We are using Web Audio API on latest Chrome to create sounds and playing it to output devices.

This [fiddle](https://fiddle.jshell.net/itamarsh/yr6pc20h/4/), let you connect to two output devices, and play a tone on each one.

This is working fine with both default output and USB outputs.

The problem starts when using two USB outputs connected to a PC with USB Hub (no external power).

After playing a while (and using the PC for other tasks, thus creating some workload) the sound breaks in one or both of the outputs

I am looking for a way to understand why its happening.
Any help would be appreciated.
