Audio Player SVGs and Validation Errors

I have been working to implement and audio section of my site. Everything was going great until I validated the RSS and found that the audio player/card is full of SVGs that trigger validation errors. I’ve tried editing the rss.hbs to strip them out, but no luck. Has anyone encountered/fixed this? Surely people are successfully distributing audio content and podcasts without issue, so I must be missing something.

I’m using GhostPro online, with the Dawn theme. I searched the podcast-related themes and it looked like those also used SVGs…

Thanks for any guidance you can provide!
