I have a DFR arriving tomorrow and will be using with UAPP and a Motorola Moto G 6 Android phone. I have had this set up before but cannot remember the optimum volume settings, could someone please let me know what's best.
Many thanks!
I don't have the same phone as you, but I'm assuming it's more or less the same. The good thing is that none of these adjustments are irreversible, so if I were you I'd just play around with settings until it seems best for your needs. There are only three settings that matter to me, the rest just seem like personal preference...
Under Settings >> Volume:
1) USB Volume control = Hardware volume control (my take is this allows UAPP to control the DFR's volume directly, rather than decreasing bitrate through software)
2) Use volume rocker buttons = On (if this is off, you can't adjust the volume when the screen is locked or UAPP is otherwise in the background)
3) Next/prev track = Off (I want to be able to use my phone's rocker buttons to adjust the volume (see 2, above); the On position will allow you to change tracks instead)
Also, with the main volume slider at the middle position, I like to keep the hardware volume just slightly higher than my normal listening level. Otherwise it seems like volume is either too low or increments between volume steps is too great.)
I also keep crossfeed on because it seems like soundstage depth is increased slightly. Of course, this could just be me imagining things. The effect seems pretty subtle.
My one small complaint about UAPP is that they update it so frequently and it seems like often one thing is broken as they fix another. The positive aspect is that they update the app so frequently that it's not broken for very long before it's fixed again.
