I have a Genius150 watt 5.1 speaker system Genius I dont have the realtek driver installed since the sound quality was not satisfying with it so I stayed to the default high definition audio device with stereo configuration. I have an integrated sound card. This is my motherboard model GIGABYTE - Motherboard - Socket 1155 - GA-P61-S3 (rev. 2.0) I want to know what sample rate and bit depth to choose for best quality playback at advanced speaker properties? The default ones are 16 bit , 44100 cd quality like you can see in the below image I dont understand what is that shared mode either. If I install again the realtek driver what should I choose then ?
