The sampling frequency changes automatically.

[D_IMAN]

I noticed that on my Bluetooth headphones the sample rate changes automatically.

If I take them out of the case, the frequency is 44100Hz

If I turn off and on the Bluetooth module or restart the laptop, the frequency becomes 48000Hz.

Why is this happening?

And how do I fix the frequency I need?

Headphone model BGVP Q2s

Notebook model N7400PC (X7400PC)

Since I can't understand Russian, check the pictures you provided, could you please explain the following differences?

Regarding the following description:
"If I take them out of the case, the frequency is 44100Hz
If I turn off and on the Bluetooth module or restart the laptop, the frequency becomes 48000Hz."

Could you please provide me a video of how to do this part?
Thank you.

You got it right!

If you take them out of the case, or simply turn them on, the frequency is 44100

If you turn off \ turn on Bluetooth, or preload the laptop, the frequency. 48000

After confirmation, the sample rate value is determined by the Microsoft operating system based on the specifications/values detected by the system at that time. Therefore, the situation you have reported is precisely this process where the system detects and confirms the connected device and provides it with the necessary value. This is considered a normal phenomenon.
