When using the HDMI output via a Dell E7240, every so often the sound drops and the picture hangs for a second and the sound goes out of sink, so I pause the play back and release the pause of which this brings the sound back in sink for a minute or two. I have checked the Power management of the USB’s of which are not checked so there seems no reason for the laptop to put the device to sleep for a second.
