Find the right model for your box:
/usr/share/doc/kernel-doc-*/Documentation/sound/alsa/HD-Audio-Models.txt

Make a /etc/modprobe.d/hda-intel.conf

Fill it with:

options snd-hda-intel model=<yourmodel>

That helped me to workaround the same issue until it was fixed
upstream and until the fix was finally downstream in Fedora (the
latter was the time taking part).

Hope it helps you too.
