Pipewire is being the default supported audio standard and some editing and audio processing apps have dropped support for its pulse variants due to latency, eventual migration is planned?, as an important option from jamesdsp (the program I use for headphones) already stopped working on flx1s while it still works normally on the flx1 I can no longer use as a phone
Haven't tested yet, but you could give a try to installing `pipewire-audio` and `pipewire-pulse` packages, then deleting anything with `pulseaudio` in its name, and rebooting. I was able to use this method to migrate standard Debian from PulseAudio to Pipewire, but I'm not sure if it will work on FuriOS due to Halium stuff (I don't know how Halium will react to pipewire and if it even supports it).
