Topic: Pianoteq audio panel crashed with Realtek ASIO driver

I am in the process of setting up a new Win 10 22H2 PC and installing Pianoteq 8.4.3. So far so good.
I installed the official Realtek ASIO Driver using these instructions: https://www.baumannmusic.com/2021/the-o...novo-asus/
When I open the Pianoteq audio devices dialogue I see two Realtek entries. The first one is a Logitech Speaker connected to the analogue 3.5mm out of the motherboard. The second is the Toslink out of the motherboard that goes to the speaker I have by the Kawai.
When both audio devices are selected and when I click test, I get sound from the analogue speaker only. Nothing via Toslink. I can deselect device #2. When I try to deselect device #1, Pianoteq crashed with the attached error message.
I would prefer to use the official Realtek ASIO drivers vs. asio4all. Has anyone else hit this issue and found a solution?

Error message:
---------------------------
Pianoteq v8.4.3/20250618 CRASH (ctrl-C to copy)
---------------------------
SEH exception caught, code=c0000005
Ctx{7e0f2039=140000000,113c83c,113cad4,1145432,113b689,,,}
---------------------------
OK

Use this one by Steinberg (creator of ASIO Protocol) Generic for everyone: Steinberg built-in ASIO Driver 1.0.9 (December 2024) : https://helpcenter.steinberg.de/hc/en-u...n-download

Re: Pianoteq audio panel crashed with Realtek ASIO driver

Realtek ASIO, ASIO4All and the Steinberg Generic Low Latency ASIO driver are all 'aggregate' drivers that 'wrap' non-ASIO audio drivers and present them as ASIO to audio applications. They are all more or less problematic vs. a native ASIO driver provided by a reputable audio interface manufacturer. If they happen to work seamlessly right out of the box on a given system with a given application and audio interface hardware, great, but I woud not waste time trying to get any of them working properly if that's not the case.

Steinberg built-in ASIO Driver ITS NOT Generic Low Latency ASIO Driver

Try and see.

I get 3x the latency with the Steinberg one.

Sorry I thought your use of "built-in" was just shorthand for the same old Generic Low Latency driver; I see now that the  "built-in" driver is purported to be new and improved and supercedes the old one. But it's still an "aggregator" that wraps non-ASIO drivers and could have problematic interoperability with some applications for the same reason.
