title: Web Audio API - USB Hub
body: <p>I'm using <a href="https://webaudio.github.io/web-audio-api/" rel="nofollow noreferrer">Web Audio API</a> to create sounds and playing it to output devices.</p>
  
  <p>This <a href="https://fiddle.jshell.net/itamarsh/yr6pc20h/4/" rel="nofollow noreferrer">fiddle</a>, let you connect to two output devices, and play a tone on each one.</p>
  
  <p>This is working fine with both default output and USB outputs.</p>
  
  <p>The problem starts when using two USB outputs connected to a PC with USB Hub (no external power).</p>
  
  <p>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</p>
  
  <p>I am looking for a way to understand why its happening.
  Any help would be appreciated.</p>
  
  <p>(Also tried <a href="https://fiddle.jshell.net/itamarsh/yr6pc20h/2/" rel="nofollow noreferrer">this</a> approach, it was worse)</p>
