Re: HDMI -> S/PDIF

Because you have to spend 30-40$ on an audio extractor? That, and because it's messy, ugly, and ridiculous. It would annoy me. I have an allergy against wall-warts, cable messes, ugly boxes and blue LEDs. Technology should be invisible, or at least as discreet as possible. Simplicity and minimalism...

Re: HDMI -> S/PDIF

i get your point :) I don't think you do. My point was, and is , that replacing my current HTPC with a Pi2 is not a great idea if it means I will no longer be able to watch films on it, which after all is an important function of a home cinema - regardless of how technically sophisticated it otherw...

Re: HDMI -> S/PDIF

Even a home cinema set-up that can't play lossless audio track is ... suboptimal. Agree? Actually I don't agree - I do not have any video material that has losless audio. Some compression is acceptable, as long as the bitrate is high enough and the full 5.1 soundscape is preserved. It's a wholly di...

Re: HDMI -> S/PDIF

This is only true for HD video. Right. And a home cinema set-up that cannot play HD video is... suboptimal. Agree? Some TVs can forward audio via SPDIF I do not own a television. Some audio systems offer HDMI input and passthrough (to a TV). My audio system has no HDMI input, only S/PDIF optical an...

Re: HDMI -> S/PDIF

So basically, if I understand what's being said
  • 1. Kodi depends on OMXPlayer
    2. OMXPlayer only supports HDMI audio
    3. HDMI audio requires an external, active, "extractor"
Correct?

Re: HDMI -> S/PDIF

Anyone want to buy a new, boxed Pi2, with Flirc case, 16Gb MicroSD and power supply? It seems this device is not for me :D

Re: HDMI -> S/PDIF

One thing you should consider if you are planning to use it for video: omxplayer doesn't support any sound cards (USB or otherwise). You either have to use the low quality analog sound output or find a way to extract the digital sound from HDMI. I don't know what omxplayer is - is that something I ...

Re: HDMI -> S/PDIF

If it works well for you - stick with USB card. I do not know this yet - but that sound card works very well under plain Ubuntu with XBMC on my current "mini" HTPC; never had any issues with DD/DTS pass-through or anything else. HIFIBerry uses I2S bus, so CPU usage should be far less than usb devic...

Re: HDMI -> S/PDIF

Why do you think you need a heatsink or a fan or any external cooling on your RPi? Unless you're living in the middle of a desert in a dwelling (or vehicle) without A/C you won't ever needs a fan or a heatsink. I have no reason whatsoever to assume I would need a heatsink, I just liked the size, lo...

Re: HDMI -> S/PDIF

I use RPi2 + HDD + power supply 24/7 in closed, metal case. No heatsink, no vents. Now it runs @45C. Nice case, and good to know it doesn't get very hot - what's your temperature after watching a 1080p movie though? Also, I already have a case, and a USB sound card, so unless there are specific rea...

Re: HDMI -> S/PDIF

1. Connect your speakers to the TV Set's S/PDIF output. If you look at my post you'll see that I don't use a TV set but a projector, which doesn't have an S/PDIF output. In fact I do not even own a television :o 2. Buy HiFiBerry Digi board - http://www.hifiberry.com/hbdigi/ . This is a neat option,...

Re: HDMI -> S/PDIF

I just found this thread , where it's said that Digital audio is not carried on separate pins. It's encoded along with the video. You wouldn't be able to separate it with a passive adapter. I guess that answers my question. Shame really, I was hoping all that was needed would be the Pi = a minimalis...

Re: HDMI -> S/PDIF

Search for HDMI audio extractor. Thanks gkreidl - I'll take another look, but when searching previously all I could find were active devices, which convert the digital audio into an analog stereo signal, and often have an analog (VGA) video output as well. I'm hoping there is a way to get to the di...

HDMI -> S/PDIF

Hello everyone! I've just got my first two Pi's, both type "2B", and I'm well impressed by the capabilities of these tiny computers :) One of them I'm using as a UPnP audio target (or "renderer" as it's called), and the other I'm planning to use as an XBMC/Kodi box in my home cinema. I'm very much l...
