Thus, when you add the sound library, it can't escape the snap environment and always fails to play or detect the mic.\n\n### snippet\n\n```\nimport processing.sound.*;\n\nvoid setup() {\n  Sound.list();\n}\n```\n\n\n### Additional context\n\n\"PortAudio is not supported on this operating system/architecture\"\n\"Sound library: Didn't find any output devices with the default driver, trying PortAudio...\"\n\npavucontrol works fine, but processing never appears as an application.\n\nDuring the debug process I've also run:\n\nsudo apt install portaudio19-dev libportaudio2 libasound-dev\nsudo apt install libpulse-java\nsudo apt install pulseaudio-utils\npulseaudio --start \n\nAnd restarted etc, no change.\n\n### Would you like to work on the issue?\n\nno","author":{"url":"https://github.com/Luke2642","@type":"Person","name":"Luke2642"},"datePublished":"2025-05-07T10:09:23.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/1078/processing4/issues/1078"}
