The Upgrade (via dvd) from 15.3 to 15.4 had some of the same problems as
from 15.2 to 15.3, but the solutions were the same as well. There is
only one new problem:
Sound aka Audio. I have the speakers plugged in to the back of my PC,
they don't work under 15.4. The workaround is to plug headphones into
the appropriate front socket - that works - and then to unplug them
again, at that point the speakers spring to life.
If I then put the PC into Sleep mode and wake it up again, all is fine.
If I then reboot, back to square one.
Since the wake-up process after Hibernation does not work (not that I've
tested it recently), I can't say what would happen then.
Audio device: AMD Kabini HDMI/DP, Kernel module: snd_hda_intel

The Kernel module being used feels rather inappropriate, not least
because this is an all-AMD system (the MoBo is Asus).

Oh, and another difference between Leap 15.4 and the two levels
preceding it: "Recent Files" does not include directories any more.
This was the behaviour up until Leap 15.1 (I think) and something which
had really annoyed me when it changed.
@Carlos, since you don't use the kde desktop this is not your area of
expertise, or at least that is what you said a couple of years back when
I commented on the change.

addendum: According to YaST2 the "Kabini HDMI/DP Audio" device is
unused, it says the sound card in use is "Family 15h (Models 60h-6fh)
Audio Controller".
The A320M-K MoBo description says "Realtek ALC 887-VD2 High Definition
Audio CODEC".

What does it suggest that the SLE codebase commonality allows, among other things, the discretionary migration of enterprise users to OpenSUSE? The last time I read something similar was when Netscape was about to relinquish its proverbial browser to its fans.

2
My community internet connection is so poor that it should really hide like dogshit in tall grass, so I'd be game for a subscription service whereby OpenSUSE could get additional funding by sending me a Leap frisby on each release (no 3rd parties, I wouldn't trust those for binary code).

3
How about offering depersanalised virtual complete images of users' actual installations for download and installation with the release frisby? This could resemble the kde system of users providing look-and-feel packages. Listing could show the desktop capture, the principle mission/package setup offered by the submitting user, and the required partition size. Suse could decide submission format requirements and filter for the best hundred or thousand submissions. A very easy installation and a clear preview could get more newcomers to the reppos. When I started out with Linux the biggest obstacle by far was the installation complexity (because unlike windows it involved a lot of choices like disk configuration). This turnkey image method would let beginners dowload a ready image and just boot it. The packages, being mostly just configuration would not require that much 'additional' space.

Which is the part that uses the intel driver, I believe.
I was told recently that that particular driver handles a lot of hardware.
