    Default DisplayPort carries audio?

    I have a Dell 2408 monitor connected to my M6400 via the display port but there is no audio going thru to the built in speakers in the 2408? Has anybody been able to accomplish this. Is this an issue with the M6400's port not carrying audio...or the 2408 not able to pull the audio from the display port

    I have 3008 and I can only get audio on HDMI, not displayport. I couldn't tell you if it's laptops' problem or display problem.

    It can carry audio, It could also carry multiple video streams. My Latitude E6400 connected to 3008WPF via DisplayPort with Dell Speaker Bar plugged into the headphone jack and powered from the monitor, I do not have audio output. The audio plays only on the laptop.

    It could just be a driver issue, but I would not expect audio support anytime soon.

    You do need to manually change the audio output to Digital Out (I think that's the label, might be High Definition or something).

    I just ran a couple more tests. My digital audio appears to be on by default, I am not sure where the setting that you are referencing is located. I have the IDT audio drivers. I just tried a DisplayPort to HDMI converter and still have the speaker bar plugged into the audio out on the monitor. No sound. Blu-ray Player to the HDMI input has sound.

    In control panel, under sounds, right click the option other than speakers/headphones, and select set as default.. If that's already done.. then it could be a driver issue..

    No way to do this in XP eh? I don't see any of these menu's in XP SP3 on my E6500.

    YES, it carries audio!
    I'm using it through DisplayPort->HDMI adapter connected to my Marantz SR4002 AV receiver. I can get stereo PCM as well as AC3/DTS passthrough.

    To enable it in XP, check both "PC speaker OFF" and "SPDIF" in volume settings.

    The question was if you can get rid of an audio cable, when you use a pure Display Port connection. At the moment most monitors don't support audio over DP. When you use a DP-2-HDMI adapter it's no suprise that audio works (that was already said in the 2nd. post )

    My post was mainly addressed to jwerx to confirm that it works fine in XP.
