LSL6CD from GOG: compression causes issues on 2.1.0

[bluddy]

When compressing the RESOURCE.AUD for LSL6CD (bought from GOG) using scummvm-tools, upon startup, ScummVM 2.1.0 tells me that it detected corrupted files and the console spits out a long list of what it considers to be missing audio files inside RESOURCE.AUD. Other than that, the game starts properly and speech plays.

I've never used scummvm-tools but according to the readme it's not expected to work. I'm assuming the GOG LSL6 CD is the high resolution version, which is SCI32.

compress_sci
    Used to compress Sierra resource.aud/.sfx and AUDIO001.002
    audio files with MP3, Vorbis or FLAC. This tool is NOT
    compatible with the newer SCI32 games yet.

Oh I missed the fact that LSL6CD high-res is SCI2. Sorry.

It's confusing!
