Incorrect source value 'mp4'; correct highlighted value and retry

When I remove the mp4 entry, leaving only alac and flac, the error clears and all is well. I am also able to add mp3:wav24 and aac:wav24 just fine.

I've verified that I am running the latest version (update-35/0.8.1). I am also running the latest FFmpeg (2.3.3 for Mac OS).

Are you running MinimStreamer 0.4.1? In previous versions, the 'aac' source type applied to all files containing AAC audio (.aac, .mp4 and .m4a). The 'mp4' source type was introduced in MinimStreamer 0.4.1.

Quote:BTW, I can see how you get your interesting result of AAC better / MP3 worse. What I've learned with my Denon player is that there is wide variation with the quality of decoders in the embedded software and it's possible that your Linn DS is doing additional processing on MP3s that is skipped with AAC and WAV equivalents.

This might well be what is happening.
