IPCEvent

[Lurka]

Hello people,
Bluetooth Passthrough gives me IPCEvent warning as in the screenshot on all Wii games for Dolphin builds 8296, 8253, 8221 and 8138.
After that, the game either crashes or stays on black screen. I had to roll-back to build 7982 to get passthrough work again.
My system is Windows 10 1803 with Intel Wireless AC-8260 and UsbDk driver.



I haven't used passthrough for about a month. Yesterday I returned from vacation and Windows happily installed the whole batch of June updates plus the Intel network drivers 20.50.1.1
I reverted Intel drivers to the previous version and uninstalled/reinstalled the UsbDk drivers, but same error.

The latest Dolphin build with passthrough working for me is 7982. Unfortunately, I cannot confirm if later builds were fine before the Windows updates of June, and I don't have debug tools to trace the error.

Thank you and goodbye,
Lurka

I did a little bisection and found the critical version.
The change "BTReal: Fix unsafe reinterpret_casts #7103" in build 8098 seems to be the cause of the issue.
Now the word goes to the developers.

Bye,
Lurka

Please, check if passthrough is working with Dolphin build 8096.
Are you using libusbk installed with Zadig, UsbDk or anything else?

Thank you,

Just tried build 8096.  It works!

Yes i'm using libusbk installed with Zadig 2.3.

So something was changed after build 8096 that messed up BT passthrough on Windows?

I'm using latest master on Windows and bluetooth passthrough is working fine. Zadig driver as well, Windows 10.

Can you try using this build to see if it helps assuming master is still not working for your adapters?

It could also depend on drivers or system bugs. Passthrough with generic USB drivers is an extreme solution recommended when everything else fails. Let's hope the devs look into this when they have time.

The master version 8096 is working, the problem comes up in version 8098.
Where does that link come from? Version 7216 seems to be old and it isn't listed in the master branch downloads.

That build is PR 7216, not 5.0-7216. PRs can be found at https://github.com/dolphin-emu/dolphin/pulls

Yes, passthrough is working again on PR 7216

Many thanks to the always-efficient Dolphin team!
