--- Comment #4 from Rémi Bernon <rbernon at codeweavers.com> ---
The main difference is that the Linux version of FAudio, provided by the Linux
distribution, was previously used, and it was generally built with assertions
disabled, where Wine now uses its own PE version of FAudio, which has
assertions enabled.

That assertions may be genuine or not, and I believe it comes from a difference
between calls to X3DAudioInitialize with a channel mask, and to
X3DAudioCalculate with a channel count which doesn't match the initial channel
mask. It'll probably require some tests to validate whether it should assert or
not.
