Core Machine (Operating system/System info/Roon build number)
Desktop PC with Windows 10 (64 bit) and Roon Version 1.7 (build 571) installed.
Network Details (Including networking gear model/manufacturer and if on WiFi/Ethernet)
Desktop PC and Hegel H390 are both connected via ethernet cables to a Fritzbox 7490.
Audio Devices (Specify what device you’re using and its connection type - USB/HDMI/etc.)
I control the Roon core with the Android Roon app installed on my mobile. As long as we are all waiting for the Roon update for the Hegel H390 I am forced to use Airplay to play music on the Hegel H390 with its internal DAC/Streamer.
Description Of Issue
I have noticed some odd behavior with my Hegel H390 amp regarding volume control. I use Roon via Airplay and I have noticed that the volume shown in the Android Roon app is different compared to the volume on the H390 - not much, but it is always a bit off by 2 db or so. When I change the volume on the H390, the volume in Roon changes as well so both the H390 and Roon do communicate in some way. However, when I change the volume in Roon, it sometimes takes volume changes of 5 db or more before the H390 even reacts.
I can live with that as I usually use the RC8 remote of the H390 to control volume. However, a very annoying thing only occurring very recently is that the volume of the H390 changes at its own will. When I use the RC8 to change volume to e.g. 35, it changes back to 37 pretty much immediately. This happens over and over again. When I change the volume to 33, it stays at 33, but when a new track begins to play, it often changes back volume to 37 again. This behavior can be reproduced at certain other volume levels as well.
I cannot tell whether this behavior is connected to Roon, to the latest firmware release of the H390 or to Airplay in general. I already contacted the Hegel support, but they think this most likely refers to Airplay. However, since I have never noticed this behavior before, something must have changed either on the Roon side or the Hegel side. Maybe somebody here can provide me some more details.
Thanks and best regards,
