First Song on some MQA Albums is not Streamed via UPnP

I am currently using a MacBook Pro (late 2013) that is hard-wired to the ethernet. Music is supposed to be streamed to my Hegel H120 which does not support MQA decoding. Actually the set-up works fine. However, the first song of some MQA albums is not played. I have to restart Audirvana in order get it back workin. For example, “Bruckner: Symphonies No. 4 - No. 9 (Berliner Philharmoniker, Herbert von Karajan)” has this issue. For some reason the first song is not played…

Any ideas to solve this issue are highly appreciated…


The Hegel has the newest firmware installed.

This is what it looks like when playing Track #2

…this when switching from #2 to #1. 24/192kHz is not correct…

Same here…

Track #3 from this album works perfectly…

BTW, the first track is played when the MacBook is connected to the Hegel via USB…

If you try with local flac tracks, do you have the same issue?

Yes, I do. This issue is only associated with MQA tracks but not with all of them. The tracks that are not played with Audirvana are played via mconnect (i.e. without MQA unfolding). If I change the settings in Audirvana to “MQA decoder” (i.e. leave the decoding to the Hegel) the tracks under discussion are played. So the issue seems to be impacted by the MQA unfolding done by Audirvana…
I re-installed the software but the issue persists. Are there any caches I might try to empty or system files I may want to try to delete…?

Are you using the latest firmware from Hegel?

Yes, I do - just verified…

Have you tried to reset the network settings of your Hegel?

Thanks… I just reset the Hegel to factory settings but it did not solve the issue.

Can you try using Airplay?

There is a regression not fixed by Apple since OS X 10.11 (El Capitan) that makes the AirPlay device unavailable to any application other than iTunes (it is not even listed in Audio Midi Setup application). Until Apple fixes this, there is a workaround to get it back:

  1. Option/alt click on the loudspeaker icon on the menu bar

  2. Select AirPlay in the selection menu that appears

  3. You can then select AirPlay in Audirvana Audio Device Settings.

If the loudspeaker icon is not displayed on the menu bar, you can show it by going to System Preferences, Sounds page, and set the “Show loudness in menu bar” option.

In addition, be sure iTunes is not set to use the Airplay device.

Maybe I do not get the point but AirPlay is not the issue here. If I would use AirPlay I would not be able to take advantage of MQA since streaming would only be at 16/44,1 (the Hegel does not support AirPlay 2 yet).

This is just for testing purpose and find what is the source of the issue. Can you try with Airplay?

I see. Airplay works…

Your Tidal account is not connected anymore in Audirvana, can you try with a track from Tidal?

This is correct. I do have this album also on my NAS. TIDAL is also working with AirPlay. This Bruckner recording (first track) did not work via UPnP…

Do you have another app that control your H120 at the same time as Audirvana is opened? Audirvana do not send audio over UPnP in flac, it send it in wav to not loose audio quality of your track.

No, mconnect is always switched off on my iPhone. Interestingly the issue impacts only the first song of some MQA albums. Moreover, if Audirvana is set to “MQA decoding”, i.e. if the unfolded file is sent to the Hegel it is working…

When you have MQA Decoding enable, can you open the debug info and check this line:


Do you see mqa in the link?
