Since this is my first post, let me start by saying thank you to all the devs and community for a great product.
I am having a weird problem that I need help figuring out. When I stream from LMS to squeezelite the music sometimes stops playing for 20-30 seconds and then resumes playing again.
After a bit of troubleshooting I figured out that this happens because of the buffer underrun condition, but I don't know what is causing it.
On the server side I am running LMS v8.1.1 on virtualized Ubuntu 20.04.2 LTS. On the client side I started with Squeezelite-X on Windows 10, but then switched to plain squeezelite to help with troubleshooting.

LMS log to follow.
