I’m running Roon Server on Ubuntu 16.04 LTS on Hyper-V. It has worked brilliantly until the last upgrade to build 324. I had disturbing pops when streaming Tidal that could best be described as static, like something shorting out. A lot of tracks were un-listenable. At first I thought I had blown speakers when my miniDSP had somehow had volume set to max while I scrambled to hit the power button. Fortunately that wasn’t the problem. I discovered I didn’t have these artifacts when streaming FLAC stored locally.
Since it’s running on a VM I was able to roll back to build 323 from a backup. The static problem went away. Based on posts of other people having what seemed to be related problems with Linux, ffmpeg seemed the likely culprit. I am no linux guru by any stretch. I knew just enough to follow Roon’s installation instructions which were “sudo apt-get install ffmpeg”. After some difficulty I was able to upgrade ffmpeg to version 3.4.2-1 and the problem went away on build 324 at least for my one test song, Don’t Wanna Fight by Alabama Shakes.
I just wanted to post my experience so it may help others and save a few gray hairs. It’s unfortunate that the new build has problems with ffmpeg version 2.8.14 because I think that’s the default for Ubuntu 16.04 so a lot of people may run into it.
