If there is an EVM that meets all or part of the following conditions, I would appreciate your recommendation.
* I am looking for a possible EVM because I want to check whether a file that should not be played with SPDIF in due to license restrictions is played or not.
1.Is it possible to input the following file to USB IN and pass it through the SPDIF out jack with the same extension without PCM format decoding?
Also, is there any way to check the file extension that is being output to the SPDIF out?
ogg, mp3, aac, wav, mp4, m4a, aiff, flac, m4a,
2.Is there any way to check the extension of the file that is inputted when I input these files (ogg, mp3, aac, wav, mp4, m4a, aiff, wma, flac, m4a) into SPDIF IN?
