Not getting sound from my Denon AVR 3300 receiver? Video works, but no sound.

I understand, it's something I've misunderstood on my denon avr-790 as well when connected to a samsung 8000 series led tv.
The answer isn't in the receiver's settings (you can be on whatever source you want on the receiver end when toggling the menu). You need to toggle through the tv's sources to find the menu (usually found on hdmi 1). I've spent towards an hour recently troubleshooting only to find that it was the tv's source that wasn't set properly and I was trying to change the receiver's settings instead of the tv's source.
Hope that helps!

I would recommend using only HDMI. That's what the cable was made for!

The best audio for any source will always come digitally from the first device in which it appears. The Cable Box would be that device.

Hi,

• if you want to listen your TV on your Stereo system thru your receiver, AVR-3300 ** you need to connect "Audio Output " RCA jacks or "Optic cable output" of your TV
  

** to "AUX input " or "TV" OR "Any input" of your receiver ( except Phone ) or "Optic Cable input"
** than just switch to respective mode on AVR-3300 RECEIVER corresponding your RCA or Optic connection...
There you go..Your TV sound is on the AVR-3300
Receiver..By this means whatever you watch on the TV (tuner, satellite , Xbox ) ,it's sound will come thru your stereo..

• Hope this helps!

TV's are not your best source of audio. Get the TV-related audio digitally from the source, NOT the TV.

hi there, i don't have a solution unfortuantely, but i may have the same problem. I have a denon 2802 av receiver, i bought it second hand and I can't seem to get the component video in / out working. Are you supposed to just plug it in and it works? Because I can't find any buttons or settings to select component in / out as my input / output sources?

about $150

After days of frustration the real problem was with the cable box. It needed a firmware update. Following forum advice I disconnected the cable box power cord for a few minutes, reconnected it, allowed the cable box to reinitialize. Turned off receiver and TV. Turned TV back on and set it to HDMI connection, turned on receiver and all worked fine. Great picture and sound.( Needed to buy an optical cable to go from the cable box to the receiver to get sound from the speaker system. )--the dirtybird

Do not use the ext in plug into the aux, or video input of the denon

the hdmi does not carry sound on the box its only a pass through, if you want digital quality sound it has to go through dig coax, or preferably optical(toslink)
