A little bird once told me that the XMV format was on the horizon but
it was nothing but MS ASF containers with MS WMV2/WMV8 video and MS
ADPCM audio. So you may want to push the audio through FFmpeg's MS ADPCM
decoder and see what happens.
And if you can provide some samples for us to study, that would be useful.
