Recently I’m having an issue for which audio crackles when I run VirtualBox in Ubuntu 20.04.
If I then execute
pulseaudio -k it does fix it (upon restarting programs), but still this workaround is not great.
Sometimes (much rarely though) this also happens without opening VirtualBox, just by watching a video on Firefox.
I currently have the HWE kernel
5.8.0-59-generic #66~20.04.1-Ubuntu and my audio system is the onboard analog device as following (
card 1: Generic (HD-Audio Generic), device 0: ALC1220 Analog (ALC1220 Analog) Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: Generic (HD-Audio Generic), device 1: ALC1220 Digital (ALC1220 Digital) Subdevices: 1/1 Subdevice #0: subdevice #0
And this is what reported by
10:00.4 Audio device: Advanced Micro Devices, Inc. (AMD) Starship/Matisse HD Audio Controller Subsystem: ASRock Incorporation Starship/Matisse HD Audio Controller Flags: bus master, fast devsel, latency 0, IRQ 135 Memory at fcb00000 (32-bit, non-prefetchable) (size=32K) Capabilities: <access denied> Kernel driver in use: snd_hda_intel Kernel modules: snd_hda_intel
Not sure what to do next? How could I debug/investigate this further?
