Regarding the DIGITAL 5.1 sound I am not using Kodi, I am using BsPlayer to watch moves, I as always have. Regarding the Update I was able to perform it using a external drive since I didnt have space, the windows update itself asked for it so that part it solved. Hi Martin_HM, and thanks a lot for your answer since you helped more than Intel staff themselfs, which asked me several questions but did not provide me with any answer yet. The only time this doesnt work is when the audio is DTS-HD, since uncompressed HD audio (not to be confused with HD video) can only be transmitted via HDMI. your Sony Home Cinema) and the receiver will do the decoding, and show 'Dolby Digital' in the display. In this case the encoded (and compressed) multi-channel signal is sent to the receiver (i.e. Let the software send the un-decoded signal. If the software decodes the signal, then it will send a PCM stream via SPDIF, and since SPDIF if specified for 2 channel only, this will be a stereo downmix. You must not let the software decode the audio signal. I assume you are running Kodi or PLEX? Then look under audio settings.

Whether you see (I should say: hear) 2-channel PCM or 5.1 Dolby Digital depends on the settings of the HTPC software you are running on the NUC and on the system settings of the SPDIF output. To access the TOS-Link, you need a special Mini-TOS-LINK connector, which mechanically looks like a 3.5mm stereo connector. This jack houses both an electrical analog stereo output AND an optical Mini TOS-LINK output. Regarding Scott's note: This has nothing to do with the spec of the 3.5 mm jack. In layman terms, SPDIF basically is a optical system, which can transmit either 2-channel PCM or encoded multi-channel AC-3 = Dolby Digital. I'm running my NUC6CAYH in a similar setup, video via HDMI to the TV and audio either via HDMI as well or via SPDIF to the receiver. Hi Andre, I'm not Intel staff, but maybe I can help just a little bit:
