Audio Dropouts When Using Rendezvous

Does anyone have issues with audio dropouts when using Rendezvous?

I produce a show remotely, and the audio drops out completely for brief blips at random moments. Yesterday's stream has an example at the 44-second mark: https://youtu.be/2ywkh5_10VM?t=39 (and then throughout).

This occurs both on the recorded local file and the live stream (though I don't hear it while monitoring live.)

I'm using 14.1.2 on an i7 iMac with 32GB of RAM and Catalina.

Any insight is appreciated.

      Dom Bagnato There can be many causes.
      What browsers are the guests using?
      Do the guests hear any audio dropouts at any point?
      Are you monitoring guest audio in Rendezvous Dashboard?
      Do you hear the dropouts there?
      What macOS are you using?


      We'd need enough information so an engineer can duplicate everything about the call.

  • All guests are using Chrome, as am I. Three guests use PCs and one uses a Mac. I'm using a Mac running 10.15.7.

     

    None of us having any issues hearing each other within Rendezvous while we're talking to each other live.

     

    We only hear dropouts on the live stream from a viewer's perspective and also on the local recording after we're done.

     

    Thanks.

      Dom Bagnato Thanks.

      Please generate a Rendezvous log we can examine.

      Hold Shift key and open Wirecast > Preferences.
      You'll see a Debug tab. Go to that and enable Rendezvous Logging before making your next Rendezvous call.

       

      Assuming the dropouts happen again, the next step after stopping the live stream and/or recording would be to generate a report.

      If you have an example where the dropouts are obvious please send a link to that.

      Open Wirecast > Help > Send Support Information... and use the Save Report button.
      Then attach that report to a post in the forum (or you can provide a link to it and use the Forum Private Message system).

      That log will give us details about the Rendezvous call and what might be causing the dropouts.

     Just to make sure this is a Rendezvous issue and not some other audio issue can you run a test using only a local source (Mic). Since the Rendezvous guests sound fine in Rendezvous perhaps there's a separate audio issue occurring that may impact any audio source.

  • Thanks. I just made a local audio recording with my mic, and it works fine. I turned Rendezvous logging on and should be able to share the report on Tuesday. (Shows are on Monday nights.)

     

    Have a great weekend,

     Thanks. The test confirms that Rendezvous may be the issue and the logs may show us what and why.

    • CraigS  Here are the log files. I accidentally quit the program before saving the report, but I'm hopeful that this logs everything since I turned on the Rendezvous logging.

       

      Thanks for any help that you can give.

      Dom Bagnato Developers would like to know what your CPU% when streaming and recording. Also they'd like to know your specific iMac model as i7 can be as old as 2010.

  • My CPU fluctuates, but I don't think it ever goes over about 40%. I'm streaming and recording locally simultaneously.

      Dom Bagnato Thanks for those details. If you test with one guest only do you still have the problem? Investigating that multiple guests may be a factor.

      Like
  • I know that the problem existed when we only had three guests, but I'll have to setup a single guest and record locally to test that.

     That would be important for us to know. It could be a clue where the issue might be. Thanks in advance for testing that.

      CraigS I just recorded with one guest for about 9 minutes. There was only one audio dropout, but that seems likely to have been an anomaly or bandwidth-related. It definitely wasn't the persistent dropouts that I'm getting with four guests, so you may be right to investigate an issue with multiple guests.

       

      If it is an issue with multiple guests, do you have any suggestions or a timeline of when this might be fixed? I'm getting pressure to try alternative streaming solutions, and I'd really rather not go that route.

       

      I'll also attach the log for this call here.

      Dom Bagnato Thanks for doing that. That gives us something to compare it against.

      We can't give a timeline yet until we can confirm the cause. Issue could be Wirecast or WebRTC backend based or something else.

      Dom Bagnato Developers still looking for more details.

      • Do you have a "simple" document? Are they just using Rendezvous guests or are there a whole bunch of other shots / layers in use?
      • When in the single guest environment, what is the guest's setup?
      • When in the single guest environment, is the guest using a USB device, or the built-in microphone?
      • What is the CPU usage of the entire system when using Rendezvous (and observing dropout)?
         
      Like
    • CraigS 

      1. The simplicity varies, but there are always at least a few other shots in the show. Those additional shots are mostly still PNG files though.
      2. The single guest used headphones and an external USB mic.
      3. See above.
      4. The CPU usage with the dropouts is around 40%.

      In case it's helpful, when observing dropouts:

      • Two guests use headphones and USB mics. Two other guests use Apple headphones with the mics that are built into them. No one is ever using mics built into their computers.
      • In all cases, as the Rendezvous director, I'm using an external mic and headphones. My audio is heard within the Rendezvous dashboard, but I don't send it to the show.

      Thanks,

    • CraigS Thanks, Craig. I think the 14.3 Beta made the issue a little better, but there are definitely still some audio dropouts.

       

      I'm not sure what you try next. I did watch the CPU percentage a bit more this week, and it did reach up to 50% a few times -- though I'm not sure that the dropouts correlated to those times.

       

      Do you think lowering the encode quality to 2 might help? Or is there something else I should try?

      Dom Bagnato Are you using any Bluetooth headsets or any Bluetooth audio devices at all?

      If so, eliminate Bluetooth devices and see if that improves things. They're wondering if "Apple" headphones might be a factor along with other Bluetooth devices. 

      Like
    • CraigS One person does use Apple's AirPods for his speaker and a Blue Yeti for his mic. Two other users use Apple's wired headphones with built-in mics that came standard with older phones (so 3.5mm jacks, not lightning).

       

      I will ask the person who uses AirPods to try wired headphones this week. Could this be causing the issue even if the dropouts are across users (and not specific to that AirPod user)? The dropouts occur across all users at random moments.

      Dom Bagnato We're wondering about some odd Bluetooth combination since we have no other customers reporting a similar issue. Thinking that even a Bluetooth monitoring combo might be a factor.

    Shouldn't have any impact on Rendezvous where this issue is.

  • Thanks,  CraigS . Removing the Bluetooth AirPods from the equation did seem to help significantly. It may be completely solved, but I'm waiting for one more show to be sure. Here's the resulting episode:

    • CraigS No. I was never using Bluetooth. One of the remote guests was using AirPods for his own audio along with a Blue Yeti for his mic.
