Noise on DAR
Hi
I 'm using DAR on a 2nd computer (Mac Mini ) with 64 i/o from dante virtual card and everything is working fine as expected
Now i'm trying to use DAR on my 2nd PC instead of Mac with the same configuration but i'm getting weird noise from
DAR.Is this a known windows issue?
Thanks
John

    Hi John,

    This can certainly work. Can you verify that the sample rate is consistent in the Dante Controller device view? Noise can often be a result of mismatched sample rates.

    Also per the installation and configuration guide Section 7 make sure the optimization have been set: turning off the sound scheme etc. The guide will be installed and can also be found here:

    Best,

      Hi Adam
      Thanks for the reply. The sample rate is the same on both devices .I tried all your suggestions but nothing works !
      The noise is some kind of pink noise coming from the renderer even when i play a previous recorded ADM file !

    Although this is happening only with the renderer .Everything is working fine if i just play audio files from one pc to the other .For example i can route audio from nuendo on the 2nd pc to pro tools on the first .That means that Dante routing is working fine
    Thanks

      Is the pink noise in both Binaural and Speaker output from DAR?
  • AdamP (Dolby Labs)

    Hi,

    So this is noise playing over program when you playback an ADM or just noise and no program at all? Per the question above is this coming out of the speaker outputs, headphone outputs and/or re-render outputs? The headphone and re-render outputs would need to reset from their default values in the Room Setup window to use the outputs following the speakers. Can you share a screengrab of the Renderer device settings? Also if you can zip up the logs file accessible from the help menu I'd like to see if there are any errors. Lastly is the Dante Latency in the Dante Virtual Soundcard set to 10ms or shorter?

    Thanks,
    Adam

      Hi Adam
      The noise is coming from all the outputs with no program at all.I'm attaching a screenshot of my settings .Re-renderers are off pink noise is off ,sample rate is the same on all devices ,latency on dante virtual soundcard is 10ms.
      My routing is the follow : From main pc i'm sending audio to renderer on my 2nd pc via dvs ,then the renderer out is routed back via dvs to my Focusrite Red 16 Line which is feeding my speakers and is connected via thunderbolt on my main pc .This setup works perfectly when i'm using my Mac mini as renderer host but not when i'm using my 2nd pc as host .I think maybe some conflict exist on windows between renderer and dvs .
      I will send you the logs too in a second post
      Thanks,
      John

    Headphones are on out 17-18 an re-renderers are starting from out 19 when are on

    Hi John,

    The only errors I see are timecode via Asio and audio device selection errors. I'm not in front of a system right now but remotely looking at meters routed from a PC with DVS to my monitoring system I'm seeing clean playback and only signal on channels with the generator running and no noise. Can you confirm you Renderer and DVS settings are as pictured in the attached and following post?

    Thanks,
    Adam
