I want to connect a sonos playbase to the Samsung tv that does not have a digital audio output. This TV has a one connect box that has a HDMI-ARC connection, but there is no HDMI on the speaker. Right now the speaker is connected through the Directv optical output, which works but when I set the timer of the tv to go off at night, the speaker is still on and it wakes me up. Trying to the speaker connected directly to the tv. Thank you in advance.
