HEOS 1 HS2-speakers cannot adjust volume when paired

[kristianrl]

I have two HEOS 1 HS2 speakers which are in stereo pair, which means the two speakers act as one. They are then both named 'Kitchen', and are shown as one in the HEOS app.

AirConnect shows them twice, and is able to play music using either. The music is then played on both.
However, when adjusting the volume on the iPhone, the speaker volume is not adjusted accordingly.

When the speakers are not paired, the volume can be adjusted.

Let me know if I can provide log information etc. I am running AirConnect in a Docker container. You can treat this issue as low-priority. Thanks a lot for developing AirConnect!
