Feature description:
Would it be possible to add an option, to disable volume control for a specific upnp renderer? This should allow the device volume buttons to control the system volume rather than the renderers volume.
Problem solved:
Upnp renderer has fixed volume output so symfonium volume adjustment has no affect other than blocking the volume keys from adjusting the android system volume. This would allow adjusting the android system volume while casting with symfonium
Brought benefits:
Release volume control back to the system when they are not needed for a upnp endpoint.
