One of the two stereo channels is muted in MegaCD games on Wii U #315

Closed GoogleCodeExporter closed 9 years ago

What steps will reproduce the problem?
1.Load a Mega CD game (tested with Sonic CD with proper WAV CDDA audio tracks) 
on WiiU
2.The game loads and both BGM and audio effects play
3.Try to collect two rings 

What is the expected output? What do you see instead?
Audio effects are expected to play in stereo, an audio effect for each of the 
two rings is to be played, however, only one ring is heard and the effect of 
the other ring (which normally comes from the other audio channel) is missing.

What version of the emulator are you using (official, SVN revision,...)?
1.7.3

Please provide any additional information below (Emulator settings, Console
setting,...)
Tested on Wii U's vWii and launched through the Homebrew Channel, Sound plays 
as expected on a regular Wii though, the missing audio channel in Wii U can 
also be noticed in the pre-game Sega copyright screen as well.

the ring sound is not made using cd hardware so i am not sure why you think it 
is sega cd specific issue ?
anyway, as you figured, stereo output has been tested and works fine on wii or 
gamecube so the problem is obviously not within my code but rather a wiiU 
specific issue. 

i don't have one so i can only make assumptions but this is more likely caused 
by a configuration issue (check your audio cables or wiiU audio settings) or an 
incompatibility between wii homebrew library (libogc) and vWii mode

in both cases, there is nothing wrong in the application itself and nothing i 
can fix
