Summary
GMail's audio attachments started failing to play with Google Chrome 91.0.4472.77. The console shows:
Refused to load media from 'https://mail.google.com/mail/u/...' because it violates the following Content Security Policy directive: "media-src https://*.googlevideo.com/videoplayback/".
Seems that GMail isn't following the newly activated CSPs. Until Google fixes it, this simple extension resolves the problem.
Safety
Risk impact
GPlayer is risky to use as it requires a number of sensitive permissions that can potentially harm your browser and steal your data. Exercise caution when installing this add-on. Review carefully before installing. We recommend that you only install GPlayer if you trust the publisher.
Risk likelihood
GPlayer has earned a fairly good reputation and likely can be trusted.
