Hello

I have a problem with reading sound devices. When I'm trying to change audio driver, I'm getting this error:

Failed to read sound
Devices your audio driver might not support this feature.

I'm using 2 sound devices notebook's sound devices (it's calls 2-High Definition Sound Device) and headphones and all drivers has installed and updated.
I'm using OC Windows 10.

Details in screenshots:

Can you please send me the log file? It should print a more detailed error message to that file.

latest.log

Can you please send me the log file? It should print a more detailed error message to that file.

I have the exact same problem.

Maybe the error is caused by system language (me and the thread starter both have Russian set as the language)?

Log attached:

latest.log

Here's the error message:

OK after testing more Id realized that when my Bluetooth headphone and only my Bluetooth headphone connect it stops working, It works with my JBL Bluetooth speaker but with my Airpods Max it doesn't work

edit: after trying to edit setting no matter what as long as my headphones are connected it won't work I think its has something to due with it have hand free drivers while my speaker just shows up as a speaker

It looks like a charset problem. From the logs, it just seems like the lwjgl is doing something wrong. It tried to decode alcGetString()'s return value, but then the java.nio.charset.MalformedInputException just got thrown.
So it's not your audio devices' fault I guess.
Maybe I'll try to set my system language to EN and see if things work.

nope, the system language isn't the problem here. maybe alcGetString() some devices will just return weird value?

I had the same issue, and I renamed the audio device from "スピーカー" to "Speaker". It worked for me.
I think this issue is caused by audio device names that contain non-ASCII characters.
