[PATCH v2 2/2] combase: Execute local server for correct architecture in a WoW64 setup.
by Dmitry Timoshkov 04 Jul '22

04 Jul '22

Based on implementation of create_surrogate_server(). This patch makes 64-bit application work with its own shipped 32-bit COM server.

[PATCH v5 0/3] MR337: winepulse: Return device-specific values for GetMixFormat and GetDevicePeriod
by Claire (＠ClearlyClaire) 04 Jul '22

04 Jul '22

When `GetMixFormat` or `GetDevicePeriod` are used, return values specific to the selected device instead of those of the default one. This is especially useful when the audio devices features less channels than one specifically selected by the application. This patch is part of an attempt to get Sony's DualSense controllers to work with Windows games through Wine. This is not enough by itself, but getting the proper mix format is required for most of those games to correctly use the haptic feedback features of the DualSense (which go through an audio output with 4 audio devices). -- v5: winepulse: Return device-specific values for GetDevicePeriod winepulse: Return device-specific values for GetMixFormat winepulse: Store device-specific format and periods https://gitlab.winehq.org/wine/wine/-/merge_requests/337
