#20477 new defect

log spam/constant high cpu usage related to audio

Reported by: gl Owned by:
Component: audio Version: VirtualBox 6.1.22
Keywords: Cc:
Guest type: Linux Host type: Mac OS X


I can see constant high cpu usage due to logging, in the virtualboxvm and logd processes on the host but possibly a genuine problem with the audio subsystem somewhere.

When I look at the logs, it keeps spamming it with:

buffer 0 ptr 0x7fe11a313f5c size 0

It's coming from audiotoolboxcore.

one more thing to note, I killed pulseaudio on the guest, and the cpu usage on the host dropped accordingly. Before I killed it, I checked the cpu usage on the guest, the diagnostics from the guest suggested that pulseaudio was not using much processing time.
