I have a problem with my HUD-DX1 after 3 month of exploitation. The sound quality and volume decreased dramatically (very low). I'l try started DX1 on two different PCs (and laptop) and two kinds of headphones (audiotechnica M50x and Sennheiser HD599), started with a power supply and without a power supply. Nothing helps. The LED indicator is working properly, the sound is heard, but quality is very low. Please help.
