QLED Televisions: Update 1402.5 Causing Soundbar/Home Theater Connection issues

[capnfalkon]

Permanent fix for eARC Soundbars:

Goto All Settings \ Sound \ Expert Settings

Switch eARC to Auto

I've been using it like that for days and days - no drops!

=================================================================

Temporary fix for non-eARC Soundbars:

Goto

All Settings

Sound

Expert Settings

DiGital Output Format

Select PCM

Works for me. Couple of hours without a single drop.

Id suggest we each take this with your local Samsung distributor. The more pressure we put on them the better.

==============

Original Story:

I have a per of QN90c 75" TV and a Q990B soundbar.
After the TV was updated I immediately noticed sound drops with my soundbar. The drops would come at random intervals. Resetting the TV does not help. Neither does changing sound modes. Output via TV Speakers seems to be working fine drops-free.
Searching online i found a few more similar cases with different Samsung TV models and Samsung soundbars affected by the same firmware.

Here's one:

This will give me great pause on ever buying Samsung again. It’s quite obvious with all the posts the issue was related to the update. And for Samsung not to just simply come in here and be able to acknowledge the issue is quite disturbing. There are Reddit threads about the issue. 
There is a news post about it in SAMmobile.com
