Bug#959020: upgrade-reports: Soundcard not detected after upgrading to kernel 5.5.0-2-amd64 in testing

[Dennis <silverblue@justmail.de>]

Package: upgrade-reports
Severity: normal

Dear Maintainer,

since updating to kernel 5.5.0-2-amd64 #1 SMP Debian 5.5.17-1 (2020-04-15) x86_64 GNU/Linux my audio card is not
detected anymore. With kernel 5.4 the audio card was working and playing sound.

This is my card:
#sudo lspci -vv | grep -i audio
00:1f.3 Multimedia audio controller: Intel Corporation Smart Sound Technology Audio Controller (rev 30)
	Subsystem: Hewlett-Packard Company Smart Sound Technology Audio Controller
	Kernel driver in use: sof-audio-pci

Driver does not load:
#sudo dmesg | grep -i audio
