To reduce the risk of speaker damage the PA gain needs to be limited on machines like the Lenovo Thinkpad X13s until we have active speaker protection in place.
Limit the gain to the current default setting provided by the UCM configuration which most user have so far been using (due to a bug in the configuration files which prevented hardware volume control [1]).

alsa-ucm-conf 1.2.11 was released yesterday, which means that it is now very urgent to get the speaker volume limitation backported to the stable trees.
Could you please try to make sure that these fixes get to Linus this week?
This series (and a related headphone codec fix) were merged into Linus's tree yesterday.
I saw that the 6.7.4 stable patches were sent out for review over night, but could it be possible to squeeze in also the following four fixes in 6.7.4 (and 6.6.16)?
c481016bb4f8 ASoC: qcom: sc8280xp: limit speaker volumes 4d0e8bdfa4a5 ASoC: codecs: wcd938x: fix headphones volume controls 46188db080bd ASoC: codecs: lpass-wsa-macro: fix compander volume hack b53cc6144a3f ASoC: codecs: wsa883x: fix PA volume control
These are needed for proper volume control and, importantly, to prevent users of the Lenovo ThinkPad X13s from potentially damaging their speakers when the distros ship the latest UCM configuration files which were released on Monday.
