Our codecs are fed by external DSP devices that perform the microphone mixing - we however let the codec do the echo cancelling, and prior to TC7.1.1 didn't have any issues - it's only since TC7.1.1 that we've had these error messages, and in some cases, the additional delay it has magically decided to add to the systems has caused problems. I'll open a case with TAC tomorrow so I can obtain a token to access the "remoteuser" account and let you know what happens. I suspect that is caused by the DSP - which causes the codec to "spit the dummy" - which is interesting since there's no such issue in versions prior to TC7.1.1 - so you guys must have introduced a new "feature" in TC7.1.1 "The key point in this warning message is that we have detected a very high latency in the "acoustic" loop from loudspeaker output to microphone input." Yes, we use a relatively large number of microphones and speakers with these sysrems, so the Nexia handles the lot - and we have not experienced any echo, or other audio related issues, audio is perfect - despite what the warning is telling us. If that is the case, you have to turn off the echo-canceller in the codec in order to not get any echo or other related issues:" "I assume that the acoustic echo canceller is done in the external DSP. Yes, and we do use HDMI for video in our meeting rooms, but that's for video only - we don't use HDMI for audio anywhere at all as we always use external, powered speakers, and the warning does not pop up on any of those systems, but there's no external DSP in play either, so

"The most normal use case is a codec connected to a TV monitor via HDMI"

Can you please try out this configuration and post your feedback here? That would be very helpful. You should not experience any echo issues after doing this. sys-ttpar set-litr Audio/Configuration/EcReferenceDelay/Mode Auto ( = default).xConfiguration Audio Input Microphone 1 EchoControl Mode: Off.

If you do that, you will also get rid of the annoying warning. XConfiguration Audio Input Microphone 1 EchoControl Mode: Off If that is the case, you have to turn off the echo-canceller in the codec in order to not get any echo or other related issues: I assume that the acoustic echo canceller is done in the external DSP. Jens, in you case it is a bit different since you are using an external DSP.

We recommend to set the TV monitor in PC or Gaming mode in order to reduce the latency to an acceptable level. TV monitors may introduce 100 - 200 ms latency. The most normal use case is a codec connected to a TV monitor via HDMI. This latency is introduced out of our control either in the loudspeaker path or in the microphone path and gives a not optimal user experience for real-time communication.

The key point in this warning message is that we have detected a very high latency in the "acoustic" loop from loudspeaker output to microphone input. We are currently working on a modified text for this warning to hopefully make it less confusing. Please remember to rate responses and to mark your question as answered if appropriate. I've also been told that the Delay will be reset to 0 on SX20 endpoints when disconnecting and reconnecting the microphone with TC7.2 (which hasn't been released yet). I believe there is a bug open for this, although I don't have permission to see it: CSCul15840 I still see it as a workaround as the issue wasn't there prior to TC7.1.1 and there's obviously something new in those releases that have caused this to occur. This has removed the warning message and resolved some of the echo issues we experienced on our endpoints.

I've logged a couple of calls about this and the answer so far has been to request the password for the "remotesupport" user through the TAC (with the token generated from the endpoint) and then to log in and issue some commands to turn the EcReferenceDelay to 0 (and set it to Fixed):ġ) SSH in to codec and log in as remotesupport We've seen the same here on quite a few of our endpoints.
