Can someone help. I have the thunderbolt and and when i go on u tube it plays but with no sound. The media sound is all the way up does anyone knwo how to fix this? I really dont want to go to verizon
try clearing the cache. settings-->applications-->manage apps-->select the "all" tab"-->youtube. then clear the cache and clear the data. not sure that this will work, but it's worth a try.
Thanks previous poster for your comment! Clearing the cache does resolve a lot of minor application issues on Android devices.
Thunderbolt7, are you using the YouTube application or going to the browser? Does sound work for other videos? Please let us know if the previous suggestion worked for you or if you are still having any issues.
