Hi all,
I’m running into a recurring HDMI/eARC issue that started after updating my Sony XR-55A80L to firmware version v6.8022. Hoping others can confirm or suggest a solution.
📺 My setup:
TV: Sony XR-55A80L (2023 OLED)
Amp: Sony TA-AN1000 (eARC capable)
Source devices: NVIDIA Shield Pro (fast boot), PS5
Connection: HDMI with eARC enabled
Bravia Sync: Enabled
Amp setting: Network Standby = ON, HDMI Standby Through = ON
TV Audio Output: Set to “Audio System”
eARC Mode: Auto
⚠️ The issue:
After the latest firmware update (v6.8022), I’ve been intermittently getting this message on boot:
“TV speakers active due to communication failure between the TV and audio system.”
The message appears at startup, particularly when using the Shield, which boots very quickly.
However, audio still routes to the amp correctly after a second or two.
The PS5 doesn’t trigger the issue, likely because it takes longer to boot and gives the amp time to complete the eARC handshake.
🔍 What I’ve tried:
Double-checked Bravia Sync and eARC settings on both TV and amp
Ensured HDMI cables are high quality and fully eARC-capable
Amp and TV both have latest firmware
Network Standby and HDMI Standby Through are ON on the TA-AN1000
No HDMI splitters or ARC extenders in use
TV now starts up faster after the update — may be outpacing the amp’s readiness
🧠 My theory:
It seems like the TV is trying to establish an eARC connection before the amp is fully ready, especially when the Shield boots quickly. This results in a temporary fallback to TV speakers before switching back to the amp. Since the PS5 takes longer to boot, it avoids the issue.
❓Questions for the community:
Is anyone else with an A80L or TA-AN1000 seeing the same issue after the v6.8022 update?
Could this be a firmware bug, or just a timing conflict due to faster TV startup?
Are there any recommended tweaks or CEC strategies that solved this for you?
Could this affect the TV or amp long-term, even if audio functions normally afterward?
Appreciate any advice or feedback!
Thanks in advance.
