Roku's dont support Multichannel PCM output (aside from MAT 2.0/Atmos with the 4800).So did some quick testing as I dont have a heck of a lot of time during the week. Roku's only support 5.1 output for Dolby, DTS and AAC (w/Dolby decoder output as DD5.1, though there is a bug currently). They arent supported in other formats at all (in any channel configuration). Notice it clearly indicates AC3/EAC3 and DTS are only supported in MKV, MP4, MOV (and AC3 and DTS respectively). If you read the support article (and the part I pasted), then you read this part:Īudio – AAC (.MKV. It seems Roku 3 does not support 5.1 flac files for DTS or Dolby Digital surround sound decoding. Therefore, the issue is not with the files or the receiver. I was able to play the flac files in DTS surround by bypassing the Roku and using my Sony blu-ray player instead. flac files that are 5.1 will not play in surround sound.
