My use-case is handling recorded AVI files which have an

allows to write an empty channel mask instead.
Are such files even valid?
I guess so as the docs at [1] say in chapter "Details about dwChannelMask":
"If, for example in a multi-channel audio authoring application, no
speaker location is desired on any of the mono streams, the
dwChannelMask should explicitly be set to 0."
BTW: I just noticed that FATE is failing after applying the patch so
I'll need to take a closer look and update the patch before it can be
applied.
