WAVE_Open called >10 times with varying parameters

I would appreciate any hint as to how DSOUND_PrimaryOpen leads to a
loop where some code -- where does it come from? -- tries and opens
each audio driver in turn with varying format parameters
8/16 bits, 0 or 3 channels, 11025/22050/41000/48000/96000Hz
somehow derived from the original parameters to SetFormat.

The attached file shows the parameters that winmm:WAVE_Open logged.
In between, error lines from gsm show that this driver (that I did not
compile in) was accessed plenty of times as well (only 1 shown).

Note that The Westerner needs a native amstream (and hence quartz, but
not devenum), as well as l3codecx.ax (from DirectX9) to work. Could
this loop come from there? Or is it the "mapper" in action?
