The forum software that supports hummy.tv has been upgraded to XenForo 2.0!
This is a major upgrade which changes the look and feel of the forum somewhat but brings a host of improvements too. Please bear with us as we continue to tweak things and report any issues or suggestions in Site/Forum Issues.
So are you saying that the volume control on the HDR has no effect when you are listening via the optical output? and is this still the same if you have Menu > Settings > Preferences > Audio > Digital Audio Output set to Stereo?
