Hmm you could be on to something.

A primary buffer is created with format=S16_LE, rate=44100, channels=2. I
believe these come from some default settings probably gotten from ALSA.

Then the buffer's format is set with SetFormat to format=S16_LE, rate=48000,
channels=6. None of this fails, but it does include a rate change.

Then there's a secondary buffer created with format=S16_LE, rate=48000,
channels=6. This is the one that never gets non-zero data during the intro
movie, but then gets data and plays it correctly during the main menu.

Finally another secondary buffer is created with format=S16_LE, rate=48000,
channels=2. This is the buffer that gets the intro movie data, which doesn't
get played out of the speakers.


With UseStereoSound=1, all of the buffers are identical to above, except they
all have channels=2 (and so exactly the same format). This works.

So maybe a problem mixing the 2-channel secondary buffer into the 6-channel
primary. Going to keep researching, but does that sound plausible, Maarten?
