No sound on Medion S2218

[hzulla]

Hi there,

first of all, thanks.

I'm trying to get a Medion S2218 ready for the kids. It still stubbornly refuses to work and I don't really know where to look for clues right now.

This is a default Ubuntu 18.04 installation, using an updated libasound2, blacklisted r8723bs and snd_hdmi_lpe_audio modules and the current UCM files from this repository's chtrt5645 directory.

Here's the output of alsa-info: http://www.alsa-project.org/db/?f=4e5aa7bf41fb0cb80d0b1ccddeebfa892c371321

There appears to be a proper soundcard setup, I can choose a device in the pulseaudio mixer, but there is no sound coming out of the device's speaker or headphone jack.

Thanks for any advice on how to resolve this.

I have re-installed a clean Ubuntu 18.04 and then updated to the current (pre-beta) 18.10, with a 4.17 kernel.

Blacklisted r8723bs and changed nothing else.

No sound, just a dummy device.

Now blacklisted snd_hdmi_lpe_audio too and still no audio.

I don't find much helpful advice, as this seems to be a rather rare device to install Linux on. Any guide on how to fix this would be welcome. Thanks.

There is still only a dummy audio output. Please advise on how I can help fixing this issue.

Here are some fresh diagnostics with an updated OS install, in the hope that they are useful.
