Is anyone else getting this? I've heard it a few times but the 2 recent examples I bothered to remember were this one:

Where at around 14:37 the entire video actually, not just dialogue in this instance, went mute mid sentence and remained that way until 14:49

And then this one again today:

At around 29:48 where only the dialogue cuts out. The first few times I ran in to this I assumed the video had just had an editing error but it's happening too often for that to be it. I noticed recently that my laptop will do some kind of automatic downmixing of 5.1 audio so I can hear it in stereo, but only if playing through my laptops speakers and not through the dock it's connected to with attached speakers, in which case it only monitors some channels in a 6 channel audio source but I checked that by switching to the internal speakers for the sections of mute video in question and it made no difference.
