I want a Lossless audio codec to show up in this window:
Is it possible to make FLAC or something else show up there?

For it to show up there, you would need to have an ACM-based flac encoder installed. AFAIK, while there is a Directshow one, I don't see one for ACM. Someone would have to program that.

Hello,
sorry i have one question. Do you feed virtualdub also with lossless audio?

As Cornucopia said, there is no [ viable ] ACM .dll for a lossless audio format — even though the AVI container does support variable-bitrate audio.
And if there was, it should be for ALAC, MPEG4-ALS, even WMA Lossless. Flac has always been a mess and IMHO would not be worth the effort.

"<No compression (PCM)>" is lossless.
Are you using it for some kind of intermediate? IMHO PCM is good enough for that - even uncompressed audio is often small enough. As the others said there doesn't really seem to be a common lossless codec for AVI. It is possible to use FLAC with the "External Encoders" feature (preferably with non-avi output, e.g. mkv) but that is more complicated than just selecting a codec in the ACM codec selection.
More info in VirtualDub help (F1) via Processing->Using external encoders and here.
(All that said: there are FLAC ACM versions. I haven't tested them, though. VBR in AVI is not a problem per se, only variable frame length.)
