1) Do the needful — check that you have flac in your transcode codecs, and that you’ve added the full path to wavstreamer and the flac decoder binary in the transcode script. Run the script by hand to make sure it will output data, and cat that into a file and see if it is a valid wav file.
I didn’t know it was needful :-). The Unslung version ran out of the box, if I remember correctly. Anyway, I appreciate you patience. This part is SOLVED.
2) Check permissions. If it scanned the rest but not the new ones, it’s likely permissions.
I thought myself it was a permissions problem, but all permissions are the same. Any other ideas?
