Sound problem fixed on iPad ...
It took me a while but I figured it out.
I had setup the lock button on the right upper corner of my iPad to screen lock (as opposed to mute/unmute ).
When I changed it back to mute/unmute - the default option in the settings app , it started to work.
I'd say this is bad sw coding ... But atleast we have a workaround
Good watching now
I have never messed with the lock button on the upper corner. My iPad1 has not been messed with as far as settings go. So are you saying that as the iPad is set from factory defaults only the content is muted but not the advertisments? And if you mess with the settings so that the lock orientation button becomes a mute button then it will work? I do not understand this as all.
Since iOS version 4.3 (I think) you have thhe option of configuring what the lock button does. the default being mute/unmute .i have changed mine to lock rotation ( the other alternative ) because it makes easier to read books.
after i returned that setting back to mute/unmute , crackle started to have sound on the movies/episodes. that was the only thing i had changed.
So, if you haven`t changed that , maybe i am just mistaken and theproblem was something else.
in any case, this problem only existed with crackle . everything else worked fine no matter what the lock button was configured to ( netfilx, pandora , youtube, playon, etc, etc ).
so it is really a "crackle' issue whatever it is . my guess , having worked inn the computer/software idndustry for the last 25 years , is this software was just not properly tested / debugged being hitting the road ...
I hope this helps you and other people.
