HDMI to Toslink or Coax Digital Audio

Sun Sep 02, 2012 3:44 pm

So my receiver doesn't have any sort of HDMI input. Presently, all my HDMI devices hook up to a 4 port HDMI switch which then goes to my TV. This is mostly fine except it means that if I want to listen to audio, I have to leave my TV on as well :(

I'm trying to find something that has a single HDMI in and single HDMI out, but also send out either a TOSLINK connection or a coax digital audio connection. I've seen a couple but they all tend to be 3 port HDMI switches and therefore cost a lot. Has anyone else run into this and found a good solution?

Same boat as you regarding TV and Receiver...you can just run an RCA cable from PI to your stereo. I haven't had a chance to test this yet though, but fairly certian you can send audio through both outputs, may just require creating an .asoundrc file for ALSA. I'll actually be testing this more later this week.

Let me know how it goes. Much of my dilemma revolves around the fact that I use XBMC and a pandora (internet radio) plugin. I don't want to leave the TV on just to listen to music and it's a pain to manually swap back and forth between analog output and digital. Let me know how it goes though. If you can set things up to output to both then all I'd need to do is change the input on my receiver and that's easy enough to do.

The problem with using the on-board audio out on the Pi, is that it is not very high quality. If you want to really listen to good music you need another digital-to-analogue-converter.

I would like to use my Cambridge DacMagic for that purpose, it will take digital signals via usb, coaxial or optical connections.

So far I haven't had success with getting a clean usb sound source when using Raspbmc, but I came across this thread http://www.raspberrypi.org/phpBB3/viewt ... 35&t=19634 that might hold a couple of interesting clues.

On the hardware side, there are various HDMI audio extractors available, Atlona being but one example:http://www.atlona.com/Atlona-HDMI-Audio ... pport.html

And another one, via Ebay:

I have no idea how well any of these things perform and I do not intend to go that way, both for money reasons, but also to avoid adding more hardware than necessary to the whole system.

Getting digital audio as spdif would be the best, but sound over usb is number 2 and usable for me as well.

I know this is a bit late to this thread, but I feel this is a perfect fit solution

I had forgotten about this thread, but that was indeed the route I took, works like a charm

Not sure about that. I thought I saw one from May 2012 resurrected earlier this week :shock:
