Hm, there shouldn't be a change regarding the volume control.
There can be an issue about PCM stream, e.g. in commit
eb541337b7a43822fce7d0c9d967ee149b2d9a96
ALSA: hda - Make converter setups sticky

To be sure, could you try to revert it? If it doesn't help but still
you get strange volume behavior, please get alsa-info.sh output at
different volume levels for comparison.
