FWIW Alpine edge branch has moved to GCC 15 (heading to Alpine 3.23), and reports [`bluez-alsa`](https://gitlab.alpinelinux.org/alpine/aports/-/blob/master/community/bluez-alsa/APKBUILD) 4.3.1 (for now) as one of many packages [failing to rebuild](https://gitlab.alpinelinux.org/alpine/aports/-/work_items/17311). Have not checked...

interesting in relation to https://github.com/revk/ESP32-Faikin/issues/299
