Receiver 12.9.1 - High CPU 10% - coreaudiod

[Tom Matthews]

I often use Citrix Receiver to work remotely (and so often without a power connection for my laptop),

therefore I'm quite aware of processes using lots of CPU and hence battery power.

 

Whenever I'm connected, Activity Monitor show coreaudiod consuming ~10% CPU (frequently the top consumer).

 

The Receiver logs are filled with many thousands of these lines (50 per second!) :

This happens even if I disallow connection of microphone to the connection.

 

Please help!

Perhaps related, lots of 'wakeups exceeded' system reports are being generated :

This is still an issue for Citrix Viewer version: 18.9.0.323 (1809).

Any sound delivered by Citrix Viewer from the target system, causes coreaudiod to consume ~10% CPU.

Still high on these days!

Workspace Version 20.02.0.5 (2002) on a new MacbookPro 16" with i9 and 8 Cores. CPU consumption sometimes 22%!

Also seeing this issue still in Workspace 2007. Hoping for a fix from Citrix?

[Slava Tsarev]

still a problem with Citrix Viewer of Version 21.04.0.14 (2104), running on Macbook Pro 16" macOS 10.15.7 (Catalina)
