Matt,
Just to clarify a few things.
1) I got MJ to play back 24-bit files, but only if I select 'settings> options> playback> bitdepth = 16-bits' !! (selecting 'Source bitdepth' or '24-bits' will return the error I mentioned earlier).
2) I played with Media Editor and found that it will fail to load a 24-bit file most of the time. It goes through the load process, but then displays garbage (actually a flat line instead of the waveform).
3) If I prime Media Editor by loading a 16-bit file first. Then close that file and open the 24-bit file next, it (mostly) loads and displays properly, but it's response isn't consistent.
4) The volume control on MJ is stuck at Max in Win2k (this was mentioned by another user in an earlier post). The VC was stuck when I had an Echo Layla in the box with beta Win2k drivers. Now I've replaced that soundcard with an Echo Mia with release drivers (and complete re-install of Win2K) and the VC is still stuck.
5) The 24 bit test files I'm using include one that I loaded into Media Editor and saved from there. So that *should* eliminate the possibility of any nasties in the file format.
6) I've turned off Windows system sounds to prevent the OS from squirting any non-standard sampling rates (ie, 11khz, 8-bit, mono system sounds) into the card. (These can cause a card to stop accepting alternative bit rates/depths, or make it play back at reduced speed)
None of the above is a show stopper for me. Mostly I only want to play 24-bits when I'm still working on a master copy from a vinyl transcription, getting rid of the clicks'n'pops. It's just one of those things that 'It Would be Nice to be Able to Do (tm)'
Thanks again for your support, it's great to see a piece of software develop like this.
