It still isn't a good idea.

why?

With digital volume control it is better to use as high a setting as possible in general. If you can lower the gain elsewhere in the system it should give better results. To be honest I am surprised you can hear anything with the amp set to a volume of 1. Are you just using the amp connected to speakers or something else?
