Re: Hardware DTS decoding

https://github.com/xbianonpi/xbian/issues/172 From there it seems like someone is working on a workaround for that specific issue (dual audio output via hdmi and 3.5mm analog at once) that doesn't involve either ALSA or PulseAudio. In OMXAudio.cpp, the number of output channels is hardcoded to 2 (l...

Re: Hardware DTS decoding

https://github.com/huceke/omxplayer/blo ... MRemap.cpp

It looks like OMXPlayer already checks to see what the output capabilities are. I don't think it hardcodes 2.0 over there. It could be that the check isn't done properly or something, but really this is speculation.

Re: Hardware DTS decoding

So according to this: http://forum.stmlabs.com/showthread.php?pid=35504 right now, Multichannel PCM is not enabled (as I suspected). I'm not sure what the audio patch would entail - I would try to tackle it, even though I'd probably get a bit lost - but am also surprised more people didn't ask for o...

Re: Hardware DTS decoding

Thanks for the reply, but as I say, bitstreaming (what you just described) works just fine. I want to know if on-board decoding to PCM is forced to downmix and output 2.0 or not, because whatever the speaker configuration I specify in the settings don't seem to matter - it is always downmixed. This...

Re: Hardware DTS decoding

I'm sorry; I'm not sure if I understood correctly. Is downmixing to 2.0 PCM from multichannel DTS *forced* when not bitstreaming? Can't just output the original channels (5.1, 7.1, you name it) in PCM? Because this has been my experience, with a 7.1 receiver, and I'm not sure what to make of it.

OpenELEC/XBMC and 7.1 AAC

Hey all, So it appears that OpenELEC, as of now, cannot handle 7.1 AAC files (compressed from DTS MA tracks). What I get, consistently, is silence. I'm not sure if this is something the Pi can't handle, something the XBMC can't handle, an MPEG-LA licensing issue, or an encoding issue. All references...

Re: Is it dead, Jim?

Just got off the phone with Farnell Export. They do have stock reserved for replacement, so they'll be shipping me a new one via UPS. No word on whether I need to send back the faulty one.

Thanks for the help everyone!

I realize that what I'm about to say sounds like a real "duh" statement, but I was having these issues at first until I realized that I hadn't seated my hdmi cable all the way for fear of breaking something. So are you certain your hdmi cable is fully inserted into the pi? I'm seating it the same w...

Re: Is it dead, Jim?

I do think the original cable is junk though; it won,t work with my laptop anymore. I guess it,s possible that all my cables are somehow faulty, but that would be odd considering that theyd seem to be working with different hardware (the exception being the cable I normally use, which is toast.)

Re: Is it dead, Jim?

Just tried jiggering again with a different cable. If I get it in position *just right* it'll show something, as long as I hold it down. As soon as I stop applying force, the picture goes to green and then black.
soo...anybody have experience RMAing these things?

Some more details - all I have plugged into USB is the dongle for my Lenovo Wireless keyboard remote. The card is an ADATA 8GB that I've had no trouble with. I'm using build r11318 of OpenELEC, which was working fine less than 24 hours ago.

Freaking out a bit. Video output from the Pi via HDMI is all screwy. With my regular cable, I got no video at all.

Re: OpenELEC Testbuilds

Build 11312 doesn't load, hangs for 30 secs before complaining that /dev/mmcblk0p1 (e.g. the SYSTEM partition) cannot be read. Tried recopying SYSTEM from that build - nothing. It worked again when I went back to r11298. I'm sure we're way past this by now buildwise but just a head's up all the same.

One problem I'm having is, even though I set resolution to 1280x720 in system settings, it keeps starting up at 1280x768. While this is reflected correctly in the status, under system settings it still says 1280x720, as I had left it earlier. I need to change it to some other res and then back to 1...
