Yes, but the layout is 3/1 as shown by mediainfo
Channel(s): 4 channels
Channel positions: Front: L C R, Back: C
This is also how the hardware Yamaha receiver will play the source DTS-
HDMA.
Hardware Yamaha receiver info with DTS-HDMA source: 3/1.
Hardware Yamaha receiver info with flac played back with kodi (ffmpeg):
PCM 2/2.
LAV filters plays it correctly as 3/1.
Thanks.
