Just confirming the good news that Paul shared. Applied the update to my TV (Sony A80J) today, and it’s all working now. Thank you Sony!

Glad to hear! Which Firmware Version fixed the problem? I can only find v6.3628, which is dated to March 2021. Strangely, my A80J came with factory default v6.3640 in EU, which has the same issue.

My LG had a firmware update available, but no luck.  Latest update did not fix the issue.

GOOD NEWS to everyone, today Sony released a new firmware and it fixed all the LPCM problem that I had the last past months, sound is outputting at the correct channels when movies playing in LPCM.

Everyone please give it a try!


Got the same issue, Sony A80J. How do I download the firmware?

Have you figured this out? I’ve also got an EU Sony A80J preloaded with v 6.3640 and can’t find a newer firmware…

Unfortunately, no - still waiting for an update.

I am not familiar with Sony’s EU support website, but its US support website includes a chat function. You may want to check to see if that is available to get info on a firmware update for your your model.

Hmmm….Sony issued a new firmware update for my tv today…

6.3780 for A80J/A90J got released for EU which should fix the issue:
