Below is an email I just sent to support, was curious if anyone else saw this and if they did whether it tied up with a software update.. I wonder if they changed Dolby Digital processing at all recently. I forgot to mention the TV im using is a sony KD 43x8305c (fairly old but has been an awesome tv) ;
My bose soundbar 500 has developed a fault with either its built in sub or right end speaker. I can't quite tell which. Whenever I play a source with dolby digital 5.1 it crackles when there are bassy/ low frequency parts in a program. I have tried multiple sources, netflix, skybox and its only the content with dolby digital 5.1 that causes the issue. Now on the sky box I can mediate this by disabling dolby digital on the settop box but netflix is built into my sony android tv and always passes through the source audio format so I can't change it.
Steps to try bypass the issue: [Factory Reset(no change)], [HDMI cable swaps(no change)], [Set all levels to 0 and turn off adaptive IQ(no change)] [Rerun adaptive IQ, after factory reset(no change)] [switch to optical, (no change)] I also borrowed a Sony HT-SF150 from work which does not exhibit the issue.(all be it it doesn't sound as good)
I can loan a Quantum Data 780 series hdmi analyzer which might help to see what signal the bose isn't coping with but might need assistance from one of your engineers to setup the capture. (even though i think its probably a hardware fault)
I have also uploaded some images and videos up a public google drive account for you to review: *Edited by Moderator* its clearly audible in the videos as a rattle/crackle. *SNIP*
