Microphone not working: Ubuntu 14.04.3

Hi,

Sounds systems used in Linux distros are quite flexible - so, it is possible swap the audio channels as you like.

Can you try this:

Not sure about the mic though - so my proposals will be a bit vague.

First, inspect the output of:

Code:

$ cat /proc/asound/cards

I'll assume you have alsa-utils installed: does recording with ALSA utilities - like arecord - work?
ALSA mixer is (alsamixer) also quite good in diagnosing - do you see the input in it, is it not muted, are the recording levels right?

Thanks,
Michal
