[Flac] problems with 24 bit recording (Edirol R-09 > flac > audacity)

[Dat Head]

Roland Edirol R-09 recording at 24/44 (not sure of R-09 f/w version)

when going from wav to flac using flac v1.2.1 you get:
 WARNING: legacy WAVE file has format type 1 but bits-per-sample=24
flac s/w is probably right here and Edirol is not setting bit properly,
anyway to twiddle it?)

then if you use audacity 1.3.2beta to edit the flac file it shows up
all screwed up - don't panic (like I did!), you can just go from flac
to wav again then edit the wav.  not sure if this is due to the "type 1"
thing or not?

anybody have any ideas?
