@giomasce Looks like this MR introduced various test failures in dsound/tests/capture.c and mmdevapi/tests/capture.c (see, e. g., https://gitlab.winehq.org/wine/wine/-/jobs/174369). I am reproducing those locally. Commit 00211db0d08d60ee9a0e40206bf7cf9b5b88987b (functional change) triggered failures in dsound test (reverting that fixes the failures). The failures in mmdevapi are in newly added test_formats().
