When I configure my default sound card in YaST2, the configurator creates the file /etc/modules-load.d/yast.conf -- the file contains the name of the sound card driver: "snd-hda-intel".

While this may sound innocent enough, it is not: modules-load.d seems to be an incorrect way to load the sound card driver. When this yast.conf file is there, it causes the system to attempt loading the driver at the wrong time or in the wrong way. The result is that sound is disabled after boot (no sound cards recognized), and so has to be activated manually with modprobe. Doing so works well enough, it just won't happen as part of the boot sequence.

This only happens, however, after regeneration of initrd (which is not triggered by YaST). In other words, you can reconfigure your sound card, and everything looks fine -- until the next system update that triggers mkinitrd. After that, the sound card will go south in the way described.

The cure for this problem is simple enough once you know it: Remove the file /etc/modules-load.d/yast.conf, then run mkinitrd.

Suggested fix: YaST2 should not produce this file. It seems to be an obsolete thing that has resurfaced, perhaps due to a code regression?

Reproducible: Always

Steps to Reproduce:
1.Configure default sound card in YaST
2.Execute mkinitrd
3.Reboot
Actual Results:  
The file /etc/modules-load.d/yast.conf is created by YaST. After execution of mkinitrd, the sound card boot sequence will be broken, resulting in no available sound devices.
The problem is somewhat aggravated by the fact that mkinitrd will not necessarily occur immediately after the faulty sound configuration happened. If mkinitrd occurs instead upon the next system update where it is required -- whereupon the error becomes apparent -- it will be quite difficult to isolate its cause.

Expected Results:  
YaST should not be creating the /etc/modules-load.d/yast.conf file - so that the sound card remains functional even after a subsequent execution of mkinitrd.
