I bought a cheap TV, the EKO 75" for $850 (https://www.bigw.com.au/product/eko-75-4k-ultra-hd-smart-web…). The sound was terrible and tinny, so I bought a soundbar - a Panasonic (https://www.thegoodguys.com.au/panasonic-31ch-soundbar-300w-…)
After watching FTA TV, Prime Video, Plex anything for that matter, for more than 6 minutes, the AV delay becomes very noticeable. I've tried using PCM and Pass Through with no luck. Tried manually setting the audio to MPEG, Dolby, Dolby DTS Plus but all seem to have a delay after 6+ minutes. There's a AV sync correction but the delay gradually increases so setting a Xms correction doesn't fix the issue as it doesn't exist at the start.
I thought a HDMI 2.1 cable might fix… faster cable… faster data transfer but no. Same issue.
Is this an issue with the TV or the Soundbar?
can you take soundbar to a friends place?
even better to bring someone else's properly functioning soundbar to your place
