Public bug reported:
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 sound is normal, as it should be. But system-wide the problem
persists.
