I wanted to create some simple tutorial videos using a screen recording software (with gtk-recordMyDesktop to be precise), but the audio quality was terrible. There was a constant white noise in the background. I could reduce the noise with Audacity but 1) I couldn’t eliminate the noise, 2) it distorted my voice, and 3) the audio became weaker.
I had a cheap headphone / microphone that was connected with a jack plug. I think there was also some inference that caused the noise. So I bought a USB headset (Logitech H390) and the damn noise is gone! It works very well for me.
I tried it under Manjaro and here is how to make it work. Plug it and start Audacity. Next to the microphone icon there is a dropdown list. Select your headset and try to record some audio.
Try “pavucontrol” too. Under the Recording tab I had to select “Headset H390 Analog Mono”. Talk in the microphone and the sound feedback line should be moving.
How to record audio with gtk-recordMyDesktop? Start “pavucontrol” and “gtk-recordMyDesktop” too. In gtk-recordMyDesktop, go to Advanced -> Sound tab. Next to the device name I had “DEFAULT”. Change it to “pulse” (without quotes). Start recording with gtk-recordMyDesktop. Now switch to pavucontrol and go the Recording tab. At the bottom select “Show: Applications”. Now recordmydesktop should appear. Next to it there is a dropdown menu where select “Headset H390 Analog Mono”. It should do the trick.
On my external HDD I created a new ext4 partition. When I mounted it, it was in read-only mode. What’s going on?
sudo chown -R username:username /place-to-mount
