Lumin T2 netradio stops

Audio Gear Talk Lumin
1

Starting today, Lumin T2 stops playing some internet radio stations (Bayern2 and BR Klassik) through Roon.
What I mean: Playing will start and after some minute, it stops.
This is not a problem in the network, because on the same switch I’ve some more (five) end points, which are playing without interrupts.
Special thing with these radio stations is, that they have in there playlist three or four streams with mp3 and AAC.
Also I let Roon upsampling to DSD512.

Other content (local files and Qobuz content) is working without problems.

So, what can I do?

2

Please disable Roon DSP Engine and retry the radio stations.

3

That’s I’ve tried also yesterday and then I’d (in two hours running) no interrupt.
But I’ve another end point (Ropieee and an USB DAC) in my home office, where I’m mostly (over ten hours) hearing net radio with Roon upsampling up to DSD512 without interrupts.
So it seems for me, that the Lumin it’s there more sensible.

But it can be also a temporarily issue with Roon infrastructure itself and tomorrow I’ll take care about this in my home office.

4

Please make sure Parallelize Sigma Delta Modulator is enabled if you do any DSD upsampling.

5

Sure, it’s enabled since starting with Roon…

6

Tested yesterday and today again with to end points, for which Roon upsampling net radio to DSD512.
The first is a RPi4 with Ropieee and Topping DAC and the second one the Lumin T2.
The first plays net radio without any interrupt (over 10 hours), but the T2 stops sometimes and there comes a message from Roon, that the address has changed.
Both end points using the same switch and LAN.

7

I’ve never seen this error before. Anyway, if it is what I think it is, please reserve an IP address for the Lumin T2 in the router, then power cycle the T2.

Hello Peter,

thanks for your support, but also setting a fixed IP changed nothing.
And again: Problem occurs only with net radio (not with local files or Qobuz) and resampling to DSD512.
By the way: What has changed in the firmware 14.4c?

9

Just a minor bug fix and some radio station updates.

Please tell me the exact error you saw.

It’s hard to see and find the message (only showing on remote for short time while stopping), but from the logs an example:

I can’t find “address has changed” from here. If it’s impossible to screen capture or take logs, please memorize the exact and complete wording for the “address has changed” message you said you saw and tell me.

Were you playing to a single endpoint (T2) or grouped with others?

Is the network from the Roon Core to T2 and other endpoints completely wired instead of going through WiFi or powerline network?

12

It’s really hard for me, to get the message (only shown a few seconds, while stopping), but I’ll try…

I don’t use groups in Roon and all parts (core and endpoints) are wired.

13

What’s the processing speed in signal path when you’re doing DSD512 upsampling from netradio?

14

1.7x - 1.8x
And again: Only the T2 and here only the net radio is affected.

15

I tried to reproduce your test:

  • Roon 884 on Windows 10 21H1
  • Lumin T2
  • Both connected to a TP-Link SG1008D switch
  • DSD512 upsampling - processing speed 1.5x (slower than yours)
  • Bayern2 AAC for 60 minutes
  • BR Klassik MP3 for 60 minutes

Both played perfectly.

I have sent you experimental firmwares, see if they make any difference.

Hello Peter,

thank you for your test Firmware.
Tried them both, but again the same result.
Now I’ve got a screenshot for it:

Hi,

Thanks for the screenshot.

The only thing I can think of as a next step is to get a cheap switch (Netgear GS105 or any cheap unmanaged TP-Link switch), and have the Roon Core and Lumin connect to this switch. Then connect this switch to the router.

18

Mmmh, switches already changed all to unmanaged one some months ago. The mainswitch is a Netgear GS324 (24 ports) an surely rebooted before testing.
Perhaps I’ve to try change some lan cables.

19

Please try unshielded CAT-6 cable.

20

Sorry for the delay (was in the hospital), but now I’ve changed some things:

  • new core with a Intel Core i9-11900 with 8 cores and boost frequence until 5,20 GHz, 32 GB Ram DDR4, Samsung SSD 970 EVO Plus 500GB on a dedicated system with Ubunutu Server LTS → formally it was installed on a NAS
  • new Roon 1.8 (913)
  • new LAN cables

Now the processing speed with uspamling to DSD512 is 3.1x and I’d no stopps anymore.
Because more things have changed, I can’t say, what the problem has solved.
