Pakker relateret til PulseAudio er blevet fjernet fra desktop- og desktop-minimal-pakkerne, og for at sikre kompatibilitet er der tilf\u00f8jet et lag kaldet pipewire-pulse, som fungerer oven p\u00e5 PipeWire og muligg\u00f8r, at alle eksisterende PulseAudio-klienter fungerer.       <\/p>\n<p>Beslutningen om fuldt skifte til PipeWire i Ubuntu 22.10 blev bekr\u00e6ftet af Heather Ellsworth fra Canonical. Det bem\u00e6rkes, at b\u00e5de PipeWire og PulseAudio blev brugt i Ubuntu 22.02. <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/da\/server\/dts-los-angeles\/\"   title=\"server\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"3816\">server<\/a> \u2014 PipeWire blev brugt til at h\u00e5ndtere video under optagelse af screencasts og til at give adgang til sk\u00e6rmen, men lyden fortsatte med at blive behandlet ved hj\u00e6lp af PulseAudio. I Ubuntu 22.10 vil kun PipeWire v\u00e6re tilbage. For to \u00e5r siden blev en lignende \u00e6ndring allerede implementeret i distributionen Fedora 34, hvilket gjorde det muligt at tilbyde professionelle lydbehandlingsmuligheder, eliminere fragmentering og ensarte lydinfrastrukturen til forskellige anvendelser.        <\/p>\n<p>PipeWire tilbyder en udvidet sikkerhedsmodel, der muligg\u00f8r adgangsh\u00e5ndtering p\u00e5 niveau med enkelte enheder og specifikke str\u00f8mme, og som forenkler organiseringen af lyd- og videopassthrough fra og til isolerede containere. PipeWire kan h\u00e5ndtere enhver type mediestr\u00f8m og er i stand til at blande og omdirigere ikke kun lydstr\u00f8mme, men ogs\u00e5 videostr\u00f8mme samt styre videokilder (optageenheder, webcams eller indhold genereret af applikationer p\u00e5 sk\u00e6rmen). PipeWire kan ogs\u00e5 fungere som en lydserver, der tilbyder minimale forsinkelser og giver funktionalitet, der kombinerer evnerne fra b\u00e5de PulseAudio og JACK, herunder at tage hensyn til behovene i professionelle lydbehandlingssystemer, som PulseAudio ikke kunne im\u00f8dekomme.      <\/p>\n<p>Hovedfunktioner:  <\/p>\n<ul>\n<li class=\"l\"> Optagelse og afspilning af lyd og video med minimale forsinkelser;  <\/li>\n<li class=\"l\"> V\u00e6rkt\u00f8jer til realtidsbehandling af video og lyd;  <\/li>\n<li class=\"l\"> Multiprocess arkitektur, der muligg\u00f8r delt adgang til indhold mellem flere applikationer;    <\/li>\n<li class=\"l\"> Behandlingsmodel baseret p\u00e5 en graf af multimediaknuder med underst\u00f8ttelse af feedbacksl\u00f8jfer og atomare opdateringer af grafen.
