7: No Dolby/DTS audio and I still get noise through the
USB input?
• Please switch the USB port to USB 3.0 or back USB port and
try again, as some USB ports have unstable data transmission;
• Please try again with another device;
• Please replace the PC-USB cable and retest, contact me for
compensation if the original cable is faulty;
• Please change the power supply adapter and retest, why?
Because of the ageing of the power supply there may be an
abnormal power supply resulting in white noise. We recom
-mend that you connect the Micro-USB cable to a 5V adapter or
to PC's USB 3.0 port for power. Higher voltages may cause
instability.
