Those are exactly the setting I have. Except for one thing that I'm not sure what is: I have the "Set 'OggS' filetype" ticked up.
Just one thing it can be useful cause sometimes you have to deal with 32bit WAV files:
FLAC encoder only supports up to 24bit, so, if you have 32bit WAV's you have to downgrade them to 24bit WAV or AIFF at least, and then convert them to FLAC.
When encoding a WAV or AIFF to FLAC, XLD always keeps the same attributes as the original files (bits and sample rate). A 24bit 48kHz WAV will become a 24bit 48kHz FLAC, etc.
If somebody shares a 32bit-96kHz file and you want to encode it to FLAC, just convert it to 16 or 24 bit and 44.1 or 48kHz WAV or AIFF (your choice), and then encode the result to FLAC.
