Alexandre Julliard pushed to branch master at wine / wine Commits: fc627e04 by Jon Koops at 2026-05-12T09:48:10+02:00 dsound/tests: Test primary buffer independence across IDirectSound objects. On Windows, two separate DirectSoundCreate calls produce independent primary buffers, each with their own capability flags. Test this by creating a primary buffer with DSBCAPS_CTRL3D on one IDirectSound object, then creating a primary buffer with DSBCAPS_CTRLVOLUME on another, and verifying that each buffer retains its own flags and that GetVolume succeeds on the second.

On Windows, each DirectSoundCreate call returns an IDirectSound object with its own independent primary buffer. Wine reuses a single DirectSoundDevice for all IDirectSound objects targeting the same audio endpoint, causing them to share a primary buffer. This breaks games that use multiple IDirectSound objects with different primary buffer flags. The device reuse was introduced in 2005 (commit a2f1fd3aca4) when dsound talked directly to waveOut, where opening the same hardware device twice would have caused conflicts. In 2011 (commit e786998daff) dsound was reimplemented on WASAPI, but the reuse was carried forward. Since Wine's dsound already uses WASAPI shared mode, which is designed for multiple audio clients on the same endpoint, the reuse is no longer necessary. Remove the device reuse lookup so that each DirectSoundCreate call creates a fresh DirectSoundDevice.
