Is there a specific error message you see? If so, please select from the following options:

· Other

Please try to reboot your Roon Server and check to see if this helps.

· Rebooting my Server had no effect, the issue remains

Please try to reboot and unplug/replug in your affected audio device and check to see if this helps.

· Rebooting and unplugging/replugging my audio device, the issue remains

Please open your Roon Remote and select the "System Output" Zone and try to play to it. Do you encounter any playback errors with this Zone?

· I can play back music *without issue to System Output*, it is only the *other zone that has issues*

What method is the audio device connected with to the server (Roon Ready, HDMI, USB, AirPlay, Chromecast, etc.)?

· HDMI

Is the audio device on the latest firmware version, as per the manufacturer's app?

· Yes

Is there any change in behavior when using a different cable for the connection for the audio device?

· No, using a different cable didn't change anything

Have you reached out to the manufacturer of the audio device regarding this issue yet?

· No, I have not reached out

Does the issue happen with local library music, streaming service music, or both?

· Only local content affected, and I don't have any streaming services to test with

Where is your local content stored?

· Somewhere else on the local network (NAS)

If you move the content from your NAS to a local storage location, do you still experience issues with playback?

· The issue happens for both the NAS storage location and on the secondary storage location

Please try playing content of a lower sample rate (44.1kHz or 48kHz), does this work as expected?

· The issue only impacts higher sample rates

What is the model/manufacturer of the affected audio device(s) and the connection type?

· Marantz AV8805, Intel NUC6i56YH Roon Bridge

Describe the issue

I have a problem with DSD multichannel content from a Intel NUC windows 10 machine with Roon Bridge to a Marantz AV8805. Music will not be played („Failed to initialize the audio device“). This does not happen if I use Roon ROCK (ALSA) as an endpoint. The problem occurs only if I use exclusive mode with max possible bitrate 192 kHz/24 bit. If I do not use exclusive mode the files will be played with 176,4/24 as expected. If I lower the max rate in device settings to 96 kHz music will be played with 88,2 Khz. So,what is the problem here? Why I cannot play my DSD multichannel files converted to 176,4/24 like under Linux? DSD stereo with only two channles is not affected. Win 10 is up to date with newest drivers. A cable change helped not.

Describe your network setup

Connected to a stable LAN

I found the same issue by @Richard_Patton in this thread:

DSD failed to initialize audio device [Investigating]

I am all of a sudden seeing this exact same behavior on multiple systems. They all used to work just fine. When I try to play DSD (DSF format) multichannel from Windows PC (both Win 10 & Win 11) I get the error “Failed to initialize the audio device”. I have this problem on with a Win 10 DIY machine connected via HDMI to a Yamaha A1030 receiver and on a Dell Optiplex with Win 11 connected via HDMI to an Anthem Statement D2V pre-pro. Both these machined worked fine earlier in the year. Multichan…

Hey @Enno14,

Thanks for writing in! Sorry to hear about your playback issues. Could you next please reproduce the issue and share a more specific date, time, and name of track played?

Our team will take a closer look from there

Hi @benjamin,

I tried to play several dsd multichannel tracks about 5 minutes ago with „Failed…“

Does it help?

Thanks @Enno14, our team will take a closer look!

@benjamin

Is there any progress? Do you need some more informations?

[benjamin]

Hi @Enno14,

No progress yet, we have a ticket in the queue with our development team, but I’m not able to speak on any timelines, unfortunately.

When I have more information to share, you’ll be notified!

[benjamin]

Hi @Enno14,

For our dev team, could you please share a specific step-by-step reproduction of the multichannel failure? This will eliminate any potential variables in our steps to reproduce the issue in-house.

Thank you!

Hi @benjamin

It is quite simple. Try to play a DSD multichannel track with a WIN 10 Intel NUC in WASAPI Exclusive mode. It does not work.

Everything else is written already by @Richard_Patton and me.
