Hi,
some months ago, presumably after a kernel update, my system (archlinux)
started having the following problem.
After booting, it takes pretty much exactly 1 minute for the HDA Intel
PCH / Realtek ALC898 audio card and devices to become available.
Here's dmesg | grep snd:

At the 64 second mark, in this case, sound starts working correctly.

I tried adding snd_hda_codec_realtek to /etc/modules-load.d/snd.conf, in
which case lsmod | grep snd will be on boot exactly like after the 60
seconds, but I still have no sound and no ALC898 devices in aplay -l.
The journal contains nothing of interest, except that after the 60
seconds, it will print

Any ideas? I don't know how to debug this any further.
Thank you.
