Every other song is silent on my VIZIO speaker when played via Google Nest Hub

Plan: Premium

Country: US

Device: Google Nest Hub-> VIZIO Soundbar (V51-H6)

My Question or Issue

Spotify is the default music app on my Google Nest Hub. My Google Nest Hub also has VIZIO soundbar as the default speaker (all of these are configured in my Google Home App on my iPhone with the latest iOS). When I give voice commend to play music, Google Nest Hub will open Spotify and play the song and the sound will be played through my VIZIO speaker. However, every other song is silent. If I change Google Nest Hub's default speaker to Google Nest Hub's speaker, this issue goes away. I tried the crossfade setting and it doesn't solve the problem.

I'm having the exact same issue, very similar setup: Spotify on Nest Mini > Vizio soundbar as default music speaker. Every other song is silent, but manually shipping ahead seems to work just fine.

Anyone have a solution?

Ever find a fix for this? Thanks!

Same issue. Vizio Sound bar V51-H6. Every other song just doesn't play. Or plays for half a second before cutting out while the rest of the google speakers in the group continue to play the song.
