When I was waching TV using Denon AVR-2808 the sound went off. Decided to to check if the TV was in mute mode. still no sound. After that i restarted the AVR, now there is no sound or video. The only way i can have sound is trough direct stereo or pure direct. Still no video.
Try unplugging your HDMI cable from the AVR I would like to see if your AVR is trying to use HDMI out instead of the composite. Next try plugging each device directly into your television, this will isolate the issue and tell us for sure whether or not it's the AVR.

Before we play taps and throw dirt on top of the Denon, perhaps a bit more triage is in order. I'm not certain who the patient is. Especially when you have "speaker issue" in the title. Are you saying there are some speakers that don't work ONLY with BluRay?
If it has NEVER worked the (unnamed) BD player or its cable(s) could be at fault, too.
What 'connections' are we talking about. HDMI, coaxial- or optical audio, 5.1 analog; to what input on the Denon assigned to what function?
Have you tried all audio paths out of the BD player? Is it configured to squawk in the right digital mode?
Do you have any other digital audio sources (CD/DVD) you could use to certify the audio paths that don't work with the BD player?
In the 2807 the HDMI out is a video out only. Audio is not processed through the HDMI output.
If you are using speakers it is best to adjust the playback modes to stereo if you are annoyed with surround sound modes.
Please comment if I helped.
You can try this reset precedure below, but it sounds like you may have a DSP board problem. This is a new model of Denon, it should still be under Denon's warranrty, it has a 2 year warranty. If this does not help, you need to take it in to be serviced. If it is not under warranty, you will not like the cost of the repair. A new DSP board usualy cost about $300 and then you must pay for the labor. It is not cheap. This reset procedure has been know to work some minor miracles, lets hope it works one for you.
1. Switch off the unit.
2. Hold the following STANDARD button and DSP SIMULATION
button, and switch on the unit.
3. Check that the entire display is flashing with an interval of
about 1 second, and release your fingers from the 2 buttons
and the microprocessor will be initialized.
Note:If step 3 does not work, start over from step 1.
All user settings will be lost and this factory setting
will be recovered when this initialization mode.
So make sure to memorize your setting for restoring
after the initialization.
