Good evening,
New poster here. I hope I don't step on anybody's toes with the following question.
This blogger/podcaster's audio has problems for me: https://rumble.com/v20i1ok-system-updat ... ep.-2.html
There is a very much discernible high pitch background noise, a shrill, chirping noise.
I am not an audiophile, nor an audio technician (though I myself do run Linux, since 1991), but I would like to be able to ask the readers of this website, LinuxMusicians, if anyone knows what is going on here, what the problem most probably technically is, and how it can be alleviated or mitigated.
Thank you for your attention, and much obliged for any tips and/or hints.
