hi fellow UP5 owners, I just want to share my finding (pardon me if this was already shared) regarding my issue with delayed audio start after around 10 seconds of no active sound when using in wired DAC/amp setup
I managed to resolve it by doing the following:
1) go to path ---- C:\Program Files\Shanling\USB Audio Device Driver\W10_x64
2) open the file ShanlingUsbAudioCpl.xml (disable read-only and open your text editor as administrator)
3) Find (ctrl+f) "PageOptions"
3) change <Visibility> setting from "Hidden" to "Visible"
4) save the file (if cannot save in same folder even with admin rights just save in other location then replace the file)
5) open Task Manager
6) go to Details tab
7) find ShanlingUsbAudioCpl.exe then right click and "End Process Tree"
8) go back to path ---- C:\Program Files\Shanling\USB Audio Device Driver\W10_x64
9) find ShanlingUsbAudioCpl.exe then right click and "Run as administrator"
10) go to tab "Options"
11) change the Streaming from "On when Needed" to "Always On"
12) close the application window

edit: by the way this was done on my Windows 10 laptop. I'm not sure whether this is happening in macOS as well or not and how to resolve it for macOS but I definitely experience this on my Apple Music on iOS (iPhone X) and Tidal on Android 10 (Huawei Nova 5T) too. Maybe
@Shanling can request the eng/dev team to include this option in the iOS and Android companion app in the next update?
