I'm currently using Ubuntu MATE 16.04(as the title implies) on a desktop PC with external microphone. Whenever I try to talk with somebody via Skype, the participant/s in the conversation hear very annoying static and buzzing sound. If I decrease the volume, the static decreases respectively but then nobody can hear my voice. The same applies when I try to make a sound record or a screencast. I've also tried it under Win 10 and it was a bit better but only a bit.
I have ASRock Z170 Extreme 4 motherboard and I use the internal sound card.
Here is some settings info:
alsamixer's capture levels:
<Front Mic Boost> 0<>0 Line Boost 0<>0 Capture 100<>100 Capture 1 0<>0 Input Source Rear Mic Input Source 1 Front Mic Rear Mic Boost 22<>22
PulseAudio Volume Control
Input Devices tab -> Built-in Audio Analog Stereo -> Port: Rear Microphone(plugged in) (at 46%) Configuration tab -> Built-in Audio Profile: Analog Stereo Duplex
I've searched for another thread with similar problem and eventually a solution but I couldn't find anything useful.
Any help would be greatly appreciated!
