Can Plex Web Server play an .M4A audio file that has a bit rate of 750 kbps?

These are CDs I imported via iTunes with the Apple Lossless Encoder and it picked the bit rate. For some reason, after the library is scanned, these don’t show up in the library.

Also should mention that this is with the version of Plex Media Server that was posted on April 5 2016.
