Dolphin Surround Sound over HDMI

[liam2503]

Hi,

I'm currently using in the process of buying a new A/V Receiver to connect my PC to my Home Theater Setup and I would like to know if I should purchase a receiver with Multi-Channel RCA Inputs (5.1ch) or just simply connect with HDMI to obtain Surround Sound from Dolby Pro Logic II encoded in Wii Games.

I know already that Dolphin natively decodes the Dolby Pro Logic II sound, so is this output through the 3.5mm Surround Sound Jacks on my motherboard or can I get this over HDMI?


I'm really trying not to have to use the 3.5mm jacks are connecting them via RCA to any receiver is becoming harder and harder these days as nearly none of the receivers have Multi-Channel RCA Inputs (5.1ch). If HDMI is a no-go for surround sound from Dolphin, are there any other solutions for getting surround sound?


Current Motherboard: Gigabyte B360M D3H-CF
Current Graphics Card (HDMI Output): Gigabyte NVIDIA GeForce GTX 1050 (GV-N1050OC-2GD)

Last time I checked, the only way to get DPLII output from dolphin was using LLE DSP to emulate the sound chip more faithfully. This takes a toll on performance so make sure your PC can handle it. Dolphin offers a DLPII decoding feature but I was never able to make it work with HLE. I was only able to get it working with LLE, which defeats its purpose, and the sound was not correct.

The best way I've found to test if you are getting the correct output is in the audio test screen of Super Mario Sunshine. Try that with DSP LLE so that you can see how it is supposed to sound like. The drum sounds cycle through the various speakers.
