Did a fresh install of Kodi on Debian 9 (stretch) from the repository. The sound is distorted. Any idea why?
I don't have ffmpeg installed and all the dependencies installed successfully.

I'm actually using Kodi from the stretch-backports repository. Namely 17.6.
Kodi has always worked well in the past from this repository.
I recently changed my hardware and the same version of Kodi I'm using now (17.6) worked fine on my previous (more-or-less similar) hardware. The audio DAC is a Realtek ALC affair and is something that's well supported under Linux and again been using for a few years (even with Kodi).
I don't have ffmpeg installed on the machine. I purged it. I believe Kodi uses it's own ffmpeg library if I'm not mistaken.
I have also tried another experiment. I purged Kodi completely and reverted back to 17.1 from the stable Debian repository. Unforunately the audio distortions are still present and they sound the same, in terms of pitch and harmonics.

If that's the case, problem is clear. The broken patched kodi in order to support old stretch version of ffmpeg. You can see the patch that breaks audio in the debian/patches folder
First decide what functions / features you expect from a system. Then decide for the hardware. Don't waste your money on crap.

Build from source. Debian's package is not supported out of that reason. ffmpeg 3.3 introduced an API change. Kodi 17.6 is only compatible with internal ffmpeg 3.1
Your choice :-)

I reverted back to 17.1 from the stable repository and the corresponding libavcodec57. Audio is back to normal.
It was libavcodec57 from bpo9 which was causing the problem for both Kodi 17.1 and 17.6.
