converted SACD no audio - sample rate problem?

[unfrostedpoptart]

Hi all.

I have a bunch of dff files from RIPs of my SACDs. I can play these fine in JRiver, but I'm converting them to 5.1 FLACs to be more portable and play in any program - including vlc. When I convert to FLAC in JRiver, the output files are 352,800 Hz sample rate, 24-bit depth, and 6 channels. I can hit play and it looks like it's playing but there's no sound. And, if I select the Audio menu, the Audio Device option is grayed out. The file plays fine in JRiver. What's going on? I didn't see any obvious options to change in vlc.

Here's what shows up in the messages window when I put the file into the playlist:

VLC currently has a safety limit of 192 kHz. You will need to modify the source code and recompile.

Thanks for the reply. I just tracked down the info for compiling vlc on Mac and doesn't look like it's worth all the time it would take me to set up even though I have parts of Xcode already installed.

Any chance this will be fixed/configurable in the upcoming 2.1?

Sure thing.
