Roon Disconnects from HQPlayer

Audio Gear Talk HQ Player
1

I’ve checked various forums and threads but haven’t discovered a solution; If i missed something my apologies.

My setup is as follows: Roon NUC Server → HQPlayer (dedicated PC)–>Holo Red–>Holo May DAC.

All connections are via ethernet through my Unifi gigabit switch.

HQPlayer Desktop 5.10.1 is running on a newly built dedicated PC; AMD 9950X, 64 GB RAM, Cuda offloading to Nvidia 4070 Ti Super.

Recently I am getting random disconnects; music just stops, and Roon states that it has lost control of the audio device. I have disabled Windows firewall, ensured that Windows 11 network setting is set to Private Network, made sure there were no ethernet sleep settings enabled, adjusted the ReSync Delay on Roon to 500ms, but the issue still occurs.

Digging into logs, the following is reported in the Roon.log

Roon seems to lose connection with the endpoint.

Any advice on how to resolve this issue would be appreciated. I have tried switching to wifi, ensured that the explicit IP for HQPlayer is set in Roon, restarted every service multiple times.

BTW, Roon–>Holo Red as a streamer end point never loses connection. This only occurs when HQPlayer is in the path.
Thank you.

Please check that you don’t have anything related to your DAC or Holo Red enabled in Roon Settings / Audio.

For this case, I’d recommend to just write NAA OS on a spare microSD and boot up the Red from it. It also prevents above issues.

3

Thanks Jussi. Can you advise or direct me to documentation on how to load the NAA OS for Holo Red? Does this replace my Holo Red OS and the ability to connect directly to my Dac from Red? Thanks.

You need a spare microSD card (4 GB or larger) and you can download a 7-Zip archive from my website (see under Network Audio Daemon and “images” subdirectory). Then extract the .img file from the 7-Zip archive. You can then use Rufus (on Windows) or balenaEtcher (cross platform) to write it to a microSD card.

Then you power down Red, swap the microSD and power it up again and you are done.

Yes…

What do you mean by this?

What I meant is currently the Red OS allows me to use it both as a Roon end point and as a NAA endpoint. So if I wanted to just bypass HQPlayer, I can select the Red in Roon instead of HQP. I’m assuming that with this new OS, the Red will only act as a NAA endpoint and if I wanted to use the red as a streamer, I would have to power down, switch back to the Red OS?

6

Now, the important part is that you must disable this output from Roon Settings / Audio if you are using HQPlayer. You cannot have both enabled at the same time… Please see the last bullet point on this page:

This is constantly the most typical problem people are hitting…

So generally, you wouldn’t be switching between the two. You would always use HQPlayer, or always Roon. IOW, if you have HQPlayer, why wouldn’t you use it always?

7

The Holo Red is not enabled at all in Roon; simply HQPlayer.

My use case for not using HQP would be if I wanted to just use the NOS goodness of the May Dac, and if I didn’t want to power on my PC which is hosting HQP. Mainly the ease of use to toggle between OS and NOS.

8

@jussi_laako it seems to be working with the HoloRed NAA OS loaded onto a new microsd card. I’ll keep it running all night and report back.

If it does work, can you explain what optimizations this OS has relative to the Red OS shipped with the Holo Red that has built-in NAA support?

Also, should I set a static IP for my desktop, on which HQPlayer is running, since I have the HQPlayer specified by IP through ROON, and I’m worried that may change? Can I use the DNS name instead of IP in Roon?

Thanks much.

@jussi_laako just to report back that your NAA OS worked without any playback pause for over 12 hours now. This is great. Can you provide a high level explanation of what is different about your NAA OS implementation from that bundled with the Red OS? Will this have any effect on jitter or sound quality out of the red into my dac? Thanks much.

It is just custom built to work best for this single purpose.

Red OS is more general for various different streaming systems, and has functionality to switch the network streaming system when it detects activity on another one, this may also cause accidental disruption on the NAA.

Yes, it is safest to use a static IP, as dynamic IPs are of course subject to change. I believe DNS name should also work, at least what I recall using.
