[PATCH 0/1] MR6097: dxdiagn: Fill szHardwareId for sound render devices.

[Paul Gofman (＠gofman)]

Somehow the field is not present for sound capture devices, at least on my Win11.

Fixes Tom Clancy's Splinter Cell: Conviction not finding any sound devices and refusing to start.

[PATCH 1/1] dxdiagn: Fill szHardwareId for sound render devices.

[PATCH 1/1] dxdiagn: Fill szHardwareId for sound render devices.

Hi,

It looks like your patch introduced the new failures shown below.
Please investigate and fix them before resubmitting your patch.
If they are not new, fixing them anyway would help a lot. Otherwise
please ask for the known failures list to be updated.

The tests also ran into some preexisting test failures. If you know how
to fix them that would be helpful. See the TestBot job for the details:

The full results can be found at:
