I agree this would be helpful, especially as I only have 2.1 speakers connected and can only provide limited results with this configuration. I would have to replicate everything I did with audio/video files I can actually distribute, and that will take some time. I only had enough time to whip something together with the files I had on hand, and I only have learned enough to do just what I have done so far. I would guess it would take another free weekend day to figure out how to do the rest, and distribute a test file. Also, uncompressed audio at these data rates takes up lots of space!
I was using a 2'40" audio clip (derived from a 24 bit 48 kHz 5.1 DVD-A original source) and the 7.1 24/192 file alone comes in at 702 MiB. I would need to find somewhere to host such a DVD-sized ISO or make a torrent for it or something.
It is interesting, though, and I agree that we should document a test of 7.1 24/192 for completeness. I haven't yet figured out how to create a file with this audio that the PS3 can play, though. As I said, the tool I was using (tsMuxeR) couldn't handle the 7.1 wav, where it did fine on the 5.1. I didn't try a 7.1 24/96 so I'm not sure if it was choking on the number of channels alone, the total bitrate, the 192 kHz sampling frequency or what.
I think there is enough information here to help someone willing to run with it and do some more testing, if someone gets a chance before I can get to it again. The thing that is stopping me right now is creating the .m2ts (or other compatible) test file. I have the audio part nailed, I think.
