Bug#876005: Script to remap microphone to mono for Skype

[Damien]

Package: pulseaudio
Version: 1:8.0-0ubuntu3.3

Hello

On my laptop Lenovo G70-80 with Conexant 20751/2 audio chipset, the microphone input doesn't work with Skype. It seems that Pulseaudio confuses stereo and mono with that chipset.
Here is a solution to remap the microphone to mono and to solve that trouble: it works for me on  my system.

At first, you have to get the source input name with:
$ pacmd list-sources

You pick up among other lines:
alsa_input.pci-0000_00_1b.0.analog-stereo

Then you add the following lines to the file /etc/pulse/default.pa :

### Remap microphone to mono
load-module module-remap-source master=alsa_input.pci-0000_00_1b.0.analog-stereo master_channel_map=front-left channel_map=mono
set-default-source record_mono

Restart the daemon:
pulseaudio -k
pulseaudio --start

Can you create a script who processes that automatically during the installation of the pulseaudio package?

Thank you in advance.

I am using Ubuntu 16.04 LTS, kernel 4.4.0-93-generic libc 2.23-0ubuntu9
