@Careless,
Thank you for reporting.
I can reach out to the team about this and see what is possible — however, I actually cannot reproduce the issue on my macOS system. Are there very other specific steps to reproduce this issue other than what I’ve done below:
- Ensure that HWA is enabled in the browser
- Open up Youtube and start watching video content
- Open new tabs to Amazon
- While YT video plays, browser around amazon, open some links from Amazon in new tabs
- Return to YT to see if audio lag is present
