5.1 audio for projector/amp setup

[pfhastie]

I have the 2nd gen 4K Fire TV. It is rooted and all works more or less as I expect. HOWEVER, because the 2nd gen version doesn't have a digital audio link to connect directly to my amp (which is connected to a 5.1 speaker setup), I have been forced to use a USB to SPDIF adapter (Fanmusic FM-6011, but there are many alternatives available). It is a very solid adapter and works without issue whenever my projector is off. When I fire up the projector, however, the audio signal is sent directly to the projector's built-in speakers via HDMI and I lose the SPDIF connection to my amp.

I have tried all the available audio configurations in the Fire TV settings, but none of them make any difference. Given that the audio works when the projector is off, this surely indicates that the problem is not with the USB connection or the SPDIF adapter. Is there any setting or program or workaround that will allow me to send the HDMI signal to my projector and the corresponding audio via the USB adapter to my amp?

If not, is there a cheap gizmo that I may be able to source on eBay which will allow me to split the HDMI audio signal from the HDMI video signal? Such a shame that they decided to drop the audio port on the 2nd gen.

I'd be very grateful for any pointers from anyone who has any experience with a similar setup.

I had similar issues myself with my aftv2, wanting to have digital audio sent to my pioneer av system.
My pioneer av system is hdmi but unfortunately the hdmi part no longer works.
I stumbled upon a thread which advised of a certain gizmo what was exactly what I needed,
Here is the exact device I bought :

Look at this on eBay http://www.ebay.co.uk/itm/250970565434

The only drawback I had with this is its only 1080p, where as the aftv2 is 4k, so your limited to 1080p.
Not too bad as I cant tell much difference.

Oh, ye gads! Thank you so much. Yes, it was madness losing the digital audio on this version, but as long as there's a workaround, I can happily live with 1080p for now (it'll be a while before I can afford a decent 4K projector). A great help.
