I’m having an issue with controlling my Samsung TV, model UE40JU6445
HA sees the TV and when I change volume, via my remote control device, the volume slider in HA is changed accordingly.
But when I try to change volume from the slider in HA, nothing happens.
The log files give below error:
ERROR (MainThread) [homeassistant.components.dlna_dmr] Error during call async_mute_volume: UpnpActionResponseError('Error during async_call(), status: 500, upnp error: 501 (Action Failed)')
