    Default TV source or Speakers causing muffled sound?

    I am fighting this battle with tv shows not sounding all that good... All the shows I watch are in HD, some sound ok (not awesome, but ok-good) but others sound terrible like I am listening to my speakers from inside a box most pronounced with voices.. I recently swapped out Comcast boxes to the dcx3400 to see if It was that box that was causing it... I may have noticed a bit of change but there are still muffled tv shows.

    Blue-rays sound really good, and music sounds good when played from a good source... I have everything hooked to the receiver via hdmi cable and then from there the video is sent to the tv... I have tried swapping the hdmi cable from the dvr with no change.. I used the advanced mcacc setup to put all the settings in place..

    Is there something I can do to help with this... Should I look into upgrading my speakers (honest opinions... You aren't going to hurt my feelings)? Are tv programs just bad audio sources (do other people get the muffles when watching tv?)?

    I am not familiar with the cable box you are using, but here is what I have experienced with mine:

    Set the audio range to "narrow"
    Leave the source to "analog"
    If you have a seperate volume setting for the box set it to "max"
    HDMI sucks on my box. The picture and sound are subpar. I use the component video out and sound with digital coax. Works best for me.

    If your blurays sound great then there is nothing wrong with the speakers. Sounds like the source of the box. Messing around with settings on the cable box might help.

    Yeah, I think that some movies/shows are okay sounding, while others are horrible. I guess that they care more about video than they do about audio... keep in mind that there is more people that have HD tvs than people having a mid-fi HT setup and up (which is anything except a HTIB). Only my opinion, but I could hear that too!

    P-S: Have you tried connecting your HDMI directly to your receiver to see how it sounds, or using optical/coax out from your cable box to your AVR?

    It is currently setup as hdmi from dvr to receiver... It was setup as hdmi to tv to receiver via optical cable but that was with the old reciever... I have not tried sending the audio from the dvr to the receiver via coax or component, but I thought hdmi was supposed to be better ?

    Could also be the quality of the HDMI cable your using. Many have had issues with those 20 buck wallyworld cables. Though, if everything sounds good on other sources, chances are it's something in the cable box settings, or the cable itself from the cable box to the receiver.

    I ran mcacc a couple of weeks ago when I ran got the A7s an the A6. It did a TERRIBLE JOB! It left the EQ on which seriously distorted the sound. It also left me with a strong hissing sound coming from the tweeters.
    I turned the EQ off and redid all settings manually and i love it right now, at least while I play something.

    BUT,

    some of the hissing noise is still there! I don't know if I didn't notice it with the old RM7 speakers, but now it's here even when the computer is off.

    I had the same issue with my car's tweeters and the problem was the gain on the amp was too high.

    But now if I want to play music even moderately loud, the hissing is audible when the songs stop. I don't know what other setting for the gain this receiver has, but if someone can help I would appreciate it.

    On your issue, try switching between several listening modes on your receiver. May be some weird special effect is on.

    I get that sometimes too. It's the TV programming that is messed up usually, can't do anything to fix it.
