There was a solution that I came across in YouTube that did the trick for me without the extra cable and Anynet enabled.

Connection --> HTS connected to TV via HDMI (ARC), Cable/Satellite Box connected to the TV via HDMI.

Instead of connecting the cable/satelite box to the HTS, connect it to the TV. No additional cables are needed as the HDMI already connected to the HTS uses ARC and will send the audio signal of your cable/satellite box to the HTS/receiver. Also, for those who use apps from your smart TV, the HDMI ARC will also send that audio to the HTS/receiver.

Works as expected for me - without disabling Anynet or having an extra cable. I'm happy. =)

Hope this helps.
