Playback stops and Wandla DAC disappears from connected audio zones (ref#H286M1)

[Ryan_Quadrel]

What best describes your playback issue?

· My DAC, streamer, or speaker doesn't appear as a Zone in Roon

What type of Zone is affected by this problem?

· *Directly-connected Zones* are affected.

Is your device connected directly to the Roon Server via cable or over the network, or is it chained through another device (such as a streamer, Roon Bridge, or Roon Remote)?

· Connected directly to my RoonServer machine

Does the device show up at all in Roon Settings -> Audio?

· No, it does not show up there

Does the device play audio from another source when using the same connection?

· The device has no problems with another audio source

Have you checked that Roon is whitelisted in any firewalls?

· I've checked the firewall and the issue remains

Since you are using a network connection to the device, please ensure that your RoonServer is on the same subnet as the device

· My devices are on a single subnet but is not visible to Roon

Do you have a complex network setup?

· Both the device and RoonServer are connecting to a *single router*

Try to disable any additional networking interfaces on your RoonServer machine.

· Disabling network interfaces had no change in behavior

Check to make sure RoonReady mode is selected on the device.

· I've checked this and the issue remains

If the device has multiple output options, do the other options work as expected?

· Only one output type is affected while the other output type works as expected

Is the device using the latest firmware as per the manufacturer?

· Firmware is up-to-date but the issue remains

Do you have an approximate timestamp of when the issue last occurred?

· Hanz Zimmer Pirates of the Caribbean

What are the make and model of the affected audio device(s) and the connection type?

· Ferrum Wandla by USB-C

Hi @Ryan_Quadrel,

Thanks for writing in and sharing your report!

We were able to review your account information, and see two instances of Roon Server tied to your account - one on a ROCK, and one tied to your Mac also running Roon as a remote. Do you see this issue on both instances of Roon Server, or only when you’re using your Mac as both a server and remote?

We were able to review a recent diagnostic report from your ROCK and observed the following failures around the timestamp you’ve provided:

Warn: [Wandla] [zoneplayer/raat] Too many dropouts (>3s dropped out in the last 30s). Killing stream
Trace: [Wandla] [zoneplayer/raat] too many dropouts. stopping stream

With that, we can see the buffer is at 100% right before the issue occurs: Trace: [Wandla] [Lossless, 24/48 QOBUZ FLAC => 24/48] [100% buf]

So it appears the network / playback issue isn’t between your ROCK/ Roon server and upstream services like Qobuz, but rather, the network bandwidth within your local network, between your devices.

Can you get a temporary hardwire connection between your endpoint and server devices - directly to your primary router, and see if the same issues occur?

Thank you!
