    White noise through monitor speakers on wake-up

    When Ubuntu resumes from sleep, I sometimes hear white noise from my monitor speakers. Sometimes this is accompanied by screen flicker. I can clear both by switching to a different TTY and back (CTRL+ALT+F1 then F2), which suggests it is a driver / software issue, not a hardware breakdown. Can anyone help diagnose and fix this?

    Ubuntu 20.04
    Graphics card: Nvidia TITAN RTX/PCIe/SSE2
    Nvidia driver version: 440.100
    CUDA version: 10.2.
    Connected by DisplayPort to BenQ BL2420PO monitor.

    Welcome.

    You may try a newer Nvidia driver if it supports your card.
