Describe the issue

I was not able to enter correct answers above because my situation is not covered. I have an Aqua LinQ streamer with an HQPlayer module. I have a new DAC so he connection is now with single AES which does not allow play above 192 so such albums would not play. I had to reduce the level of resolution. I cannot do that for owned albums on Roon or with the LinQ but only with HQPlayer. I did that and they played at the lower resolution. However, later when I tried to play the same album again it would not play. Nor would anything else. I cannot use the LinQ at all
I tried redoing the HQPlayer selection in Roon. However, that didn't help. I feel I am doing something wrong. I checked the router. HQPlayer on the LinQ is in two modules. I am supposed to register "Core" in HQPlayer set-up on Roon then play with the other module. I find that only one module has an IP address on the router (Starlink). I rebooted and it switched to the other. I tried entering the non-Core module IP as another option but that didn't work either.
I have no comprehension of networking. Help is much appreciated.

Hello @Susan_Tyler

Welcome to the community! High-end audio setups with streamers, separate DACs, and HQPlayer are incredibly complex, and throwing a Starlink router into the mix adds another layer of unpredictability. We will take this one step at a time.

I took a look at the “under the hood” diagnostics from your Roon Server, and your instincts were spot on. There are two distinct things happening here, causing the music to stop: the Starlink router is confusing the IP addresses, and the 192kHz limit of your new AES cable is causing a crash. Would you kindly clarify how each endpoint is connected to the router, wiredly or wirelessly?

Here is how we can fix both, step-by-step:

You mentioned noticing that the IP addresses for the modules seem to switch when you reboot. The logs confirm this: Roon is frantically trying to connect to HQPlayer on 192.168.1.82, and then suddenly it tries 192.168.1.28, fails, and gives up.

• The Fix: If the Aqua LinQ has multiple connections (WiFi and Ethernet), ensure you only have one Ethernet cable connected to it, running directly to your Chord switch.

2. Solving the 192kHz Limit using Roon’s MUSE

Instead of trying to program HQPlayer to limit the resolution, the easiest and most reliable method is to let Roon handle it before the music even leaves your Nucleus.

Roon has a built-in DSP (Digital Signal Processing) engine called MUSE that can automatically step down those ultra-high-resolution tracks to 192kHz so your AES cable can handle them without crashing.

How to set it up:

1. In Roon, click the Speaker icon (your Zone) in the bottom right corner.
2. Click the MUSE icon (it looks like a squiggly).
3. Click on Sample rate conversion and toggle the switch to Enabled.
4. Change the dropdown menu at the top to Custom.
5. You will see a list of all possible sample rates (44.1kHz, 48kHz… all the way up to DSD512).
6. For any rate above 192kHz (like 352.8kHz, 384kHz, and the DSD options), click the dropdown next to it and change it from Default to 192kHz (or 176.4kHz for the multiples of 44.1).

Once this is set, Roon will automatically “translate” those massive files into a size your DAC and AES cable can happily play, preventing HQPlayer from crashing.

Were you able to find that MUSE menu and adjust the higher sample rates?

[Susan_Tyler]

Thank you very much for your help. The LinQ has one ethernet connection, to the switch. The Rossini has one ethernet connection to the switch. I made the adjustments in Muse. However, I received the same message when I played a file that is in 96 in my library at just before 7:15, or a few minutes ago. I tried streaming just now at 17:17 and also failed. I think I need to do something to the settings in the LinQ. Can I restore the HQPlayer settings to the defaults? The dealer set them for us so I am not sure what he did but it is likely to be obvious, and I can look around and see what I can do. I really can’t see how the system can work if I am trying to play with the renderer with IP ending in 1.28 but have set HQPlayer in Roon to the Core with IP ending in 1.82

[Susan_Tyler]

I reset the HQPlayer Core to Factory Defaults and have music. Please don’t close the ticket yet since this might not last.

Thanks for the help

Hi Vadim,

When I started playing music I discovered that one of my SSDs has disappeared and many albums in the one that is there are now duplicate. I have not done anything except set the Muse settings as you suggested. They have gone back to what they were, by themselves.

[Susan_Tyler]

Hi Vadim,

Roon is back to normal! Well, sort of. The other storage disc reappeared, but the duplicates and also triplicates are still there. Perhaps not quite as many albums altogether are involved?

I guess this is a different issue altogether

[benjamin]

Hi @Susan_Tyler,

Thanks for the follow-up! I’m not seeing any prior mentions of duplicate content, so if you could please provide a bit more detail around what you’re seeing, including specific examples, that would help.

If you could also please share a screenshot of your Roon Settings > Storage, that would be helpful as well.

And lastly, I’d double-check that you have ‘show hidden tracks and albums’ disabled under your Roon Settings>General.

Thank you!

[Susan_Tyler]

Hi Benjamin. I was possibly responding to the wrong place.

At present in artist view all albums are duplicated.

[noris]

Hello @Susan_Tyler ,

Thanks for the screenshot. It looks like you have both For roon 2 and For Roon folders selected, do you by any chance, have actual duplicate content in both folders? Is there any change in behavior if you try to update Roon to the latest version and perform a full reboot of the device?

[Susan_Tyler]

Thanks, but I have seen up to seven duplicates. There is no duplication in the drives. I’ve been through the library checking for duplicates with focus and it is not a problem. I’ve done a power cycle. I’m up to date with Roon software up to now. At the moment it has settled down, but I haven’t done anything to fix it. Last failure was April 26. I’ll write again when it does it again

[Suedkiez (Just a fellow user like you)]

If you select one of the duplicated albums, do all of the duplicates get selected by any chance?

[Susan_Tyler]

Haven’t tried that. I will when it happens again, hasn’t in several days.

[Suedkiez (Just a fellow user like you)]

I’m asking because there was or is a known issue where albums (sometimes artists too) become visually duplicated, i.e. the object exists only once but is displayed several times. It’s fixed for a while after a reboot.

[Susan_Tyler]

Thank you. I think I didn’t want to worry about which one is real since all are only images of something real… I’ve been over the library for duplicates and there is only one album in the library, for a reason, and “hidden”. I have rebooted a number of times and done an overnight rest of the whole system. The duplication is associated with Roon dropping out I think, but not always. I’ll try to keep better track. Maybe it won’t happen again
