Sometimes Error if plays long in RadioMode

Support Nucleus Support
1

Hello there,

when RoonRadio is playing for a longer period of time(which i like a lot!), it sometimes just stops or even the USB connection to the DAC is not ressurectable. Then i have to reboot my nucleus and plug the usb dac cable to the other usb port in the nucleus.

Maybe you can seen on the Logfile whats going on when this appears…

Hardware:
Roon Nucleus+
Direct USB Connection from Nucleus to the DAC (Accuphase DC-37)

Here are logfile-snippets of what happens after a longer period of time playing in RoonRadio-Mode:
I had to delete the lines containing hyperlinks to be able to post that logfile fragments.

Kind regards
Chris

Hi @Chris0,

Does this only happen when you’re playing to the Accuphase DAC? If you play to a different endpoint (even system output of a remote) does the same behavior occur?

Can you share a screenshot of Device Setup and the Signal Path when playing to this device?

Thanks!

Hello Dylan,

“Does this only happen when you’re playing to the Accuphase DAC? If you play to a different endpoint (even system output of a remote) does the same behavior occur?”

I never used roon in this way before.

Screenshot:
the signalpath is as described in the logfile above…:

–[ SignalPath ]---------------------------------------------
SignalPath Quality = Lossless
Elements:
Source Format=Flac 44100/16/2 Quality=Lossless
Raat Device=Accuphase USB Audio Product2
Output OutputType=Local_Alsa Quality=Lossless SubType= Model=Accuphase USB Audio Product2

or as screenshot, which contains the same information:roonscrnsht

Actually it seems that this happens sometimes when roonradio picks sometimes an MQA file from tidal and roon decodes this for the dac preperation… Is it possible to exclude tidal for roonradio and only use qobuz? I use both tidal and qobuz…It is also worth to tell that this never happens with local content (flac up to 192/24 and some dsd 64 and 128).

And here the setup:

I think Dylan means, can you please try and use a different endpoint to see what happens. If it works elsewhere then it might be something in the accuphase set up.

6

It is the usb interface in the nucleus that crashes, not the dac…

And… I sadly dont have another endppoint…

7

You use a device to control the system, play to that.

8

Ah, yes, my old iPad Air. I didn’t realised that this is also an endpoint…
Thank you.

I will wait for dylans reply. Ofcourse i test all they want, if i can. But this would change also the nucleus output driver/interface that is used for the usb output - and this is crashing.

9

I think the point is that they want to know exactly what the problem is. So to narrow down the possibilities if you test, as they suggested, on a different endpoint and it crashes then that tells them things, it also tells them things if it doesn’t.

10

Yes… I let this run now over my iPad…
Usually it takes a day or two until this happens(with the Accuphase setup)
I am curious if this also happening on my iPad…

Hi dylan,

it stops also with my ipad as an endpoint. It looks not like the same reason as with the accuphase, but it stops.

I switched back to my accuphase. I disabled the mqa decoder and start again with my accuphase.

By the way, why roon dont offer native dsd to my dac?it only offers dop and origindcs. But the DC-37 can handle up to dsd 128.

Kind regards
Chris

Hi @Chris0,

Not all DACs support native DSD linux drivers, native DSD support has to be patched into the kernel.

Can you clarify what occurs on the iPad? Do you also have stoppages there with Roon Radio? When the Accuphase is in this state where playback cannot be started, does the iPad still work as expected?

13

Hello noris,

Can you clarify what occurs on the iPad?

It stops playing after hours of playing in RoonRadio mode.

Do you also have stoppages there with Roon Radio?

Only with RoonRadio - not also.

When the Accuphase is in this state where playback cannot be started, does the iPad still work as expected?

Yes, on the iPad everthing is fine. There are no harmfull exceptions in the logfile like with the accuphase. With the ipad there are just a lot index out of bounds entries and sometimes connection refused to the iPad.

kind regards
Chris

Hi @Chris0,

Can you please post the snippet from your log showing this error?

Since the issue occurs on both iPad and the Accuphase, this might be a networking-related issue. Could you also provide some information regarding your network setup such as model/manufacturer of your router/switches/ect.?

Do you have the default ISP DNS servers or have you configured custom DNS on your router (such as Google / Cloudflare / Quad9)?

15

Hello Noris.

My nucleus is hardwired to the router. Using DHCP.

And…:
I wrote: It is not the same issue as with the accuphase…

Here are that logentries with the ipad as endpoint… Harmless as i told you. I am not surprised, the ipad is ofcourse wifi connected…

And now compare that to the dead usb interface showed in the logfiles in this initial post…

And last but not least:

When the Accuphase is in this state where playback cannot be started, does the iPad still work as expected?
The Accuphase cant restart because of the dead usb interface…

You guys didnt even look into the top logfiles, or?

Kind regards

Hello @Chris0,

The Nucleus communicates with connected USB DACs using the standard Linux ALSA driver set.

Looking at the logs, it appears that the Accuphase USB chipset is becoming unresponsive when the driver is attempting to have it switch from 24/88.2 playback to 16/44.1.

Trace: [RAAT::Accuphase USB Audio Product2] [ALSA] [hw:CARD=Product2,DEV=0] using hw pcmformat S32_LE bitspersample 24
Trace: [RAAT::Accuphase USB Audio Product2] [ALSA] [hw:CARD=Product2,DEV=0] Requesting 2 periods
Trace: [RAAT::Accuphase USB Audio Product2] [ALSA] [hw:CARD=Product2,DEV=0] Requesting 3528 frames/buffer (1764 frames/period)
Trace: [RAAT::Accuphase USB Audio Product2] [ALSA] [hw:CARD=Product2,DEV=0] Initialized with 2 periods with 1764 frames/period and 3528 frames/buffer
Error: [RAAT::Accuphase USB Audio Product2] error in snd_pcm_hw_params: Input/output error (-5)

Since Roon is using ALSA as the medium between itself and the DAC, it is likely that this issue is due to an incompatibility between the Accuphase USB chipset and ALSA.

As a test, could you enable the “Headroom management” feature in Roon and attempt to play Roon Radio for an extended period of time? Headroom management will result in a consistent 24bit or 32bit stream to your DAC (Roon performs 64bit DSP and then dithers to the highest bit-depth your DAC supports) preventing the 24->16 switch. This would help isolate what the cause of the issue is.

Hello John,

i agree with your thesis. The issue is very likely between the USB Chipset and ALSA. I also think it increases the chance of fail when switching the bitdepth. All in all it is strange that this happens rare and is not solid reproduceable, which doesn’t agree with a real “incompatibility”. Most of the time it works…

With completely excluding MQA the roonradio runs over the last days without any fail. But this is maybe only, because the amount of bitdepth changing per time are reduced enough caused by excluding MQA. - or it’s just random…

I follow your advice and enable the headroom to ensure allways the same bitdepth. Which also reduces the number of switches. Now only the divider switch is left, but that is hopefully not involved.
I also re-enable the MQA-Decoder of roon.

By the way: This is the USB Chip:

USB-Chip-Accuphase-DC-37

I will report what happens in the next days…

Kind regards
Chris

PS: In what timecycle the logfiles get deleted? Until now i did this manually…

PSPS: I dont know why some textparts are sometimes bold… Sorry for that…

18

Hello @Chris0,

Appreciate the details about your testing! My experience is that there is often a “race condition” in cases like this where it may fail or not fail based on the timing of the commands. The bit-depth change is the most common culprit for this.

PS: In what timecycle the logfiles get deleted? Until now i did this manually…

Each time Roon is restarted it will open a new log file. When the per-log max of 66k lines is reached, Roon will then open a new file and increment the old filename by one.

The Roon database stores up to 20 log files and will automatically delete the oldest files as new log files are generated.

-John

19

Hello John,

back for report. It plays still without errors with the bitdepth upscale made by the headroom management. So it seems to be really between the USB-Chip and ALSA.
Do you think there is a realistic chance that this will be fixed? Would be nice not to be forced to manipulate volume(headroom) just to avoid that issue.

Kind regards
Chris

20

Hello @Chris0,

Considering the issue is related to the USB chipset, I imagine any fix would be difficult to implement. We have little to no diagnostic information on our end—all we know is that the USB chipset is failing to respond when ALSA requests the bit-depth change. Accuphase would be best positioned to determine the cause of the issue—they are not a Roon Tested partner so we do not have their hardware to test with.

-John

21

Hello @john,

thanks for the answere.

Hmm, i see there the problem in the bitmask that ALSA has in it’s command to the chip. It is rarelly just invalid. And the chipset ist not failing to respond, but the whole USB Port is crashed on the nucleus side.
Ofcourse i have no glassball, but from the technical side it looks a lot like a prob inside ALSA.

But… The real problem is, that Accuphase is no roonpartner. And i further expect there would be no reaction on there side (help exemining) this problem.

Kind regards
Chris
