TV Shows as IEC958 no audio over HDMI

Trying to get audio to work on a side screen thats a sony TV XR-55A80L. Worked perfectly fine in windows never had an issue, since moving to bazzite there is no audio.

Noticed it shows as IEC958 in settings without any HDMI option Does anyone know what could be the issue?
