Hey! I did some expansion of the file formats we support on HiFi Streamer Pro!
Seems to work pretty good, surround sound works great in exclusive mode, it should try downmix if you are in shared mode, or it might just work, let me know if you test it out and run into any files which should have worked. I was going through tons of different formats of files and tested out every format and they work. There are even a handful of other ones which kinda work.

The museum formats I kinda got working were HTK, SD2, PRC, GSRT, CVS/CVSD, SNDR/SNDT, but you almost need adjustment settings for those to dial them in or something.
But basically if you throw an audio file at HiFi Streamer Pro now, it should work.
File size increase is mostly due to FFDShow bundling, I would haver made this an optionally-installed free DLC or something but we will probably need FFDShow for video playback anyway, so I'll just make it available and built kinda right into the app. We'll need it.
