Thank you for the confirmation. Let's check through the classic sound settings menu. Let's disable Hands-free instead.
Press the Windows Key + R to open the Run dialog box.
Type mmsys.cpl and press Enter.
In the Playback tab, locate your Galaxy Buds 3.
You may see two entries:
Stereo (high-quality audio).
Hands-Free (low-quality telephony profile).
Right-click on the Hands-Free option (e.g., "Galaxy Buds 3 Hands-Free AG Audio")
and select Disable.
Click Apply, then OK.
Then, please Switch to the Recording tab.
Locate the Galaxy Buds 3 Hands-Free microphone.
Right-click on it and select Disable.
Click Apply, then OK.
Please let me know if you have any more questions, I'll do my best to respond as soon as possible.
