the ambient sounds (eg. sound of fire pit in seattle cave, water in lima, ...) aren't looped. they are only played once.
Error still exists in build Sep16 Win32 and exists in all earlier builds afaik.

I have found the looping information. I give offsets from the begining of the SO block. At 0x26 there is the loop start At 0x2A there is the loop end If the loop end is 0, the sound is not meant to be looped. Those are offsets from the begining of the sound (which starts at 0x36).

Looping of full sounds is now supported. Partial looping is still unimplemented, and these sounds will loop from beginning to end instead of only looping the specified area of the sample (see Fixme in scumm/sound.cpp)

update: loop end and loop start are not in bytes, but in "ticks". 1 tick = 1 byte at 11KHz, 1 tick = 2 bytes at 22KHz. wave size is still in bytes.

fingolfin, the first example of partial sfx looping seems to be the plane noise onboard plane. I attached save game in airport, should hear a slight pop at end of each loop.

Looping is not yet implemented, simply because we have not yet figured out how to determine whether to loop a sound or not.
