    Interesting.
    I have played this file on both my HD51 and GBue4k via hdmi into an Onkyo tx nr626 (which supposedly supports 4K passthrough but mostly doesn't!! ... but supports all the audio formats and allows you to monitor input & output streams)
    The ts file shows (mediaInfo):
    1 video stream @ 1920 x 1080i25 which plays quite happily at whatever output mode I set.
    1 audio stream AAC and another "menu" stream AAC. The 1st stream will produce good audio (English, 48.0 Khz, 2 channels, AAC (LATM) (LC) the other will not. So via your audio button on the Giga4K remote just check which audio stream you are playing.

    If I don't change defaults both the HD51 and Giga4K play audio that comes into the Onkyo as PCM stereo.
    On the Giga4K: (using menu/setup/audio & video/settings) ... using the audio button on remote doesn't seem to change anything
    If I enable AAC downmix, nothing changes -> PCM stereo.
    If I enable transcode to AC3 nothing changes -> PCM stereo.
    If I enable transcode to DTS -> DTS 2 channel stereo

    So I have no issue with the video stream and providing I select the "correct" audio stream that also works fine.

    So based on this the GB4K appears to not be the issue in your environment as I would expect PCM 2 channel stereo on the optical............... I will try the optical into my amp later if I can find my optical leads!

    OPTICAL!!
    So I have no issue with hdmi and the video stream and providing I select the "correct" audio stream that also works fine.

    Edit:!!
    So optical is different.
    I only get optical to work by setting transcoding to off and AAC downmix to Yes ........ then the Onkyo sees PCM 2 channel stereo. ... anything else and it doesn't recognise the audio input.
    Any use of transcoding with optical audio input................and no audio.

    So GB4K video via hdmi should work at any setting.
    GB4K and optical should work if set to downmix and transcoding off.

    this thread was not about the 4k receiver. I hope this doesn't get lost in the thread

    I was hoping it would do what it says on the tin 'transcode AAC to AC3' because sometimes BBC & Channel 4 broadcast programs with AAC 5.1. It would then come through the amp as AC3 5.1 not PCM 2.0. But thanks for testing and publishing your results.

    It would be interesting to see what the box does with AAC 5.1 (you might need PCM multichannel enabled). I was surprised at the difference in handling between hdmi and optical but more that AAC to AC3 didn't happen (especially when -> DTS does)
    As far as I could tell, OpenPli was just PCM. (I did try that image)
