Volume level changed?
This is weird and I don't expect anyone will come up with a definate answer but yesterday I noticed that the audio volume level that comes from my TV is much lower than it has been since I got the X1 box. I usually listen to programs thru an AV Receiver but there are times that I turn that off and listen to the audio from the TV via the HDMI port. My "comforatble" volume level on my TV is "6", but now I have to increase it to "12" to get the same loudness. I was initially concerned that something was wrong with my hearing but that doesn't seem to be the case. The sound level thru my AV Receiver via optical seems to be unaffected.
So, I'm just looking for an explanation, but I'm afraid it's going to be one of those things that someone tweaked and no one else notices or cares.
