[alsa-devel] Regression: very quiet speakers on Thinkpad T570s

Hi,

Some folks have reported on the Fedora bug tracker[0] that the laptop speaker volume is very low on the Thinkpad T570 when running a kernel that includes commit 61fcf8ece9b6 ("ALSA: hda/realtek - Enable Thinkpad Dock device for ALC298 platform").

alsa-info.sh from v4.15.4 (just before commit 61fcf8ece9b6 arrived in stable) and v4.19.4 with the issue present are attached to the bugzilla. I've also Cc'd Tim, who uploaded them and has the laptop in question.
