Can't play audio files on Nvidia Shield

[letang2 1]

I'm trying to play audio files (in this case an MP3, but I've also tried it with M4B and AAC) on my NVIDIA Shield; however, they won't play when my Shield is connected to a different network than my media server. The problem does not occur when accessing Emby through my web browser or the Emby app on my phone. It also never occurs when playing video files, regardless of what device or what network I am playing them on.

NOTES:

Media Server (running Win10, with Emby Server 4.7.5) is connected to my home network/router.
NVIDIA Shield (running Shield Experience 9.1, with Emby app 2.0.77g) is connected to a different network/router.

STEPS TAKEN IN THE ENCLOSED LOGFILE:

-Opened Emby on NVIDIA Shield; tried to play the song "Blinding Lights." Playback is stuck at on 0:00 on my Shield, with no sound coming out; however, according to my server's dashboard, the song was playing. See the enclosed pictures for what the Shield and the server dashboard look like.
-At this point I connected my NVIDIA Shield to my home network/router.
-Re-opened Emby on NVIDIA Shield; again tried to play song "Blinding Lights." Same result as before, as seen in the images.
-In Emby app on NVIDIA Shield, clicked "Switch Server" then re-selected the same server. Tried to play the same song again. This time, the song works just fine.

I hope I've provided enough information; please let me know if I need to give more.

EDIT: finally solved this myself 15 minutes after posting it...after waiting 2-3 months to post it to these forums. Go figure. Apparently my Emby server config was pointed at my old security certificate rather than my new one. Not sure why this only affected audio files, and not video files, but it seems to be resolved. Mods, feel free to delete/close/whatever.

Hi.  Glad you figured it out.

I'm having same problem on Nvidia Shield: no audio plays on Music. Bouncing simulated spectrum bars indicate that it thinks something is playing, but no sound. The video stuff seems OK (although very low volume). Music works OK when using Roku on TV, and when played directly on the server. End time of all pieces indicates -5:00. I checked that the premier key was correct. Tried removing the Emby app from the Shield and reinstalling - this didn't help. Tried switching servers then selecting the same one - this didn't help. I don't know what the security certificate (referenced above) is, or how to reset it.

Edit: BTW, the server and the Shield are both on the same home network.

Also: I just noticed that the end time on the Roku is also wrong:  -4:32 (negative number).

Also:  Android Shield TV SW version:  9.2.4(33.2.0.400). Not sure when this was installed, but music audio used to work. Emby is the latest version on both the Shield and the server.

Hi.  Are you sure that is the end time and not the remaining time?  Exactly where are you seeing that?

The negative time is on the right side of the progress bar at the bottom. Yes - this apparently shows  the time remaining and it is OK. In any case, on the Shield the 3 animated bars at the top representing the spectrum (or changing level or something) to indicate that the selection is playing are moving up and down, but the progress bar is not moving, or even showing up at the beginning. The Roku is working OK.
