XPS 9560 USB audio issue

I recently bought the Dell XPS 9560 with Windows 10 Home preinstalled.

Unfortunately I am experiencing an issue while playing music on my USB stereo audio system:

if I pause or stop the playback (aimp3, youtube) for about 30 – 40 seconds, there is a brief cracking noise in the speakers, and then no sound is sent anymore to the USB stereo when I resume the playback, or in Windows if I set it to default stereo system.

My first idea was to set to Disable the USB selective suspend setting, but this was not the cause for the lack of sound.

For the moment the only way to overcome this issue is to disconnect/ reconnect the USB DAC.

My audio setup (Laptop – USB DAC – Amplifier – Speakers) works fine on older laptops with Windows 7, with no sound issues after pausing or stopping media, so I don't know if this issue is caused by a Windows 10 setting, or by Dell XPS 9560 drivers.

How can I have USB audio after I pause or stop media? I have the latest drivers via Dell update software.

Thanks

Andrew
