I understand, I've read your discussion. Once again, many of your discoveries have been discussed (and discovered) before, such as in the thread I linked (including a response from the UAPP dev) and also on XDA. I was merely quoting a tiny snippet. Of course completely up to you if you want to read it.
Because i am not getting native playback from uapp thats what i am referring to in the first place.
For
both Android 9 & 10, LG's default music app is showing
identical behavior for native DSD playback while using inbuilt QuadDAC:
1) DSD logo shown on default music app, proper file recognition is taking place.
2) On the default music app, we are able to change preset equalizers (Pop, Rock, Jazz) during playback,
while hearing perceived sound signature differences with different equalizer presets.
3) During native DSD playback, we are unable to change pitch & speed of the song. It shows "Pitch and speed are unavailable for high resolution audio files"
The above behaviors are confirmed by two G8X users.
Conclusion:
1) I believe on Android 10, native DSD playback runs just fine with no DSD to PCM conversion in the "LG default music app TO QuadDAC TO audio jack" audio chain.
2) USB Audio Player (UAPP) as the name suggests is completely devoted to audio through USB port, mainly targeting use of external DACs & amps. This is where DoP comes into picture. UAPP on Android 10 is unable to send DSD as DoP over USB-C port, hence they are referring "DSD/DoP support is not present in Android 10"
I have Vivo NEX S running on Android 10 and have no issues with native DSD playback using default music player and the inbuilt DAC.
