I have my computer hooked up through HDMI into the TV. The TV is hooked up to my Sonos system through digital audio optical output from my playbar (also have 2 play 1s).



Computer settings are set to send sound through HDMI.



The TV settings are set to play through the External Speaker (sonos); however my computer sends sound only through the TV's internal speakers. All my other devices (Chromecast, Roku) play audio through the Sonos system which are both through HDMI. For some reason, my computer will not do the same.



Any advice is appreciated.



TV: Samsung 8080 series
What version of sound is the PC sending through the HDMI to your TV? If it's anything other than Dolby Digital or PCM/Stereo (like perhaps DTS) it won't work with the PLAYBAR.



It sounds like the Sonos is working properly, since it works with the Chromecast, etc, so I'm betting the issue is with the signal the PC is sending.
