I've a huge DVD-A collection. It's a excellent audio quality. (not DVD-Video or musicvideo discs)
Can it be possible that VLC supports DVD-Audio discs? (Or at least the advanced resolution LPCM stereo playback at 24bit 192KHz?)
What I do know: DVD-A players only have analog output on the full quality, and digital output is down mixed/down sampled to stereo 44.1KHz or at least 48KHz. (also SACD players).
Yes a bit sad, but record companies seems to be afraid that we can make high quality copies.(lol they probably never found the little program DVD-A explorer, which make multichannel wave files with same bit depth and sample rate, so yes we can
).DVD-A uses different kinda audio codings:
-> 5.1 (Multichannel) is "Meridian Lossless Packing or Packed PCM"(losslessly compressed) and maximum 24bit 96KHz.
-> Advanced Resolution (stereo) is "Linear PCM" (uncompressed) and maximum 24bit 192KHz.

Reason: DVD-A playing on computers is a bit tricky.(because of licenses ?)
I could only do it with my Soundblaster Audigy 2zs (or newer) soundcard software.(MediaSource DVD-A player of Creative).
The soundcard is a 24 bit and supports 192KHz samplerate. Since a few days i downgrade soundcard to Soundblaster Audigy Platinum EX. (it's 24bit and maximum 96KHz samplerate, so it has no DVD-A player software. Playcenter2 instead of Mediasourse). And i only use S/P-dif out, and no analog out. I use my Philips BDP7200 Blu Ray player with analog 5.1 out for 5.1 DVD-A.
I tried to install both creative pci soundcards, but that gives a huge BSOD on windows.(on any pci bus i tried). It's sad that windows can have Creative MediaSource DVD-A player, and Linux has none. So that's why i ask, please let VLC play DVD-A
