You have been subscribed to a public bug: I'm using a Raspberry Pi 4. After updating from Ubuntu 20.10 to 21.04, I noticed audio problems. The sound is slow and crackling.
I'm using the headphone jack and the config.txt option: dtparam=audio=on If I start a video or audio file in VLC player and select the VLC options: Audio: Output module: ALSA Audio Output Device: bcm2835 Headphones, bcm2835 Headphones Default Audio Device Then the playback speed seems to be normal but the "electric" crackling in voices remains. And system-wide the problem persists, too. ** Affects: pulseaudio (Ubuntu) Importance: Undecided Status: New ** Tags: bot-comment raspi -- (Ubuntu 21.04) RPi4 audio is slow and crackling https://bugs.launchpad.net/bugs/1926906 You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to pulseaudio in Ubuntu. -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
