My player wont output sound, it plays the mdbut no sound. all connections tryed (analgue,optical. when playing mono comes up on display. can you help

To play sound via an optical out, you must have an optical lead connected to the device and then it must be connected to a device with an optical in option for you to hear it. The optical lead will have a light coming out of the end when you have connected to the out device. That way you know it's working. Each device will also have settings that switch on the optical system too. They are mainly used to connect sources for the playback of Dolby Digital, though some CD players have these connections.

Hi Denni, the TV should not be a factor. Is the CD player connected to the receiver. It should be playing out the receiver speakers. Thank you, Onkyo USA

The optical connection (SPDIF) doesn't have enough bandwidth to transfer DTS-HD audio. To use DTS-HD, you must connect the blue-ray player and receiver via HDMI cable.

Each DTS-HD audio track on blue-ray includes also "normal" DTS audio, which is probably used when you select PCM. Player decodes it and sends decoded (non-HD) audio via optical cable to receiver.

Hi.What kind of audio output connections does your TV have?
If it has mini jack output, you should use this cable:
If the output is RCA you should use this one:

Hope this helps.

What connections are you using for the DVD and VCR output for both the video and audio?
If you are using a "digital" signal (such as optical audio/HDMI/etc) the VCR audio will not pass through these outputs. You will need to connect up the analog (red/white) RCA connectors on the back of your unit to hear the VCR audio
I hope this help, Magoo

I have the same system. I have a Lifestyle and a Sony TV with a Samsung Blueray player. I also have an X-box 360, plus my pc with all my CDs (I-tunes) plays through my bose. Do this:

1. Use the optical cable for the blueray player to the Bose (AUX).
2. Use a digital audio cable from the cable box (either black or orange output) to the Bose CBL-SAT digital input. (it's a single audio cable)
3. For my PC, I'm using a digital cable from the pc to the Bose. I'm using the TV output because it's empty.
4. For my x-box (which I'm not too happy about) I'm using regular red-white audio cables from Bose TV input directly to the TV audio out. (You can play all of the above through this channel, but don't).

I figured the most important high quality sound should come from the blueray player and from watching regular cable tv. For picture, you should be using all HDMI connections.

Hope this helps.

Just first clean the optical lens of the unit. use a cd optical disc cleaner for this.

Simplest solution, from experience: make sure your headphone jack is pushed all the way into Zen 3.5 output jack. Sometimes it will feel like it's clicked in but you need a little extra push to get it all the way in.
Another thing to look at: I pretty sure the is a preference setting that controls right/left balance (my son has my Zen right now). If you can find  this control, it could be set all the way to one or the other side.
Give it a try, or see if resetting zen helps.
Good Luck.

Have you tried setting the PS3 on linear PCM output instead of bitstream? The DVR 50 may not say Dolby Digital since the optical cable goes directly from the PS3 to it but you may get the surround channel output you're looking for.

Combo DVD/VCR players don't output the VHS with Component Video. Most of the time, it won't output over the S-Video either. The high end outputs are ONLY for DVD output. You must run a yellow wire, or use coax cable to get the video. Same goes for the optical digital sound out. It's only for DVD use.
