Trouble sometimes with 192khz Audio (Tidal/Qobuz)

So there it is to be sure:

I’ve also been having Hi-Res playback stoppages with a Bufferbloat Grade of C. I have installed OpenWrt over the weekend on my Raspberry Pi 4 that now sits between my modem and router. I’m running SQM with Cake and now have no latency - an A+ grade. No stoppages so far, but will continue to test.

[Malte_Weber]

Yes, I think we are looking in the same direction.
I don’t know if rout or internet provider - to be sure lets make clear what I mean if I called it “cable router”:

This coax connection - is my way into the internet:

And from this type of routers - there are only one firm in germany “AVM” with its “fritz box cable” to join the internet. I wait for the next gen router for year to switch - but I still wait.

I’ll try to find a “cable modem” - router combination in future - check this.

I’m thinking it’s something to do with your FRITZ!Box as @noris has already brought up.

I’m running a FRITZ!Box cable router on Vodafone cable and there are no problems with this at all. AVM makes great routers.

It does have a setting to prioritize certain devices on the LAN, as was linked further up. Makes no difference to me but if you have very high LAN traffic it’s worth trying

[Malte_Weber]

By the way - I changed the Fritz Box already; but same model 6690 .

[Suedkiez (Just a fellow user like you)]

My model is the 6690 Cable, for what it’s worth

[Malte_Weber]

I’m just wondering, why all other combinations like streaming via bluesound/mconnect/audirvana… are working fine - I only got probs with roon.

[DrTone (Jeff)]

I assume they implement better buffering and maybe even better error handling.

There is no reason Roon shouldn’t improve the server side pulling from Qobuz and Tidal. The number of users that report issues with Roon only is very very high. Some of these issues are from the overhead of RAAT and the users local network. In your case it’s clearly on the Server to Qobuz which you have proven by reproducing the issue via outputting to HDMI on your nucleus.

Hey @Malte_Weber,

Thanks for sharing the HDMI timestamp! We can confirm that we see network bandwidth allocations dropping to zero, and download speeds below the required threshold for smooth playback of the file.

@Malte_Weber

Regarding the topic qos - I’ll think I have tried everything the router provides:
In both way’s to turn off everything and turn on everything - but I’ll check again regarding the links you provide.

My apologies if this has been glazed over, but perhaps investigating any options to allocate specific network priority to your Nucleus may help here? Fritzbox support may be able to help you with specific steps to do this.
