it is a bug of rewrite when wine's mmdev does not check whether the device can
be open more then once using shared mode and exclusive mode

e.g spdif with ac3 passthrough cannot be open twice

The main problem of current implementation is

dxdiag cannot test sound card

which is normal in win 7 but abnormal in xp
