Hello, I recently bought a new motherboard (GA 990FXA-UD3) and have a problem with the sound card (Realtek ALC892). My speakers are using a rca connectors using a rca to 3.5mm cable to insert in the motherboard (might be the issue but worked fine before). So everything is fine in the realtek manager when playing the speakers 1 by 1, but when playing music the bass only works if I set the Realtek Manager to register the center/subwoofer as Front speakers. If I set them as they should be (center/subwoofer registered as center/subwoofer in Realtek) sound comes only from the Center speaker. Also, when playing videos online (youtube) sound only comes from the right speakers. The speaker fill and center/subwoofer swap options are missing from the manager. Help is appreciated!
