[Davide Beatrici (＠davidebeatrici)]

Bug introduced in !600.

```

00dc:trace:alsa:AudioClock_GetPosition (00A53680)->(0022FCD0, 0022FCD8)
00dc:trace:alsa:alsa_get_position frames written: 0, held: 0, state: 0x2, position: 0
render.c:1071: Test failed: GetPosition failed: 00423930
render.c:1072: Test failed: GetPosition returned non-zero pos before being started
render.c:1073: Test failed: GetPosition returned zero pcpos
00dc:trace:alsa:AudioClient_GetService (00A53680)->({f294acfc-3146-4483-a7bf-addca7c260e2}, 0022FCB4)

00dc:trace:alsa:AudioRenderClient_GetBuffer (00A53680)->(24001, 0022FCC0)
```

And then `mmdevapi_test` hangs.
