Is there a setting to turn on a sound for the arrival of a chat message?
At this time, the ability to notify chat activity with a sound is not available for the Windows client.
I would definitely suggest creating an idea for this and getting the community to vote it up!
What OS and what Lifesize client are you referring to?
I am using Windows 7 professional with service pack 1.
Lifesize Cloud Version 220.127.116.11397
There was an issue with audio chat notification in MacOS, it was corrected in the latest update of Cloud client. I am running 9.0.107 on MacOS.
I do not know if this feature is also available on the Windows client. Maybe some Windows users could contribute here?
