[Bug] BT audio stutter on windows11 with K2 Pro #218

Closed thomaslagies closed 5 months ago

Describe the Bug

Whenever I use the Keychron K2 Pro via Bluetooth on my windows 11 PC, I get audio stutters with my BT Headset. The Keychron is the only device, that causes this. Other bluetooth devices are fine to connect with windows.

I'm running the latest windows update (23H2 Windows 11 Pro - Build 22631.3007) and the latest keychron firmware was flashed (~https://www.keychron.com/pages/firmware-for-k2-version-2~ https://www.keychron.com/blogs/archived/k2-pro-factory-reset-and-firmware-flash) I just flashed not because the keyboard was not working, but because the audio stutter. It seems like it did not change anything.

I don't have these issues on my Mac M1 for example. My Phone also works fine with Headset and Keyboard connected.

@thomaslagies, you mention you have a Keychron K2 Pro, but in the 2nd paragraph of this post, you mentioned you flashed firmware for the Keychron K2 V2, aka, the regular K2. Is that right?

thomaslagies commented 5 months ago

Sorry, I posted the wrong link. https://www.keychron.com/blogs/archived/k2-pro-factory-reset-and-firmware-flash I will update the description.

This seems to have fixed all the stutter! Thanks mate. Also I found the post about audio stutter on the keychron website (via reddit) How could I miss that for almost half a year?!
