I switched about three months ago from pulse to pipewire. Since then I've been experiencing no audio output almost every day I resume my laptop from suspend (s2ram). I did a few tests: reinstalled all the pipewire packgages, removed configuration directories, upgraded to latest available version (Manjaro = 0.3.34). So far nothing did help. The only I can do to fix this is restart the pipewire services. I'll wait for 0.3.35, but if the issue still persists then I'll switch back to pulse...
