Set Shuffle on Sonos not possible when current source does not support it

Hi There,

I have a pretty straight forward problem / question.
Let’s say my current source on my Sonos is Tunein and I want an automation to start playing a playlist on Spotify in shuffle mode. When the source is already Spotify this is no problem. I just call set_shuffle before playing the desired playlist. But since Tunein does not support Shuffle the command is ignored and the playlist just starts playing with whatever setting Shuffle was set to before switching to Tunein. Is there any way around this problem?
