Ved opstart af PulseAudio eller ved hot-plugging af kortet, blev modulen module-alsa-card nogle gange markeret tilg\u00e6ngelige profiler som tilg\u00e6ngelige, hvilket f\u00f8rte til valg af profiler med ikke-fungerende output. Tidligere blev en profil anset for at v\u00e6re tilg\u00e6ngelig, hvis den indeholdt en modtager og en kilde, og mindst \u00e9n af dem var tilg\u00e6ngelig.
