In the first week of July 2022, there will be a firmware upgrade for U2 Mini to fix a USB low volume issue from some particular (not all) USB DAC.
If you’re using USB output from U2 Mini, there is a small chance that after doing the firmware upgrade, the DAC output volume will be increased even without changing the Lumin volume or volume control enable/disable setting.
This issue does not affect U1 / U1 Mini or any other Lumin model. They will not receive the same firmware upgrade.
