I got this amplifier (SMSL A100) to power my Edifiers for my desktop, however the firmware seems to have an annoying bug:

When using it as a USB DAC, pressing mute on my keyboard or turning Windows volume down to 0% will actually toggle the "mute" function on the amplifier itself. This would be fine, but unmuting windows doesn't unmute the amp. I have to physically press the mute button on the amp itself to unmute it.

I'm not very familiar with how USB audio works with windows. Is there any way of preventing Windows from sending a "mute" signal to the amp when the sound is at 0%?
