Dante's Inferno

I just installed the DANTE virtual sound card on my m1 Mac and am feeding a Dante AVIO AES adapter.

It mostly works but I get these pauses mid track.  It happens with Apple Music and with Audirvana.  Anybody have a debugging method that might help.  I have not tried contacting anyone else yet.

Oh and it does sound good.  But the AES is hot...

I love it Bob! Bringing HiFi into the next century. 
 

How is the AVIO connected, through a switch or straight from the Mac? Are there options in the driver for frame size or latency or anything?

The AVIO goes through a POE af (ubiquity) back to the USW16 switch.  The Mac does the same.  There is some latency control in the DVS software I can set it 4, 6, 10 ms the AVIO is 1ms I have not found any settings yet.

Just sharing my learning and frustration. 

The AVIO is up to date according to the firmware check but it is WAY behind the DVS

Look up the PTP requirements for the AVIO. You may want to try going direct to the device without a switch, as a test. 

I found that when I used to use virtual soundcard I needed 10ms latency setting on the PC even with 2 channels only to keep things stable.

As far as I am aware, AVIO is only capable of 44.1kHz or 48kHz music transmission. DVS on the PC is limited to 192kHz.

If you are using you own general purpose network, you may be having congestion problems because the Dante network is constantly sending and receiving timing signals even if there is no music being transmitted. SO I recommend changing your Dante "network" traffic over to a VLAN if you can manage it.

If there is no setup software for the AVIO then I don't know what to recommend for it. But check each device's latency by double clicking on a device name in one of your windows you've shown as above and you should get a view like this:

So on my system, I have hardware Dante and clocking (DVS is software only). As long as your actual clocking signals are always less than 50% of your setting, you should be able to discount network issues.

My desired Dante latency is set to 500 microseconds with the software's measured latency from the graph is about average 148 microseconds. 

I will try all the ideas this weekend.  This has great potential even in home audio.  Very Geeky.

@bobfa One of the challenges with DVS for PC audio playback used to be that it did not support dynamic sample rate adjustment-- meaning that it only played at the Dante 'network defined' sample rate. Which would require PC playback apps to do SRC, rather than the DAC. Does DVS support real time sample rate adjustment now?  (for context, link to post in this discussion https://www.head-fi.org/threads/audio-over-ip-rednet-3-16-review-aes67-sets-a-new-standard-for-computer-audio.806827/page-247#post-16286343 )

I do not know

I have Focusrite Rednet D16 AES. Automatic sample rate change is working fine with DVS but this is a proprietary thing, only works with Focusrite devices and only with Windows. I have not heard that SR change would work with other brands for Dante.

My computer is stable with DVS 3ms (1ms works but rises DPC latency) ASIO and 4ms Dante-settings, but I have had problems in DPC problematic systems.

Maybe Ravenna works better? It does have DSD support which Dante lacks.
