A keyboard with a volume control dial has been observed to have an anomaly where it cannot adjust the system volume to 0. Visually, it appears that when the volume is adjusted to 0, it automatically returns to a position around 12% afterwards. Several tests have been conducted to isolate the issue: 1. The keyboard was connected to another computer running Windows 10, and it functioned normally, allowing for volume adjustments to 0. 2. A VMware virtual machine running Windows 10 was created on a Windows 11 host, and the virtual machine's volume control functioned normally. 3. The volume slider was adjusted manually using a mouse on the Windows 11 host, and it was able to be adjusted to 0. This presents a puzzling situation, as the hardware appears to be functioning correctly. An unknown issue or configuration problem may be responsible for this behavior. It would be helpful to gather feedback from others who may have experienced similar issues or provide guidance on the most reasonable approach to troubleshoot and resolve this problem.
