Dante i/o bug?

[ThatComplicatedMidiGuy]

Hey folks!

On *rare* occasion, with multiple systems/venues now, I’ve booted up a DM48 equipped with M-Dante card and dLive does *not* pass sound through the card. The system appears to see that it’s there, all my routing and tie lines appear to be correct/haven’t been changed, Dante Controller *shows* that connections between the DM48 and other Dante devices are handshaking no problem, but I’m not passing *any* sound on the output side. Dante Primary and secondary both appear online and stable.

To make things more interesting: I have a computer running Dante Via patched *IN* to the DM48 over Dante, (Spotify/iTunes, etc); and those Dante *inputs* to the dm48 seem to be just fine, while output from the DM48 is not. The DM48 Mixrack hasn’t been moved, bumped, jostled, or otherwise harassed, and is fully powered down by way of sequencer between each use. Rebooting the M-Dante card does *not* resolve the issue when it happens. The only thing that seems to fix it is to fully power down, and reboot the DM48. Again, it’s pretty rare that this set of circumstances happens on boot, but its very inconvenient when it does.

Has anyone else experienced this issue? All signs seem to point to this being a software bug in the DM48. I’ll submit a support ticket as well, but curious to know experiences from other users.

…oh, and this has been consistent across multiple firmware revisions. Currently on 1.72, but did see this behavior occur all the way back to 1.68.

I have run into this on a church’s DM48. We had to power cycle the mixrack to restart signal flow to the Dante network. Like you experienced, Dante controller did not show any sync issues.

I’ve experienced this same problem happen 1 time in the last year with our iLive system, complete system reboot got it working again……

Good to know I’m not the only one! I’ve submitted a bug report to AH.

I need a bit more data to forward to Jack though: **If anyone here experiences this bug again,** can you please document what’s you see in TX flow Meters in Dante Controller *while* it’s happening? It’s so rare that this issue occurs, I worry it will be some time before I can get that documented. Thanks in advance!

I’d like to report I also had this issue and another person I know experienced this as well.

The card was inside c2500 in my case.

+1

It helps me change in device dante window in controller latency for example from 1ms to 2ms

When it happens again i change it back from 2ms to 1ms latency.

+1 in 2024 with a DM32 / S3000 / Dante 64v3
First the aux sends died l, then the main outs. After resetting everything imaginable, Mixrack and surface recycle fix it.
Needless to say it was not fun times with client and guests.

I have my first mid-show Dante crash experience as well. Not the M-Dante though, but with 128ch Dante V3 card. It was in AES67 mode receiving audio from a Cymatic player. At some point all the tracks started to sound thin and “metalic” and then the audio disappeared completely. Dante Controller showed that all the packets are arriving late (outside the latency setting value). No other eqipment was involved – just a 128 ch Dante card, the Cymatic player and a MacBook to patch/monitor. Tried to reboot the card itself via DC, no luck. Power cycled whole CDM32, first time no luck. After second power cycle everything was back no normal and haven’t been failing ever since. Still scary a bit.

As for the M-Dante – I have had two major issues witht he M-DL-ADAPT frame, it would stop passing audio at the clock settings change. I had two adaptors and only one did that. Never was a show stopper, because once the clock was set and the complete thing was rebooted it worked just fine. But I have had this happening with two M-Dante cards in the particular convertor frame. The subscriptions were on and no sync/clocking issues reported, just no audio data.
