"cannot communicate with audio interface" errors with PT 2021.10
 

I am running at 128 samples, with the optimize performance box checked.

Honestly, I never had an issue like this until the recent firmware update coinciding with the preamp control release that I just updated to.

I am now getting "cannot communicate with audio interface" errors at least once an hour. I have to shut down pro tools and restart it every time.

M1 Mac mini with 16GB ram. Any thoughts?

Damn, I’m glad I was out of town when the update was dropped. Keeping an eye on this thread before I update to 2021.10 and Carbon FW update.

Yes I have had this error a couple of times
And also when using a VI at lower buffers I'll see how unchecking optimize works and jump to 128

Re: Communication problems between Carbon and Pro Tools
 

Im using 128, and I have this issue. I might trying lowering the buffer to see if its worse.

Re: Communication problems between Carbon and Pro Tools
 

Is the error there at normal buffer sizes (256+)?
I'm waiting on updating at the moment, due to this thread. Don't use VIs, but do need Carbon to not disconnect during seasons with session players.

Yep, I received and I am working with the support team on a resolution.

Thanks

Hello all,

I am having the same issues…

I updated to the newest firmware yesterday (with remote control Carbon pre GUI)
I am having the same problem, the Carbon repeatedly looses connection with pro tools and I have had to quit and restart several times in a couple hours.
I never had this problem before the update.
I am running at 256 H/W BUFFER. Session is at 24/44.1k. should I be running at a higher buffer? Would that change the low latency performance if the lightning bolt is selected on my tracking channels ?

Thank you !

Please keep us in the loop, as I hope they will fix this bug. In the mean time I'm not upgrading to the lates FW and Protools Update.
Thanks.
