Audio problems on Windows 10/Kodi 17.1

Hello Forum,

I bought a Mini-PC for office use recently:

I wanted to use this tiny machine for Kodi as well but I have serious problems getting a proper/stable audio playback in my video files.

The Mini-PC is connected via HDMI directly to an older Samsung TV. The TV-set does not understand any compressed audio so any audio needs to be decoded to 2 channel PCM output.

Kodi runs smooth in general and video picture quality is excellent. However, I’m unable to make audio work.

In 4 out of 5 cases the video playback starts without any audible audio and then playback freezes after about 5secs.
After restarting Windows it sometimes work (with the very same files and no setting changed!). Then again some files later the same problem occurs.

It really doesn’t matter which codec needs to be played. Sometimes decoding works from mp3 to TrueHD(Atmos) and sometimes none of them work at all.

I tried every combination in the audio options dialogue in the last couple of days but none of them seems to work in the long run.

It tried DirectSound or WASAPI. The latter seems to be even worse. Because if there is audible audio it stutters awfully. While with DirectSound it works at least the aforementioned 1 of 5 times.
(And yes I ticked the check boxes in the audio device proberties to use it exclusively by applications, as mentioned in the KODI Wiki.)

Output is configured to 2.0 channels (in Kodi and in Windows for the HDMI digitial output)
Tried all three settings (Best match/fixed/optimum) for audio decoding settngs in Kodi.
Passthrough disabled of course, as the TV does not understand anything but PCM
Enabled/disabled sync audio/video to screen. No use.

My Windows 10 is fully updated.
Intel Graphics Driver is the latest version as well.
It’s a “Intel SST Audio Device (WDM)” in the device manager responisble for audio output. According to the device manager I have the latest driver for that installed as well.

Just out of curiosity i installed MPC-HC (Media Player Home Cinema) which I’ve been using for years. MPC manages to decode each and every audio track I throw at it without any flaws.

I also have an Android TV-Box with Kodi 16.1. All files that give me a headache on that Windows 10/Kodi 17.1 combo just work fine on the Android box.

I’m at my wits’ end here and would really appreciate some help. Thank you!
