Review on 🎧 Enhance Your Audio Experience with the Creative Sound Blaster X7 High-Resolution USB DAC 600 ohm Headphone Amplifier by Terri Owen

Got this to try to connect studio quality headphones with 5.1 Dolby Digital but it doesn't really work for PC. Dolby Digital does not work with PC on X7 over optical audio (indicated by non-illuminated "Dolby Digital" LED). For some reason it works over an optical cable when connected to a console (Xbox). I'm also trying to run a DT 1990 Pro at 250 ohms. This should be supported, but there are crackles/pops every 20 seconds or so, suggesting it can't control them properly.
