When tracking all my 24bit wavs in cdwav I never checked the "use alt. 24 bit format" box.

I'm now unable to encode anything.

Would upgrading my version which 1.7.1 etree edition help with this? The SB box in flac frontend in unchecked.
One solution is to re open each wav in cdwav and re save with the box checked, but I thought I read on the board that a newer flac version might do it.
thanks, ts
