Hmm, never thought about it that way but it makes sense. Unless I'm missing something, you'd need to decode the signal to attenuate the amplitude which defeats the purpose of using an external DAC. Unless there's a way to pass the volume attenuation info along without interfering with the digital audio signal. LOL at True Hacker®️

Nope. But, again, if it does then you aren’t passing PURE AUDIO data to your DAC and are therefore obviating the whole point of paying big bucks for it—i.e. to get the purest best conversion from digital to analog audio. I’ve been very happy with my Logitch 5.1 DTS DAC/audio system, but yeah, I have to use the physical knob to change the volume. It’s certainly conceivable that a side channel could control the DACs volume, but I don’t know of any that implement that; Let me know if there are any and I may buy one! 😄 Actually I could implement a computer to IR “remote control” to change the volume, but it’s not worth it to me... yet. I guess I’m not a True Hacker®️ (willing to spend weeks programming, to save minutes of effort) anymore. 😋

I'm using the volume knob on my headphone amp which also serve as a pre-amp so it's not the biggest deal, but it would be great if I could control the volume via keyboard. Do you know how to make that work with the UD-501? It works with some smaller DACs.
