I believe SONOS could have a very popular item by making a SONOS transmitter for TVs.
In simple terms take the soundbar electronics and toslink interface and package this as a SONOS tv transmitter. Use a USB interconnect for the power supply and have a nice small package that could fit behind wall mounted TVs.
I would like to use the SONOS speakers for my TV but do not wish to have a SONOS soundbar in the mix.
This would seem to offer another way for SONOS to bring users to the family of products.
If there is something that already does this please let me know.
