Hello all. I hope I worded my question coherently enough, but I have a few examples which should help mitigate things.
I have a basic AGPTEK T06S touchscreen chinese digital audio player with a USB type C connection for synching and charging. It is a touch screen running on Android Oreo. The advertisement for it states it has "OTG" but to not use the USB C as a "audio out" source, and to instead use the female 3.5mm buiit into the device.
My goal was to make it work with my Fiio Q5s with a digital connection (usb type c to micro usb cable) and it seems to work perfectly, aside from the battery running out on the DAP within 1 hour when its proported to have a 8 hr life. Then I noticed that that I was able to adjust the volume not just on the Q5s as should be expected, but the volume control also works on the AGPTEK DAP at the same time, almost like a pre-amp. If the DAP is tethered to my Q5s with a cable, shouldnt that mean that its using digitial and not analog?
My confusion comes from being previoulsy obsessed with the whole ipod video > Fiio L9 Cable > Fiio Amp/DAC (ie Andes, Alpen, or whatever from the early 2010's) and it was there I learned that the Fiio L9 cable was only a conduit, and not actually allowing for the external DAC to take over, only to amplify the DAC already built into the ipod. THis was proven by being able to use the click wheel to volume up and down as well as the external amp, meaning that it was only a analog signal being amplified.
Now let me see if I can summaraize this in a nut shell with my limited knowledge of this stuff; if a Android DAP is connected "digitally" via a USB type C to Micro USB, but yet Im still able to affect the volume with the either the Q5s or the DAP independently, does that truly mean Im using the Q5s's DAC, or just as an amplifier?
Example, I have a Vamp Versa DAC AMP made in 2012 made particularly to override the Ipod Classic DAC completely, by plugging the 30 pin to to USB A inout on the Versa itself, and this makes using the volume ability on the ipod to no longer work, and depends completely on the Versa as the volume control.
If Im able to use the volume on both the master and slave device basically at the same time in a preamp/amp type scenerio, does that mean the sources DAC is still being used?
