line in lost - how to (re)add?

Hey folks

I have a sonos beam and set it yo as 5.1 using my two fives and sub. Great for surround sound when listening to TV and listening to music is good too.

However, in this set up the line in of the fives do not longer exist / work. Appearanrly lost if set up in surround set.

Now I see two options, but I do not like either. Any alternatives?

Option 1) beam and sub. As 3.1 set up. Fives as seperate speakers.

+ I have my jack back 

- I do not have surround sound

Option 2) beam, fives and sub. As 5.1 set up 

+ I have surround sound 

- I have lost my jack

Now obviously I d prefer Option 2 WITH jack.

Is there another way to add this to the beam? (I already use the HDMI for TV sound)? 

Or is there another way to use the jack s that are in the fives?

Curious to learn more.
