If you open an AVI in VirtualDub, you can choose File - File Information. In the Audio Decompression section, it often lists something like :
Unknown codec (tag2000)
I have seen a variety of these tab types (for instance tag0055, or Tag 0161).
Is there a list somewhere where I can find the type of audio each one of these tags refers to? If not, can we start one here?
Tag2000 - AC3
Tag0161 - Divx3 audio codec included in 3.11a Alpha codec
Tag0055 - ????????
Thanks,
Rooster

The tags you refer to are Windows constants defined in MMREG.H in the Platform SDK. All of these start with "WAVE_FORMAT_[something or other]"
The Platform SDK can be freely downloaded from Microsoft, but it's huge. I would have preferred to give you a Web link to an actual MMREG.H file somewhere on the net, but all I could find on Google were old versions. So, for everyone's convenience I might as well just go ahead and list all of the known WAVE formats here:

Note that some formats you may encounter are not included in this list, possibly because they are proprietary, or specified in a different .H file for some specific use. (For instance, I happen to know that 0x0161 is Windows Media Audio Version 2. The DivX ;-) Audio codec you mentioned is an illegal hack of Microsoft's codec.)
