Astor A50: No sound when connected to PC

[Big Red Rooster]

Long story short, I'm getting no sound from my Astro A50 Wireless headset, save the humming from when I turn the volume dial on the headset to its highest setting. I think I got everything plugged in. The USB cable, the charging cable, and I'm using a 3.5mm by 3.5mm cable plugged into the headphone jack in place of the optical cable. Its been working fine up until last night. Please help.

False alarm. Turns out my headset was set for the 100% voice setting rather than the game setting.
