no sound with broadwell-rt286 HDA-Intel on Dell Venue pro 7140

I tried MXlinux on a Dell Venue pro 7140
no internal sound with broadwell-rt286 HDA-Intel
only Dummy and HDMI

Driver seems to be absent.
Any suggest for solution?

This has come up frequently on the MX Linux forum:


And that is where your question really belongs, since Xfce is not responsible for the OS. Try the Search function first, and don't forget to include the Menu > Quick System Info output that we will want to see.

MX-23 (based on Debian Stable) with our flagship Xfce 4.18.

Re: no sound with broadwell-rt286 HDA-Intel on Dell Venue pro 7140

I had to reinstall the system after big problems with unreadable and unrepairable data on the SSD. I tested different kernel versions in advance with live systems and found beyond doubt that higher kernel versions than 5.10.142-antix.2-amd64-smp do not recognize the sound chip - neither at boot nor by subsequent driver installation or other repair attempts. Support for these Intel Core M-5Y71 processors has been removed from the kernels, WHY EVER.
Therefore it took some time until I can thank you here for the support, which I do herewith.
The System works fine configurated as follows:
