Hi
Recently I've encountered this error and as Hans de Goede's request I'm reporting this back to you. This happens while booting my laptop connected to docking station and without using one.
kernel: WARNING: CPU: 1 PID: 330 at sound/hda/hdac_component.c:290 snd_hdac_acomp_init+0xde/0x130 [snd_hda_core] There are 2 more "cut here", but they're almost identical so I've only included one in this email.
Don't know what will be valuable to you, but I'm willing to help test this and do what I'm told. So, how can I help?
More info about this particular kernel and issue, that led to this is at: https://bugzilla.redhat.com/show_bug.cgi?id=1757891

This should have been already fixed by the recent commit 5a858e79c911330678b5a9be91a24830e94a0dc9 ALSA: hda - Disable audio component for legacy Nvidia HDMI codecs which is already included in Linus tree. Please check it.
thanks,
