I have not had a problem with this until today worked as early as last night even. I screen share my mac through my apple tv and today the sound doesnt come out of my soundbar that is connected to my tv like it usually does and only plays through my computer speakers. I reset everything and it plays through other sites and computer programs like it's supposed to. It's just the xfinity stream site that this no longer working properly.
Solved! Go to Solution.
I'm having the same issue today. I can airplay from imac to apple tv, video works fine but no sound. how do you clear the cache history?
Same problem here.
Occured about the same time as OP.
tv.xfinity site stopped transferring audio to AppleTV. All other audio from my Mac transfers fine. Even other sites. Exclusive to xfinity stream.
I cleared the cache the other day and fixed the problem, but only temporarily. About a day later it happened again.
Clearing the Cache whenever this happens is NOT a solution. As this negatively affects everything else in order to fix it.
I tried removing just the xfinity site data from the cache, but that didn't work. There must be some other listing burried in there associated with Xfinity that is not obvious.
PLEASE FIX THIS PROBLEM XFINITY
I am having the same issue. Video going to my TV, but sound only coming from laptop. I called Xfinity and they said it was an issue on my end, not theirs. Aparently they dont read these forums since others are having the same issue. I hope they fix it soon.....soon like today.
This is a known issue with the Adobe Flash version 27.0. Comcast contacted Adobe and this will be fixed in Adobe Flash's next release.
Below are some troubleshooting steps to try in the interim before an update is released.
