I’m running B1605 on my rock server.
The behaviour that I’m seeing is that:
I press play to listen on my lumin U2 Zone.
It indicates - connecting to the Qobuz source, - FLAC file etc.
No sound comes out, and there’s no progress on the player bar.
It stops. Source connection disappears. Nothing plays.
I try a radio station. Same behaviour and nothing plays.
I change the zone to my local computer and press play. It works. It plays music both from Qobuz and Radio.
I change the zone back to lumin U2 Zone, and I get the same behaviour as 1-5 above.
To resolve the problem.
I either restart the Roon server. Then, it plays fine from the Lumin U2 Zone, without any issues, both Qobuz and Radio.
OR:
I play music on my local computer and as it’s playing, I transfer the music zone to the U2 Zone, and it works then. The music transfers and it plays fine from there. Radio works fine. Qobuz works fine, local library works fine.
Power cycle the whole network of devices starting from the router, WiFi mesh, access points, network switches, Roon Server, Lumin, NAS, phones, tablets, computer(s), etc.
After Lumin is powered up and shows a progress circle on the front panel, power cycle the DAC, switch to correct input and connect it to Lumin.
I’ll give that a go tomorrow. In the interim, I’ll expand on the post to say that playing music via Lumin app, Airplay, Qobuz Connect, and Spotify Connect connecting to the Lumin U2 still played music fine. It’s just Roon that’s acting up. Things were working fine till B1600, and I thought it was the Zone dropping issue that was reported by another user. But, now, after a bit more testing with B1605 - I narrowed down the problem & how to resolve it, but it doesn’t make sense to me. I’ll do the power cycle exercise tomorrow and report back.
I’ve restarted everything as you’ve suggested, and yes, it worked. But the next day Saturday, and the next day Sunday, and the next day Monday. I have had to resolve the issue with:
I play music on my local computer and as it’s playing, I transfer the music zone to the U2 Zone, and it works then. The music transfers and it plays fine from there. Radio works fine. Qobuz works fine, local library works fine.
I’m not bothering with restarting the Roon server. For me, it’s an issue with the early release builds that came out B1600, and now B1605. I’ll wait to see what the upcoming 2 to 3 builds bring, or just switch it to the production server.
I think it could be that Roon doesn’t like that I’m powering off the U2 and Amp from its’ interface, and then the next day starting them up. I’ve just enabled Auto-turn off from Roon, so that I don’t turn them off myself - just to see if it manages to turn them off and then I start them up, would it then play nice with things or not.
I’m able to play directly to the lumin using Airplay, qobuz connect, spotify connect, and the lumin app, without a problem everyday. It’s just Roon that’s being silly.
Hi, @Tigo, thank you for you post. Could you please tell me if the pattern I described below is correct:
You have a Lumin U2 network zone
It works after RoonServer reboot
However, after you turn Lumin U2 off via its interface and then turn it on, when you try to play anything via this zone using Roon, no sound comes and after some time you get and error message and then the source track disappears from the footer in Roon
If that’s correct, can you please not the timestamp next time it happens and let me know? I will request a diagnostics report from your machine and will pass it to our dev team.
I can narrow things down a bit further as I did a couple of tests.
The U2 zone has an MA9500 connected via USB to it.
U2 network zone, connected to an MA9500.
Yes, it works after a reboot of RoonServer.
However, after I turn the Lumin U2 off via Roon interface and turn off the MA9500. Then turn first the MA9500 on, let it settle (gap is necessary so that Roon identifies full capabilities of Lumin zone), then turn on the U2 and try to play anything via this zone using Roon, no sound comes and after a couple of seconds the source track disappears from the footer in Roon. No error message is generated.
Another scenario that I just identified.
I’m listening to music at the U2 zone.
I turn off the U2 streamer alone. Leave the amp on. (this was a short period under 5 mins to see if it works).
Turn the streamer back on, and Roon will play music.
Timestamps: 3rd-Feb. 0755 AEST - 0810, and then 0830-0845 AEST.
In the configuration for the U2 in Roon - I disabled the Enable MQA Core Decoder option within it. Now, everything is working again. I had that option enabled as I was subscribed to Tidal initially for a couple of years before moving to Qobuz, it’s not needed at all now.
Correction to my earlier comment. After a bit more testing - on / off - (i.e., coming in to use the system). It wasn’t disabling the Enable MQA Core Decoder that resolved the playback issue. It was initiating some control change on the zone that then led Roon to go ahead with transmitting to that zone.
Yesterday evening, I had both the amp & lumin off. I turned on the amp, then turn on lumin, - pressed play to listen to music. No sound came out. I made the change of disabling Enable MQA, and then music started playing.
Today after starting up the amp, then lumin, then pressing play, - no sound came out, and the same issue occured. So, then I enabled the MQA core decoder, and, it started working - playing music.
So, I guess another approach to resolving the issue would be to just make a change to the zone as opposed to transferring music from one zone to another.
