Sorry I am such a drongo . . .  I gave the wrong wpctl command - - meant to be: - -

wpctl set-mute @DEFAULT_AUDIO_SOURCE@ toggle

You can also use    get   to see what the mic input gain is set to.

wpctl get-volume @DEFAULT_AUDIO_SOURCE@

it may be set really low ??

wpctl set-volume @DEFAULT_AUDIO_SOURCE@ 1.0

- - not sure what the range is? -   maybe 0.0  to 1.5 ?

Re: Internal microphone not detecting any input

Instead of random guesswork, post the outputs of the following in  [code][/code] tags

arecord -lL
amixer -c0 #Replace the 0 with whatever index of your actual mic card arecord gives you
pactl list cards
pactl list sources

afaik, if you're unlucky this might be a driver bug in how the "wiring" is set up on a driver level, but let's look at those outputs first.
