I found out that audio routing via Xperia xz3 usb port clipping/cuts often(randomly between 10-15 seconds interval) like cd player in car. this happened in sailfish 3.3 and 3.4. I been reverted back to android and tested out music plays without any problem. And then back to sailfish and sound keeps cutting. I tested with bluetooth headphones and that works fine. So what could cause that?

I opened terminal and watched top, cpu utilization wasn't quite high at least. Also tried different audio files (flac, mp3, ogg) and different headphones (low and high ohm). This is very unacceptable. Anyone else?
