 Summary of the bug:

 mpv sample.mkv -ao=pulse -audio-spdif=truehd

 While playing this video file with truehd atmos audio, audio cuts always
 on the same spot, 100% reproducible every time giving the following
 message.

 [ffmpeg] spdif: Unusual frame timing: 10248 => 12042, 40 samples/frame is
 not implemented. Update your FFmpeg version to the newest one from Git. If
 the problem still occurs, it means that your file has a feature which has
 not been implemented.

 I compiled and tried latest ffmpeg git and mpv git with same results.
