Incompatibility between musl and pulseaudio

Describe your issue

There's an incompatibility between the musl version 1.2.4_git20230717-r4 and pulseaudio on Samsung Goyawifi ARMv7.

Downgrading musl to the 1.2.4-r2 makes the pulseaudio to run properly. Logs attached at the bottom.

What's the expected behaviour?

Pulseaudio should load and don't give an error, as it does with older version of musl.

What's the current behaviour?

Pulseaudio is crashing with Failed to handle SIGBUS.

How to reproduce your issue?

Using edge version of pmOS on Samsung Goyawifi with pulseaudio installed and try to control the sound or play audio.

What device are you using?

Samsung Goyawifi.

Linux samsung-goyawifi 3.4.5 #3-postmarketOS SMP PREEMPT Thu Mar 16 23:04:50 UTC 2023 armv7l GNU/Linux

Thanks for the report! In general, these things should be forwarded to alpine. But since maybe this could be some kernel issue (that kernel is ages old), let's wait for that. You say, that things are fixed with 1.2.4-r2, but there were very many builds in between that version and current. It would great if you could bisect which is the exact version that reproduces the issue for you. Otherwise the chances of this getting fixed are quite low.
