Help with broken audio for Ch 9 Australia. Need plugin?

[syd_reddit]

Hi - I'm just starting out using Jellyfin for IPTV streams in Australia.
Have installed and running fine on macOS using this for m3u8
https://i.mjh.nz/au/Melbourne/raw-tv.m3u8

All the channels are working fine except for Channel 9 family of stations.
There is no audio and the image is blocky.

Just wondering if there's a plugin I need to decode theses streams?

Thanks for your assistance.

Here's an update.

If I use Jellyfin mobile on iPadOS, the channels play fine, with audio and good image.
So it looks like there's a bug in the Apple Silicon macOS version of Jellyfin that's breaking the playback
