Chromecast

Recommended Posts

 

I have no t.v. in my theatre room, only an Epson EH TW projector with Actiontec transmitters.  What I have been doing is watching t.v. through my Teac PVR, with the HDMI plugged into the transmitter and PVR.  I have a soundbar plugged into the PVR for audio.  I purchased a Chromecast which I plugged into the  Actiontec transmitter and PVR, so I can watch Netflix etc in the theatre room.  Installed just fine via mobile phone and tablet, and have a fantastic picture.  However I am at a loss as to how I can get sound through my soundbar.  I have tried using a 3.5mm plug from mobile/tablet to soundbar, but just picture with no sound.    Actiontec transmitters does not have any audio out sockets.   Any assistance would be much appreciatedl.

Hi neishah,

I think you need an HDMI to Audio converter. You could then use the HDMI OUT plug on the Actiontec transmitter to send an auto signal to the sound bar.

Something like this maybe. Full list here

Note that you will need a powered converter. There are passive cables (much cheaper - like this) that have HDMI on one end and RCA sound cables at the other but they only relay the digital HDMI signal, they don't convert the signal to something the soundbar can understand.

PS You may also pref using optical to your sound bar (better quality sound). Then look for an HDMI to optical converter

Thank you so much Peter, that makes sense.  However just one more question?  I have a HDMI going out to the PVR (so vision is enabled on the big screen), and the Chromecast plugged into the other HDMI slot of the transmitter.  Where would I plug the powered convertor for audio?

Epson EH TW

Which model?

I assume the soundbar has no optical input then or is this what the PVR is using?

Soundbar is plugged into the PVR with the red and white audio plugs.  There is an option for optical on the remote, but having never used "optical" am not sure what to do with it.

Optical is a different cable type. It would give a bit better sound I believe than the RCA you are using.

If you plug the Chromecast into the ActionTech transmitter can't you just watch that on the projector or TV with sound?

If the soundbar is plugged into the pvr, wouldn't that mean the pvr would have to be plugged into the transmitter?  So what is suggested is that I purchase the powered convertor, plug that into the transmitter HDMI, then the Chromecast into the second HDMI on the transmitter, that should do the trick............ so I don't really need the pvr at all?

I'm not 100% on the workings of the Actiontech. But if I get it correctly, there are two HDMI ports on the transmitter. One is input, but the other is output.

So in normal circumstances you should have

1. the PVR HDMI going to the ACTiontech INPUT

2. The PVR RCS going to the Soundbar input (Sound)

3. the actiontech OUTPUT HDMI going to the TV input 

4. That way anything watched via the PVR can be seen on the TV and/or big screen

Is that correct?

If that's the case then to watch Chromecast you would:

1. Plug the Chromecast into the transmitter input.

2. Plug an HDMI cable into the transmitter HDMI output

3. Plug the converter box into this HDMI cable

4. Plug the converter output straight into the sound bar

That might involve a bit of cable swapping so the following two things should make it easier:

1. Use an OPTICAL converter. That way you just switch the soundbar to either RCA or OPTICAL depending on the sound source (no need to unplug anything)

2. Get a HDMI switch so you can select either the chrome cast or the PVR as the HDMI INPUT into the transmitter (Something like this or this)

Sorry you have to get more gizmos.

PS Suggest you draw a diagram and arrows showing where the cables all go if its hard to visualize.

Your With Chromecast is a bit wrong. The HDMI cable between the PVR and the ActionTech should not be there. The Actiontech HDMI output will be a HDMI cable that plugs into the converter and then directly into the soundbar (PVR is not in play when using chrome cast)

Try drawing up my solution above (with switch and converter and chromecast and TV and Projector and Transmitter in place)

You mean RCA? That's fine. 

With only the two plugs then perhaps a HDMI to jack converter is the best bet (as presumably the RCA are already in use?)

Something like this?

Diagram good, but now expand it out to include the Jack and RCA plugs at the back of the soundbar and the HDMI switch (which the chromecast and PVR will plug into)

PS Got to go. Will check back in tonight.

Thanks so much Peter, I had to go to work sorry.    After work, I did drop into our local hifi  chainstore, but their words "Projectors aren't very popular anymore, due to the great quality t.v.'s these days"............ they didn't have what I needed.    They have directed me to another store, which I will try on Friday.    What you are telling me does make sense to me, hence why I am just going to purchase what you suggested.   I have nothing to lose hahahaha  

Will let you know how it goes on Friday, thanks again for your advice and patience!:D

No probs,

I think you may find local options are few and far between. For one thing these converters seem to be mostly on overseas eBay sites rather than local. Also HDMI => 3.5mm Jack Converter isn't a popular type. Jaycar (which specialises in electrical dodads) only has the HDMI => RCA converter and it costs $130!

If you have got an eBay account I'd suggest that unit from above would be pretty painless to get delivered. If you want to save yourself a trip to the store just give them a ring and ask if they have any HDMI => powered audio converters (and what type are they - 3.5mm headphone jack, RCA, optical). No need to get in to projectors v tc etc. :)

Good Luck

Hi Peter,   I have it all set up,  bought a hdmi convertor box from Jaycar for $80, and it's done the trick.   Thank you so very much for all of your advice and patience:D
