It’s not clear to me what you mean by ‘gets skipped’.
My guess is, since the information coming in to the Amp is ‘denser’ or ‘fatter’ in bandwidth than normal streaming, you could be experiencing just enough wifi interference to cause some interruption. If it was happening on all streams, I would suggest duplicate IP addresses, but you seem to be saying it’s only on the TV input to the Amp.
Have you submitted a system diagnostic within 10 minutes of experiencing this problem, and called Sonos Support to discuss it? Don’t post the resulting diagnostic number here, they get sensitive about GDPR.
There may be information included in the diagnostic that will help Sonos pinpoint the issue and help you find a solution.
When you speak directly to the Support staff, they have tools at their disposal that will allow them to give you advice specific to your network and Sonos system.
