Q: Help connecting a Macbook Pro to a Epson EH-TW480 projector with sound

This is about connecting a Macbook Pro to a Epson EH-TW480 projector.  I need it to play videos but can't get sound - the HDMI connector through a MDport gives picture but no sound.  Epson said use headphone socket but this doesn't work either.  Help. I get both with USB but the video is jerky (it can't keep up.)

 

I've done all the obvious checks like volume and connections - and I know the projctor's sound workks as it did on the HDMI-HDMI (to a Mac midi) in the showroom, and it does for me with the USB (but becasue the video is so poor, it's useless).

 

Thanks

    Are you using a single-piece Mini DisplayPort to HDMI adapter, noi a DVI adapter with DVI to HDMI adapter?

     

    Does HDMI show in the Output tab of Sound system preference?

    I'm using a NEET adapter from the MAC dislay port to HDMI

     

    In Preferences, it shows up as EPSON Projector UD audio, but beneath shows 'The selected device has no output controls'

     

    If I can get a single piece without an adpater, is that likely to work?

    If you mean this adapter

    <http://www.amazon.co.uk/DisplayPort-Adapter-cable-Apple-Products/dp/B002ERBFYM>

    it should work,

     

    "No output controls" is normal for digital audio, such as HDMI.

     

    Is Volume turned up on the projector (pages 34 and 61)?

    <ftp://download.epson-europe.com/pub/download/3734/epson373434eu.zip>

     

    The projector has separate volume settings for each input.

     

    The HDMI adapter or cable could e bad.

    The adapter/cable you show is the one  - picture good, sound zilch. 

     

    Sound from headphone/phono - any other that the HDMI setting says no signal, so not sure how this can have  volume setting. 

     

    On the audio cables/adapter themselves - the only way I have to check them would be to buy new ones as I don't have anu other ways of testing them.  This I'm trying to do - though the headphone-phono lead is new.

     

    Does the mini diplay port  take sound?  I have a separate Mac monitor that i use that is connected to my MacBook , and the lead that comes wth the screen has a display port image for picture and a separate USB cable that carrie the sound.  Needless to say, I've tried this combination on the projector but it means setting the projector to USB and back to the juddering video. I reported this to the online Epson help and the conversation went:

     

    Agent (Gillian Owen): "Instead of the USB you would need a cable connected to the Audio in port on the projector to have sound when using HDMI form the Mini display port"

    richard: "aha - is that the phonos red/white?"

    Agent (Gillian Owen): "It is the two directly above where the power cable connects."

    richard: "and will it take the sound from the headphone out?"

    Agent (Gillian Owen): "Yes"

     

    SO ......?!  I'm stumped!

    PS

     

    I've been continuing my Clouseau-like investigations.  The Neet website says that any MacBook over about 2 years does not carry audio on display port (the route to the HDMI).  So that probably solves/closes that avenue. 

     

    Using the S Video input setting, I am now getting sound - but it seems impossible to get both S Video (for sound) and HDMI for picture.  It's one or the other (I don't have a cable to S Video picture, but doubt that'll carry video successfully if UDB didn't.)

     

    So what's needed is a way to make the S Video (audio) AND HDMI sources play at once - and I'm beginning to think this is not possible.  If you can inspire me to thinking differently, I'd be really pleased.  As it is (for a presentation tomorrow) I'm preparing to use separate speakers (pah!).

    Check here to see if your MacBook Pro supports audio from its Mini DisplayPort:

    If it doesn't, you can add the audio from USB:

    Do you have a TV with HDMI?  If so, see if it gets audio from your computer via HDMI.

     

    Have you tried the volume control setting on the projector when connected via HDMI?

     

    Do you have a Blue-ray or DVD player with HDMI to try with the projector to test audio via HDMI?

    I'm concluding now that my Mac Mini Display port doesn't do sound (it uses a separate connector for sound to my separate screen).

     

    But I have checked the volume while connected to HDMI and it's set to high, plus varied it.

     

    Getting the audio from the USB or from the phonos (S Video) is the same issue I think - they need to be chosen as source and I don't see how to get HDMI for pcture while also USB or S Video source for sound. It seems to be one or the other. 

     

    The projector ran HDMI-HDMI OK in the shop where I bought it, so I know it works.  Just wasn't expecting it to be so tough wth anything else.

     

    Thank you for your persistence!
