What's the problem? Describe what went wrong in few words.

When using the OpenAL backend, audio is put out over left, right and center channels. Center channel audio is approx. 300% louder than left and right.

What did you expect to happen instead?
Balanced audio or 2 channel output as with XAudio2.

What steps will reproduce the problem?

  1. Use OpenAL backend without DP2 decoding

Dolphin 3.5 and 3.5-367 are old versions of Dolphin that have
known issues and bugs, so don't report issues about them and test the
latest Dolphin version first.
Which versions of Dolphin did you test on?

4.0-5408

Does using an older version of Dolphin solve your issue? If yes, which
versions of Dolphin used to work?

Unknown

What are your PC specifications? (including, but not limited to: Operating
System, CPU and GPU)

Windows 8.1 x64, i5-4690k, AMD R9-270X, Creative Audigy 4, 5.1 audio

Is there any other relevant information? (e.g. logs, screenshots,
configuration files)

Audio is properly balanced across all channels when using Pro Logic II decoding with a game that supports DPL2 (e.g., Rogue Leader).
Audio is even more messed when using DPL2 decoding with a game that does not make use of DPL2 (e.g., Xenoblade), with audio cutting in and out of all channels in addition to a very loud center channel.
