After installing pipewire, volume always set at 92% on login?

All, I finally took the plunge and installed pipewire on 15.4. Works just fine. Just install per https://en.opensuse.org/openSUSE:Pipewire and you don't have to enable the systemd unit -- it will be done. Anyway, one strange side-effect is that on boot/login (like after today's kernel update), the volume is always set at 92%. Way too loud. I always set the volume to 57% or 62% which is about right on this laptop. What tool or what config file do I use to tell pipewire to either set the volume at 62% or just not touch the volume setting altogether? -- David C. Rankin, J.D.,P.E.
