Microphone distortion on Thinkpad X220

+

Trying to fix a bad microphone

+

The X220 has a notoriously bad internal microphone. It can be somewhat improved by making the input mono with module-remap-source

+

/etc/modules-load.d/microphone.conf

+
+# make micro mono
+module-remap-source master=alsa_input.pci-0000_00_1b.0.analog-stereo channels=1 master_channel_map=front-left channel_map=mono
+
+

Replace master= with your device, and master_channel_map= with the device's channel

+

It's a bit better, although an external usb microphone is the real solution.
