I have a VMS1100 Arris set top box connected to my TV via HDMI. My TV outputs audio to a Panasonic audio system via optical audio cable. Similarly, I’ve a DVD player and XBoxOne connected to the same TV via HDMI also and audio for both works fine. But i couldn’t figure out how to output the STB audio to my audio system. I’ve tried switching HDMI cables, optical cable from STB to sound system, User Settings on the STB (LPCM, Auto, Pass Through) , cold reboot everything but still no audio coming from STB. Any other ideas?
Thanks.
