I recently added a Behringer ADA8200 to my UMC1820. All of the new ADA8200 mixer values were zero, and I thought the unit was defective until I found a thread on another site that had this slick trick where you figure out the device number, then using alsamixer send the following which enables all 16 inputs and outputs and sets their levels to 127 then saves the configuration so that it always comes up like that.
When you run alsamixer and hit F6 your audio device will have a number to the left of it. My UMC1820 is number 1, hence the -c 1. This code is for a UMC1820 but might work on other multi-channel audio devices.
Code:
amixer -c 1 cset numid=1 on,on,on,on,on,on,on,on,on,on,on,on,on,on,on,on
amixer -c 1 cset numid=3 127,127,127,127,127,127,127,127,127,127,127,127,127,127,127,127
amixer -c 1 cset numid=9 on,on,on,on,on,on,on,on,on,on,on,on,on,on,on,on
amixer -c 1 cset numid=11 127,127,127,127,127,127,127,127,127,127,127,127,127,127,127,127
amixer -c 1 cset numid=8 0
