Description of Issue

The issue related to not being able to use the dac connected directly via USB port was said to be solved by disabling MQA USB HID. I don´t see this option on any settings parameters

I don´t see this option on any settings parameters

I don’t have this DAC but based on this post, …

Cambridge Audio CXN no longer working on USB

Hello @Geoff_Bulte, In the “Device Setup” screen for the Cambridge CXN, can you try turning on the “Disable MQA USB HID Protocol” option and see if the behavior changes at all? -John

… I suppose it should be here:

and then

[Mercio_Moreira]

Thank you. I tried this path, yet, no option with such a name appears:

Well, this seemed reasonably answerable to be, but now I’m lost. I guess we need someone with the DAC after all

A thought: Is MQA support enabled in the main section further up?

FWIW, I read the other thread. @mjazz wrote that this didn’t help:

Skipping w/o playing Music on ROCK with DAC directly attached to it

Hi John I have disabled the MQA USB HID protocol and it does not make a difference. The issue is still there. To be sure, I deleted the RAATServer directory as well, but that did not help either. Thanks Menno

But then this was the solution:

Skipping w/o playing Music on ROCK with DAC directly attached to it

Hi John I now switched again to USB 1.0, which didn’t help. After switching back to USB 2.0, I thought I try it a last time for today. And it works. No clue, why. Perhaps the USB switch on the Arcam? Which I never used before. Anyhow the problem seems to be solved. Thank you for your help A happy roon user! Menno

I am just guessing as you are surely aware

[Mercio_Moreira]

Good point.

Indeed it was not, as it does not support MQA. Yet, after ou comment, I tried enabling to see if I could get this field to appear, but the given “MQA HID USB” option still does not show.

I understood from other posts the support team needs to parameterize your account someway so that this option starts being visible for the user. I am hoping someone from dev team could confirm and to that for me. I am about to give up Roon. I bought a NUC only for running Rock, but it has been so difficult so far.

Pity.

Yes, I wondered about this as well due to this:

Hello @mjazz, I have enabled a diagnostic function on your account that requires a restart of your core to function correctly. After restarting your core, go to the “Device Setup” screen for your ARCAM DAC, click the “Show Advanced” button, and set the “Disable MQA USB HID Protocol” option to “Yes”. Let us know if this changes the behavior you are seeing! -John

But it seems to me that this was only to enable the diagnostics. Who knows though. I guess you might have to wait for Support to show up, which may take several days though

[Mercio_Moreira]

Yes, I got this part. Thanks for enlightening.
I tired USB 2.0 since the beginning. The only part I could not do so far was this MQA HID USB thing. At first I thought it was something like setting MQA to “not supported” as it already was set. Yet, reading again I realized it may be something else. My last drop of hope.

[Suedkiez (Just a fellow user like you)]

I am often quite good at stabbing in the dark, but not so much this time I’m sure someone else or eventually support will be able to help. Good luck!

[Mercio_Moreira]

Hi.

I also tried switching back and forth. Yet, with no positive results.
About the firmware, I also have the latest version.

[Mercio_Moreira]

I am trying Rock.
With Windows it works fine, even without any special driver.

[Mercio_Moreira]

Can anyone from #support give some help?

Hey @Mercio_Moreira,

It’s great to see you on the Roon Community! You have my sincerest apologies for the delayed response here, we’ve been dealing with a higher-than-usual volume following our release and we’re working as quickly as we can to get back to everyone.

For next steps, we’ll need you to refresh your RAATServer database. Please make sure Roon is not running on ROCK or your Windows remote during this process:

You can generate a new RAATServer instance on your device by following these instructions, but please be aware that this will reset your Roon Settings → Audio Tab to factory settings and I would advise making a backup of any custom DSP settings you have:

• Create a Backup of your current Roon database
• Exit out of Roon
• Navigate to your Roon’s Database Location
• Find the folder that says “RAATServer”
• Rename the “RAATServer” folder to “RAATServer_old”
• Restart the Roon App to generate a new RAATServer folder

After you’ve completed this, you’ll need to delete the endpoint_* files from your core database. You can find these files in your file path: Roon\Database\Registry\Core

Once done, you should be all set to go

[Mercio_Moreira]

I did all this before starting this post.

What I imagine is that Rock is not able to work with my DAC.
I installed Roon over Windows and moved on with life.
I would love this compatibility with Rock to exist somewhere in time.

Regards.
