Hi,

I have been away for the forum for a couple years, and when I was active before there was no such thing as Roku or any streaming device. So now I am excited to see what affect Roku has on BYT. So I have the new Roku 4, and since my projector has no HDMI input, I had to get a female HDMI to male DVI adapter. Got the video on the screen just fine. So for audio, i used the headphone jack that is on the Roku remote, and ran a cable directly to a powered Beats By Dre speaker. Problem....the audio was intermittent, kept cutting out, and the gain was so low even with the speaker cranked, that it was not useable. Has anyone had a similar experience, and what did you do? Can't think of any other way to get audio from the Roku, since the audio jack on projectors is an input, not an output. 

Any thoughts?

You need this:
http://www.amazon.com/J-Tech-Digital-Premium-Extractor-Converter/dp/B00BIQER0E/

I use it all the time to hook up cable/satellite boxes to the projector. It will seperate PCM (non-Dolby) audio from the HDMI signal and give you regular RCA outputs that go to your mixer and ultimately speakers.

Thank you very much for the suggestion. I was not aware that this type of device was necessary. My only concern is that I do not use a mixer. I would need to run from this device directly into the powered speaker which only accepts a mini-plug. With an RCA to mini plug adapter, do you think this will work?

Thanks,

The RCA output of this device is at a similar gain level as a regular DVD player. I always use mine with a mixer, but if your Beats speakers can take a DVD/Blu-ray input without problem, this should work too. If not, Amazon has a great return system.

I have been using an HDMI extracor to pull the audio from my chromecast so that I can run it to my analog audio (stereo cooler with marine speakers) input and the video over HDMI to the PJ (Epson705) or (Mitsu XD460 for camping)- with this setup I can travel with it all in the cooler and in the back of the truck to the camp site and not worry if it rains as its safe and dry inside the cooler :-)

I just hot spot my phone for the wireless network for the chromecast - plex fro the phone to the chromecast and use the phone for remote, volume, etc...works great!


extractor I am using

I am working on a video board to mount everything to so its even easier to just plug in and power up but will fit into a slot in the cooler and off we go - works well with the backyard last minute movies with an old WDtv box and a thumbdrive full of classic also  Grin

ver 1.0 for testing - power at base, analog audio and hdmi out on the other end - cheese prototype board...lol

The digital to analog audio converter KingPin posted will achieve the same result with your Roku, but I'd still suggest getting an HDMI extractor instead because it's more multipurpose. You can use it to with a 100' HDMI cable to feed video from other wired sources in your house such as cable or satellite boxes.
