streambar and optical output from TV

I have a non-ARC TV but it does have an optical audio output port. I connected the HDMI cable from TV to streambar and also connected the optical cable from TV to streambar. This works fine with Roku streaming various channels. However, I also have an HDMI cable going from my cable box to another HDMI port on my TV. When I select the TV HDMI source, I get the audio on the TV speakers rather than the streambar. Since I have the optical cable connected, shouldn't the TV audio also go to the streambar, rather than TV speakers?
