Hello Debian maintainer, i don't want to criticize you, but there is no progress in this and other bugs like this any more. The problem is that i am still working with Debian 8 (Jessie) on my desktop, because there are fundamental problems in Debian 9 & 10 desktop systems that will prevent to use ist, like a missing sound.
It's not a problem to use newer versions of Debian in server systems, because there is no need of a desktop. But when you want to have Multimedia and other features like working with 2 screens then only Debian 8 is working with all features. I think this is not your fault - is it possible that newer Versions after Debian 8 (Jessie) are not as stable as the years before any more? It's like a step back to the roots in the history, where video and sound problems are a nightmare after each upgrade of a system. When you agree, what can be done? Best regards karsten
