I placed a phone call this morning using Google Voice which I have as a pinned tab in Firefox.
I was watching Activity Monitor and noticed that coreaudioid was running and using 13-15 percent CPU so I started closing applications to see if there was something causing it. I eventually closed Firefox and coreaudioid went away. I restarted Firefox and it still was gone. Then I started a call using Google Voice but didn't actually connect and it came back and was using about 5% CPU. Then I reloaded the Google Voice page and it went away. (coreaudioid normally always runs but it's not in the topcpu display normally unless I'm running something with continuous audio output)
So potentially a bug in Google Voice or Firefox. But I have a workaround now.
15% CPU is not a big deal on an M1 Pro MacBook Pro but it's nice to keep it clean.
I wonder if there are other programs or webpages with this issue.
