Hello there,

The Sims 1: Unleashed makes use of WVE files for its intro videos.
Two of the files for the game use Mono ADPCM audio instead of Stereo.
However, FFmpeg's ADPCM_EA codec always expects the files to be in Stereo.

In addition, they're supposed to play at 30 fps, but the EA demuxer assumes
15 by default.
It appears the framerate is set with the use of the 0x1B code in the SCHl /
PT00 header.

I have made changes in the patch attached to fix these problems.

Thank you!
