Could you please download the free files in the links in the first post and let me know.
Try the first piece "Mozart: Violin concerto in D", column Surround 5.1 FLAC 24BIT/96kHz, it's the file I play for testing

Works flawlessly. Where do you keep your media and how (using which protocol) do you access it?

I have an USB HDD attached to a powered hub.

What file system do you use on the hard drive? Can you run `top` in a console while listening music, then press `H` (for threads view) and copy/paste top output?

[MrNice]

USB HDD file system is ext4

While listening music, "Mozart: Violin concerto in D", column Surround 5.1 FLAC 24BIT/96kHz,
