I needed to post a question here since after numerous Google searches and attempts I couldn't solve this problem. So here's my problem:
My system consists from a PC computer with Ubuntu 18.04.3 LTS, GeForce GTX 1080 Ti and three displays connected. I'm using JABRA Evolve 65 headphones (connected via USB cable to PC) for my sound output and after upgrading Ubuntu 16.04 to 18.04 (clean install) I haven't been able to fix my sound issues (in 16.04 everything worked fine).
When I listen to, say a Youtube video, I can hear the sound but it is breaking up a lot, like it would have a lot of interference or something. Occasionally the sound is ok like 2-3 seconds and then again it starts breaking up again a lot. It sounds like someone would be pausing the sound and then very quickly turning it back on. That is, if you look at a Youtube video and press and hold space, that's almost identical to what my sound problem is like.
I have tried changing the default sample rate from 44.1kHz to 48kHz in the pulse daemon.conf, but this did not help me.
Any ideas what I could do? Thank you.
