I want to connect my Macbook Pro (Mac OS 10.5) with my Onkyo Receiver via Toslink optical cable. How could I do?

Your receiver appears to have a digital optical input, so no converter would be needed, just an optical fiber cable (TOSLINK) between the two optical ports. However, the manual for your receiver states that several functions don't work unless there is also an analog connection. If you must have those, you can use an HDMI audio extractor. You may also need an adapter cable to convert 3.5 mm stereo audio to a pair of RCA phono plugs to make the analog connection.

use the optical port (toslink cable needed)little square with flap will be lit red or use rca cables red and white audio out fron tv to any port on reciver(aux,cd,dvd,ect) the reciver will have to be turned to this for the surrond to be heard

Use the TOSLINK - the optical/digital connector on both devices.

The problem is that the headphone jack for you Macbook Air is a copy Analog (standard headphones) and Optical (toslink) jack. The jack has a small microswitch that detects when the cable inserted into the jack is a metal analog connector or a fiber optic toslink cable. The reason your seeing the "NOT ALLOWED" sign (circle with a slash through it) is because you cannot not adjust the volume on the sound when the output is in DIGITAL MODE. To verify this, drop down the jack cover on the side of your macbook air and place your index directly in-front of the headphone jack about 1/2" away from it. Is you finger glowing red? That's because the fiber optic LED is turned on and Mac OS X thinks that there is a toslink cable inserted into the jack.
This is a known hardware problem with that type of combo-jack and affects a lot of other Macbooks, as well.
If your Macbook Air is still covered by Apple Care, take it into an Apple store and have them replace the jack. I know this is a pain, but it is the correct answer.
If your Macbook Air is NO LONGER UNDER WARRANTY, you can attempt to fix this yourself, but be warned, you could break stuff!
Here is a thread at the Apple support forums discussing this issue: http://discussions.apple.com/thread.jspa?messageID=3255575
The above link is good background reading and will help you understand the issue further. The short answer is that many people have inserted a toothpick (other similarly sized NON METAL object) into the headphone jack, wiggled around until the microswitch is clicked off, then normal audio resumes. My 2009 Macbook Pro 17" has the same issue, but I have found that I can take a regular pair of headphones, insert the jack, wiggle it, remove it, reinsert, remove it....and repeat this process until the switch gets toggled. It's annoying, but I have to do this until I get home and can send it back to Apple for warranty work.

The TOSLINK optical connector is almost aquare and should be the same on both blue-ray and on the receiver. There are 4 orientation you can try and only one fits. Blue-ray can have the connector installed rotated, but it should be the same connector.

Looking at the cable at Amazon I can see that it is the correct cable. If it really doesn't fit, maybe you have damaged cable or damaged connector. Try the other end of the cable and/or other optical input on the receiver.
BTW there is also combined analog/optical jack connector. It looks like normal jack socket, but accepts also optical signal. But this is not called Toslink and usually is not used in home theatre devices.

Connect external speakers, headphones, or optical digital audio equipment. The headphone / line output jack accommodates optical digital audio output, analog audio output with a 24-bit, 44.1-192 kHz D/A converter, digital audio output up to 24-bit stereo and 44.1-192 kHz sampling rate and supporting encoded digital audio output (AC3 and DTS). For analog headphone / line output a standard audio cable with 3.5mm metal plug should be used. For digital audio, a standard Toslink cable with a Toslink mini-plug adapter can be used.
You can find the Digital to Analog converted:

Max does recognize receiver over HDMI-CEC.
The problem is that DVI output is for video only. Macbook won't (and can't) output audio via DVI. So yamaha receives only video signal via the HDMI connector. You can check that by pressing Option button on yamaha remote and choosing Signal Info - you will see info about video, but no audio signal present.

I know nothing about tivo but dvd player might need to be on bitstream to pick it up.I have to change mine when listening to music. hope this might help.

Normal 0 Try disconnecting the Mouse Receiver from the USB port and reinstall the CD software program. When the program asks you to connect the Mouse Receiver to the USB port, do so and it should work.
Hope this helps. Bud

I have the same problem except i'm using a macbook and i'm trying to connect the speakers. My macbok accommodates optical digital audio output, but you have to buy a  a standard toslink cable with a toslink mini-plug adapter.  Since the speaker input is a digital coaxial (not fiber, optical) you have to buy a Digital Fiber Optical (Toslink) to Digital Coaxial (S/PDIF) Converter.  good luck. hope this helps
