Default 5.1 Surround sound help!

Hello everyone!

I have been struggling with this issue for quite a bit now...

I recently set-up my 5.1 Bose Lifestyle 12 II Series. I thought everything was set-up correctly until I ran a THX Surround Speaker test from the DVD "Incredible". When I ran the THX Surround Speaker test, I only heard testing tones out of FL channel, C channel and Subwoofer. No tones from FR channel, no RR or RL channel. Weird thing is when I watch TV or watch movies from my XBOX 360, I get sounds from all channels. It's only when I run the THX test, I get no feedback from FR, RR or RL. I checked all the lines and they are connected fine...
Does this mean I don't have 5.1 Surround Sound? What do I have to do to get True Dolby 5.1 Surround Sound?

The set-up is the following. Please advise what I did wrong.
Sound is output from Samsung LED HDTV using Optical (Toslink) to Bose Lifestyle receiver. But since the Bose system does NOT have Optical Input, I've used a converter: FiiO D3 Digital to Analog Audio Converter - 192kHz/24bit Optical and Coaxial DAC.

XBOX 360, Comcast HD Receiver are both connected to LED HDTV using HDMI cable. I've tried a different route by connecting the sound directly from Comcast HD Receiver to Bose receiver using RCA cables and using HDMI just for video and the sound was delayed. The TV sound was faster than Bose sound system creating an echo.

The Samsung LED HDTV only has two Audio outputs. Optical and 3.5mm headphone jack. What can I do to receive 5.1 Surround Sound? Any advice will be VERY helpful!!

Does your Bose have 2 or more digital (opical or coax) inputs?? From your description above, it does not..If so I would connect the xbox and Comcast box that way. And keep your HDMI connections to the TV for video and TV speakers. RCA (red and white) are analog audio connections and do not support DD 5.1 or DTS. You will only get 2 channel and sudo surround. It also may be the cause of the audio sync issue. And most TV's that I am aware of only support DD 5.1 and DTS via their optical output for the digital (ATSC/QAM) tuners. The rest are the same 2 channel and or sudo surround.

But if you Blose does not have any digital audio inputs, you are pretty much stuck with your current situation. Unless the Blose has a sync setting to fix that issue like many A/V receivers do. That converter only allows you to convert the connection. It does not allow for true DD 5.1/DTS. Sudo or Dolby Pro Logic is not bad for surround, just not as good as DD/DTS....

Thank you for your quick response. I really appreciate the help.

I just found out that according to the manual, the Bose system has a Coaxial Digital Input. But I'm not sure how to hook this up...
The below is from the manual:

"Setting up a digital sound source:

Connect a DTV or DVD player’s digital signal directly to the female RCA jack on the audio input cable. Connect the DVD player’s analog signal output to the AUX inputs. If your
Lifestyle system receives a valid digital signal (including PCM or Dolby Digital bitstreams),
this digital sound is used. If no valid digital signal is received, then your system selects the analog signal being sent to AUX, which is then processed by the Videostage decoder for excellent home theater sound. If your digital audio source has an optical connector, you will
need an adapter with an RCA (coaxial) connector. Consult your dealer or contact Bose"

I'm not sure how to use this Coaxial input from the Bose. From my Xbox 360 which I use it for DVD, I have it connected to my TV via HDMI. For my Comcast HD Receiver is also connected to TV via HDMI. All sounds come directly from Optical to Adapter(RCA) then to Bose sound system. Do I need a Optical to Coaxial adapter to plug into this Coaxial input on the Bose system?

Please advise. Thank you!

If it does have a digital coax connection, you can use an adapter like this below. Usually, the digital coax is a single orange or black rca connection (I think Bose is black). If your TV is 1 of the few that supports DD 5.1/DTS through the optical out for AV connections, then that would work. If not, you will be in the same boat you are already in. Or you can yous the adapter to connect 1 device like your xbox directly to the Bose for DD 5.1 with games and DVD movies. They are only around $15.. Your Cable box may have a digital coax out, if you would rather go that route if you would rather connect that vs. your 360 (360 only has optical out).

Thank you for the advice again.

I just recently went out to Radioshack and bought a Optical to Coaxial adapter just like the one on the website you sent me.
So the wiring set-up is the following:

Comcast Digital Receiver -> HDMI -> Samsung LED HDTV
XBOX 360 -> HDMI -> Samsung LED HDTV
Samsung LED HDTV -> Optical (Audio OUT) -> Optical to Coax adapter -> Coax input to Bose Lifestyle 12 II receiver

With the set-up above, when I run the THX Surround Sound test, I now hear testing tones out of RR and RL channels. However, no testing tone out of FR channel. To make sure, I checked the wiring and played a DVD and there is no wiring mistake. When I play a DVD or watch TV, there is sound from FR. But no testing tone...

On a second note, I have a SPDIF setting on my LED HDTV. It's under PCM setting now but when I try to switch to Dolby Digital setting, it is grayed out and it won't let me switch over to DD setting option.

What's my next option?

Thank you again.

That is probably because it only supports DD 5.1 via the TV's built in digital (ATSC/QAM) tuners..

The next step would be to connect up the 360 directly to the Blose via the optical/coax connection for audio. Now when you fire up a movie or game that supports DD 5.1/DTS, the Bose should detect it and display as so. If so, that is you only option. Or you can take that converted optical/coax cable and connect it to a manual optical switch like this or try a optical spitter that may work as long as only 1device is powered at a time.

Or a manual switch like this if the splitter gives you issues.

I referred to the Samsung's owners manual and apparently the Optical out only supports two channel audio...

So here is what I've changed:

Digital Comcast Cable Box (Has optical and coaxial outputs) -> Coaxial -> Bose Lifestyle

With the option above, I hear the difference in 5.1 DD Surround Sound quality where DD is available. It looks like I didn't need the Optical to Digital Coaxial converter after all... However, I did come to a small issue where I have to manually change the Coaxial cable from Digital Cable Box to XBOX 360 since the Audio is coming directly from the source. (ex. Digital Cable Box/XBOX 360/DVD player/PC)

Is there a Digital Coaxial Splitter or a switcher where I don't have to change this Coaxial input to my Bose every time I switch the source?

Yeap, as suspected. Your TV will only do DD 5.1 via it's internal digitla tuners.

I would think you would rather have your 360 connected for digital surround sound for movies in games over your cable box.. But since the 360 only supports digital audio via HDMI or optical, you will need the coverted optical/coax cable for that. If your fine with just your cable box for DD 5.1, just take the converter back to RS for a refund.

But if you want DD 5.1 with your 360, you will need that optical/coax converter. Since the 360 does not have a digital coax out, a coax spliter would not matter. But if your cable box also has an optical out, you can try a simple spliter like I linked above. They are hit and miss and you can only have 1 of the devices powered on at a time. Or you can use the manual switch option..

If your cable box does not have an optical out, you are pretty much stuck swapping the start coax cable and converted cable between the devices.

Thank you for the help! I really appreciate it.
XBOX 360 does not have Coaxial output but it has Optical output with another adapter... (I think I bought over 4 different kinds of adapters this past week) So I will have to go buy another adapter for the XBOX 360, but if I go with the Optical manual switch option you listed above, I will still need the Radio Shack Optical to Coaxial converter since the Bose system only has 1 Coaxial input.

I just ordered the Optical Manual Switch.
Once I set-up everything correctly, I will make another post to the forum and let you know how everything went.

Thank you again for your help. You get an A++ for assisting me.

So you have the older HDMI 360 that you need that adapter if you want to use HDMI and optical simo??? The newer model have the optical off to the side so you don't need that. I assume the adapter does not had digital coax (doubt it since no Xbox's do).

If this is the case, yes you would need the 360 adpater, plus the coax/optical converter.

Or just same all your dam converter money and ditch the Bose headache and put it towards a real SS system with ample inputs....

Like this for around $350 shipped.... Merry Christmas to you..

Do you have an older 360? If so is this the $5 adapter you need??

UPDATE:

Last night I bought the HD adapter for XBOX 360 and plugged it in to Optical to Coaxial Converter to my Bose. I ran the THX Surround Sound test and now I hear tones from all the channels!
Mission Success!! hahaha... Thank you. I now have True 5.1 Dolby Digital Surround Sound.
It is pain in the butt to manually switch the Optical wire from XBOX 360 to Digital Cable Box every time... But it's only temporarily.

Thanks for your help!
