[PATCH 2/6] winealsa: Pass EDataFlow to alsa_try_open().
by Huw Davies Feb. 15, 2022

Feb. 15, 2022

Part of the motivation for this patch is to eliminate variables named "stream", in order to avoid confusion with audio streams. It also avoids cases where both "flow" and "stream" are passed to the same function, conveying the same information.

[PATCH v2 1/5] winepulse.drv: Expose audio devices to the application.
by Gabriel Ivăncescu Feb. 15, 2022

Feb. 15, 2022

This exposes the actual devices (and virtual sinks/sources) as reported by PulseAudio to an application, allowing it to select the devices itself and, for example, record from (or render to) two devices at the same time. The "PulseAudio" device (which is movable) is still the default, as before, with the same GUID to preserve compatibility with existing setups.

[PATCH v2 0/3] Fix for BZ52048
by Eric Pouech Feb. 15, 2022

Feb. 15, 2022

As described in bugzilla ticket, when calling CreateProcess: - with "default" console inheritance (no CREATE_NEW_CONSOLE nor DETACHED_PROCESS flags), - when parent is not attached to a console - and when the child's subsystem is CUI , native behaves as if CREATE_NEW_CONSOLE was passed. builtin doesn't... this serie: - adds a test case for showing the CUI/GUI discrepancies - fixes kernelbase accordingly - but also requires to fix all usage of CreateProcess in Wine Code that would now generate the creation of a console + one patch of wow64 redirection (only for CUI executables) + when looking to the other usage of CreateProcess, I only convinced myself to adapt one of them V1 => V2: - don't mess up with the number of patches in the serie - no longer modify makedep for creating cui vs gui test executable, but copy current *_test.exe executable and adapt its subsystem to the need Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=52048 A+ --- Eric Pouech (3): dlls/kernel32/tests: add some console tests about creating cui vs gui processes programs: don't recreate a console when redirecting a program to wow64 dlls/kernelbase: handle corner case in CreateProcess dlls/kernel32/tests/console.c | 85 +++++++++++++++++++++++++++++++++++ dlls/kernelbase/process.c | 6 ++- programs/services/services.c | 2 +- programs/uninstaller/main.c | 6 ++- programs/winedbg/winedbg.c | 3 +- programs/wusa/main.c | 3 +- 6 files changed, 99 insertions(+), 6 deletions(-)
