Yes, this is due to the fact that the Control Room routing for Talkback requires processing to be routed and is therefor, latent. One workaround is to do an audio track for your Talkback and turn on Monitor Enable as needed. Personally I haven’t found it to be a major issue because the performers can’t hear me in the first place, hence their need for Talkback, but I did have another customer with a UR who had the same issue.
