[PROBLEM] volume via rest api doesnt work with multiroom

[LeGuiz]

Thanks for the fix !

Sadly my problem is not solved even after the latest update.
There is a tiny improvement tho.

The situation before the update was :

Volume is 25 in real sound and in UI
I send curl command to raise volume by 5 via API
Volume is still 25 in real sound and in UI
I click on UI + to raise volume, it raised to 31 directly in real sound and in UI.

What happen now after the latest update :

Volume is 25 in real sound and in UI
I send curl command to raise volume by 5 via API
Volume is now 30 in UI but the real sound as not been raised.
I click on UI + to raise volume, it raised to 31 in UI and in real sound.

is there any way I can help to solve this ?
