This is a rather odd issue that I can't seem to determine an exact cause for. I have working pcm5.1 coming from the Wii U and it sounds great in Monster Hunter, but onto the issue...
Any time I shut the console off and turn it back on after an hour or so, the sound will be stuck in stereo and will refuse to output in surround even when changing sound output settings back and forth.
I have found the only way to fix this problem is to switch video outputs from HDMI to non-HDMI and change it back again afterward, I guess to "refresh" it. After this I can finally set sound output back to surround to get 5.1 again (until the console is powered off for an extended period of time once more).
Oddly if I turn the console off and back on shortly after, this issue does not exist. It only seems to happen after the console has been off for a while. Anybody know what might be causing this and how to avoid this unnecessary hassle? I have multiple devices hooked up to an HDMI switch, however they functional correctly without having to jump through these extra hurdles.
Here is my setup:
