ffmpeg does not support seeking on flac even when muxed into mkv or avi, so that is useless in Kdenlive. Try it ffplay.

I do not plan to make a FLAC producer in MLT. FLAC in mkv or mov does not work either. This will have to wait until there is another mega-producer based on libquicktime, gstreamer, xine, or vlc. The only one I can see coming anytime soon is gstreamer. I can add an audio transcode preset.

I noticed there is a WAV transcode preset, but it is coercing output to 48 KHz.

I've had similar problems with WAV a few weeks ago, but now they are gone. I'll close this bug, is this okay?

About the preset, I think 48 kHz is fine, also since source audio is usually WAV anyway and does not need to be transcoded.

Tried again (exported the FLAC file from audacity as 24-bit). Worked.
