I've encountered an issue with my Samsung QN75QN85AAWXXY TV, specifically when it's set to "Digital Output Format: Auto" and connected to a Sonos Arc soundbar. Despite trying various cables and confirming the TV recognizes the e-ARC connection as it should, the audio intermittently cuts out. This problem arises whether I'm watching free-to-air TV or streaming through any apps on the TV.
Interestingly, when I switch the TV's setting to PCM, the audio dropout issue ceases, but this workaround significantly compromises sound quality since formats like Dolby aren't supported in PCM mode.
I'm reaching out to see if anyone has experienced a similar issue or might have insights or solutions to suggest.
