I did a fresh install of Win 10 on my friends laptop several months ago since it was outdated and lacked the space to do a upgrade. I believe I installed Win 10 1709 but the Win 10 audio driver didn't work, but luckily the 8 version did. Since updating to 1809 the sound has gone and there is no battery tray icon. It is grey out in Win 10 options.
There's talk about the matter on the Dutch page: https://community.medion.com/t5/Notebook-Netbook/Medion-Akoya-S2217-S2218-Windows-10-Fall-Creators-U...
Task manager doesn't even display 'audio input and output' in device manager so there's no id to look up.
