The analog audio output of the DVR is only applicable to the 2-channel L/R-stereo audio output (i.e. the red/white RCA connectors). This applies to the "volume" (of the DCX audio output), matrix/surround processing, compression, etc.
It has zero control over the digital audio output that goes over HDMI or optical, to your AVR system or HDTV speakers. The digital audio is delivered "as-is", untouched. It is the destination audio component which then handles the decoding, amp, output level to speakers, etc.
So when you say "when I switch to it", are you feeding 2-channel L/R-stereo analog audio from DCX to your speakers? If so, then it's the DCX internal audio amp system that is in control. But if you're feeding digital audio from DCX to your sound system, then the DCX is not really involved.
Note that a common complaint is that the audio levels on many channels are not the same, so that changing channels might cause you to turn up the volume if you arrive at a low-level channel. But then if you change channels to a high-level channel, you get blown out of the room.
This is just the way it currently is. Even worse with commercials (especially locally inserted spots), which are often MUCH louder than the surrounding program content.
