Pavilion S/PDIF output

Hi,
I have dv6623cl. According to HP, one of the headphones jacket can transmit digital audio by connecting a coaxial 3.5mm to RCA cable. I installed WinXP instead of Vista. I had no success with the S/PDIF output. Did someone succeed ? I see no specific switch in the Realtek control panel to use digital output instead of headphones/speakers... (I'm using the WinXP version of the control panel).

Thanks in advance.

 

Anyone has an answer?

 

You can try to search for realtek drivers either from HP or from some other manufacturers. I think HP dv6x00 from before the santa rosa debut used conexant audio chips and drivers so even if HP had drivers for XP with the functionality, they'll most likely not work.

 

Um, that's an optical jack, not a coaxial jack.

You need an optical audio in on your receiver, and a 3 1/2" optical audio cable for that to work.

 

mark2000, Are you absolutely sure it's an optical socket and not a standard coaxial S/PDIF?

BTW, I already have the latest Realtek drivers for my laptop with WinXP.

Thanks in advance.

 

Unfortunately, I'm almost positive. I've never heard of anyone saying that this jack is coaxial. I have the dv9000 and it is optical.

What you could do, is find a small plastic object, such as the inside of a pen, and put it inside the jack and touch it around the edges. I believe if you touch it on the right side of the inside of the port, you will see the glowing red light turn on, which is the optical transmitter. The optical transmitter turns on when you stick somethign in the port.

Tell me what you find.

On the other hand, if anyone can back me up on this, let me know, I'm curious to see if I'm right.

 

Thanks mark2000. I'll try what you suggest. One question though, what socket is supposed to be the digital? 1 or 2?

 

It should be the one that says SPDIF beside it. On my machine, there are three ports, microphone, headphone and SPDIF. My SPDIF optical is the one on the right.

 

Hi again, mark2000.
I bought an optical cable but it didn't work. When I plug it in, nothing changes and the Realtek control panel detects this as standard analog headphones... What do you think the problem is?

 

My experience with this type of setup (mine is an HP tx1000) where one of the extra analog audio jack doubles as a S/PDIF audio port is this is an optical jack. One would think it was a 3.5mm digital coax. Nope. Mini-TOSLINK. My DVD is sending Dolby 5.1 out to my A/V reciever right now. The jack does not "sense" a TOSLINK is poked in there. You need enable digital output manually.
In Vista:
Right click on the Desktop. Select Personalize. Scroll down to Sounds. Click it. In the Playback Tab, doubleclick the Realtek Digital Output icon to get to the Output Properties. Click the Supported Formats. Checkmark all the checkboces for Encoded formats and Sample Rates. Click Ok. The Realtek Digital Output icon should now have a green checkmark beneath the icon.

If everything transpired as I just described, and you still aren't hearing any sound, go back to the Sound applet Properties and click on the Advanced tab. There will be a green right arrow button to the right of the sample rate drop box. Click it and you should hear the left speaker chime, then the right. If you still don't here any sound at this point, but there is indeed a green checkmark beneath the Realtek Digital Output icon, then the problem is elsewhere. Try a good known TOSLINK. Test on a good known A/V reciever that has decoded digital audio beforehand. The problem lies downstream of the laptop.

 

And make sure you have all the Vista Updates and HP hardware updates. Maybe a BIOS update for good measure.

 

Thanks for your extensive solution. The problem is that I have WinXP installed with the latest Realtek drivers (they are different however than Vista's drivers)...
And I have the latest BIOS...

 

Is someone using SPDIF with dv6500 series and WinXP? I have dv6623cl
I can't get this working. Is it possible that I don't have SPDIF?
There are 3 sockets: 1 is for mic and the rest says headphones 1 and 2.
