OPTIK TV - No Audio

Reply

I don't have any audio after turning on the cable box/TV/receiver/amplifier. There is video, but no audio. After re-booting the cable box, there is audio. I obviously don't want to re-boot numerous times per day and I hope there is a solution. This situation has just recently happened within the last week. Has anyone else experienced this situation?

Are you connected over HDMI through your AV receiver?

Optik -> AV Receiver -> TV

Some AV receivers are finicky about HDMI handshakes and may require a certain order for powering up. Powering up Optik before TV or TV before Optik or powering up AV after both TV and Optik are on can have different results.

 

Try connecting directly from Optik to the TV as a test to see if the audio problem persists.

@xray ‘s solution addressed my issue. For some reason, after a recent update, the handshake to my audio system would not address audio on restart, and required a reboot. Connecting directly to the Television fixed it.

I have this same issue.  We got Optik TV last week and the installer was unable to figure out the issue.  But I have to reboot my optik box (<settings<restart box) every time we want to watch tv.  I have bought all new HDMI high speed cables and have it hooked through a newer Denon amp.  I have tried an Optic cable with no luck either.  It does not matter if they are digital channels, PRV or standard def.  If I only turn on the Optik and the amp I always have sound.  As soon as I turn on the TV I add video and the sounds shuts off.  If I restart the optik box and leave everything else on (and change nothing) once it is done rebooting sound comes on and everything works with video and sound.  It works perfectly until I turn off the Optik Box and then have to do the hard reset again next time.  I have tried turning on and off in different orders with no change.  But as soon as you turn off the Optic box it will not handshake with the TV again without a hard reset.  I have searched LG support, Denon Support, and Telus support with no luck beyond this thread.  I do not want to connect directly to my TV as the reason I have an amp is to enjoy my surround sound speakers.  Any thoughts?

If you connect the Optik box directly to the tv and leave out the Denon receiver does it work?

I had a similar experience with a Sony surround sound system. Ended up connecting directly to the TV, and using the Optical output from the TV to the sound system.

Yes if I go direct to tv it works. But then I have to use optical cable to Denon and have no Denon settings on my screen and sound is not great. The weird thing is if I turn on Optik and Denon sound is fine then turn on tv and sound is gone. Leave tv and Denon on and restart Optik box and all works perfect.

If connecting the Optik box to the TV directly has no issues then clearly the problem is with the Denon receiver. You may want to check out the Denon support forums or a site like avsforum.com to see if anyone has found a solution.

 

Have you checked to see if your receiver has the latest firmware?
