Thanks Pyrrho for the response,
I doubled checked, and I am utilizing the ARC HDMI port on my TV to my receiver. I will check tomorrow after work for any possible audio processing that might be enabled within the TVs menu like you suggested. You mentioned that input level can have an affect on volume; is there any way to adjust this?
If we were talking about a normal analog line level input, the way to control it would be by controlling the output of the source. Since you are dealing with a digital connection, most times there is no way for you to control the level. And most times, there is no need, which makes your situation seem somewhat odd. In fact, my original thought was that you were using some variable line level outputs on the TV (which would have explained your TV tuner volume), but your TV does not seem to have them, which pretty much eliminated that option.
I'll see if I can update the firmware as well, but I just finished watching some Netflix and the volume seems to be normal within this app on the Xbox. I checked the other apps again, like HBO GO and Amazon Instant Video and those two apps played at much lower volume levels than Netflix and Slacker Radio. Could the apps themselves be possible causes for low volume? It still would not explain the low volume through live TV.
Yes, the individual apps and sites
can do whatever they want with the volume, though one would expect them to be sending a digital signal that is pretty standard. And when I run Amazon Instant through a Roku, the volume is normal. So I don't think that is where the problem lies. You might want to check your Xbox settings, though that will not explain your issue with broadcast TV via your TV tuner. But if you have some sort of special processing set for some apps and not others, that could explain things in the Xbox. (I am unfamiliar with the settings for an Xbox, so you will want to consult your manual for details on audio processing settings; all of the audio processing should be off [just send a straight or, if it won't do that, a simply decoded signal out], at least until we get your problem sorted out.)
Another thing to look into is the settings you have for different inputs on your receiver. This would not explain differences in different things running through your Xbox, but it could explain what is happening with your TV. Make sure that with your receiver's ARC HDMI input, you are doing a straight decoding, and not some sort of DSP mode (at least until we get your problem sorted out).
While we are trying to get your problem sorted out, I want to emphasize the fact that you will not hurt your receiver by turning up the volume control high to compensate for a low level signal. Assuming, of course, that you remember to turn it down before switching to a high level signal. That, and the fact that it is inconvenient and it should not be this way is why it is worth trying to figure out and deal with the problem. But a low level signal will not hurt your gear, and you can turn up the volume control to compensate without harming anything.
