$ alsamixer v1.2.2  

HDSPconf 1.4 from alsa-tools-gui  

i dont know why iis called DDS Sample Offset

but it should be a slider similar to HDSPmixer 

DDS "Sample Offsett" is similar to a PLL with a more aggressive rejection of the external clock signal. IF external clock coming from s/pdif is better vs. RME DDS 200pico second jitter clock, worsens the clock. like a blend control: 0% preference for internal DDS clock = 100% preference for external clock, 100% preference for internal DDS clock = 0% preference for external clock. at: [100% DDS](https://www.youtube.com/watch?v=zJLw2SF_L-g&t=27s) DDS is the Truck, still follows ext.clock, as a recommendation, Not like an [Orchestra](https://www.youtube.com/watch?v=HqCIYWZ5b7k&t=0s)%5BDirector%5D(https://...) 0% DDS, ext.clock becomes like a Whip, internal like a Horse / Slave / [Circus Lion](https://www.youtube.com/watch?v=zJLw2SF_L-g&t=105s) DDS is the Lion.
