Hello,

I reverted the kernel source in the directory sys/dev/sound/pci/hda to r342378:

$ cd /usr/src/sys/dev/sound/pci
$ svn info hda
Path: hda
Working Copy Root Path: /usr/src
URL: svn://svn.freebsd.org/base/head/sys/dev/sound/pci/hda
Relative URL: ^/head/sys/dev/sound/pci/hda
Repository Root: svn://svn.freebsd.org/base
Repository UUID: ccf9f872-aa2e-dd11-9fc8-001c23d0bc1f
Revision: 342378
Node Kind: directory
Schedule: normal
Last Changed Author: mav
Last Changed Rev: 340071
Last Changed Date: 2018-11-02 18:02:10 +0100 (Fri, 02 Nov 2018)

compiled and installed the kernel:

$ uname -a
FreeBSD c720-r368166 13.0-CURRENT FreeBSD 13.0-CURRENT #1 r342378:368166M: Fri Dec 11 07:46:32 CET 2020     guru at c720-r368166:/usr/obj/usr/src/amd64.amd64/sys/GENERIC  amd64

and all is fine again as it was before. Someone with more knowledge should
have a look into a 'svn diff -r342378:368166 sys/dev/sound/pci/hda' and
see which of the changes might break the things. 

Thanks

	matthias
