NTN 16apsk on 103.0W C-band

I don't think it's an osmio4k or image issue but I was wondering if someone has a solution. I'm unable to get audio on this service at 4077V1900-5/6 16apsk on 103.0W. There's no audio on the hdmi cable between the TV and the osmio4k AND there's no audio when trying to play it through vlc or xine or smplayer on Ubuntu 18.04. There's only one audio selection (AC3). I tried a web search with DuckDuckGo but got no useful information. Here's the vlc log output:

-- logger module started --
main: Running vlc with the default interface. Use 'cvlc' to use vlc without interface.
main error: too low audio sample frequency (0)

The easy way is to see what is happening on the transponder. Use dvbsnoop in terminal as it should be pre-installed.

To use dvbsnoop,
(1)Tune the receiver to a transponder you want to scan.
(2) Connect the receiver to a computer terminal.
(3) Enter dvbsnoop -s pidscan in terminal.
(4) Wait for scan to finish,

Looks like in this case, the audio is set to a private stream, for reasons only known to the uplinker. This is why you have no audio. It takes 5 minutes or less to find this information, providing you know how.

It also helps to check your pids and make sure they are being displayed correctly in the receiver. Use Menu--->Information--->Service

Forgive my ignorance, so the Audio PID as it appears makes it a Private stream?
 
I may have told you wrong.
Here is a scan of Heroes on 101w, which shows the same. Let me see if I can find more information about this.
