What's the problem? Describe what went wrong.

When testing surround sound, only the front speakers work in HLE, with both the Dolphin decoder and my receiver's own decoder.

When using either HLE or LLE and the Dolphin decoder, the test sounds crackle a lot. Attached is a recording.

What steps will reproduce the problem?

1. Launch Super Mario Sunshine and play the test sounds, observe the effect and clarity of the sound.

Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.

Yes. This was tested with version 5.0-6241.

Is the issue present in the latest stable version?

Untested, really. I'd assume it is broken there too.

What are your PC specifications? (CPU, GPU, Operating System, more)

CPU: Intel Core i5 6400
RAM: 16 GB DDR4
GPU: AMD Radeon R9 280X
OS: Fedora 27
Using an Onkyo TX-NR609 receiver in 7.(0/1) surround mode and "Direct" setting.

Is there anything else that can help developers narrow down the issue? (e.g. logs, screenshots,
configuration files, savefiles, savestates)
