There's a bit of potential weirdness with the spa.alsa, seems to be
getting confused about accuracy, something I don't see on my 24.04
machine,

I subscribed alsa-drivers in case they have any advice. One other thing
to check, does the following sequence work as expected, or does the
volume clip to an extreme value?
$ pactl get-sink-volume @DEFAULT_SINK@
Volume: front-left: 53757 / 82% / -5.16 dB, front-right: 53757 / 82% /
-5.16 dB
balance 0.00
$ pactl set-sink-volume @DEFAULT_SINK@ -10%
$ pactl get-sink-volume @DEFAULT_SINK@
Volume: front-left: 47203 / 72% / -8.55 dB, front-right: 47203 / 72% /
-8.55 dB
balance 0.00
