Alpine base snapcast no longer work

I've tried it with:
FROM python:3.9-alpine

ARG LIBRESPOT_VERSION=0.5.0-r0
ARG SNAPCAST_VERSION=0.28.0-r1
It builed an image, but snapserver has errors!
I have to change to Debian base image for use but I don't like it much, because the image size bigger than Alpine!
Have to wait...
