Hello:

I have a Beomaster 7000 with a phono, CD and tape. I purchased a 7 pin DIN with two RCA jacks to connect to my SONOS connect.

I want to play the system to the line in on the SONOS. It will not play from any of the 7 pin connections. I got it to play from the headphone jack so I know the SONOS line in is working. 
 

There was another post that said to use the tape connection  I tried both tape 1 and 2 with no success.

The line in/out jack doesn’t work either. Possibly because I have only line out, not back in. It appears it may need both to make the loop?

Any help would be appreciated.
