I recently discovered that certain tracks will not play audio properly in the YouTube app and produce what sounds like a quiet squeaking/computerized glitch noise, but those same tracks play properly on my computer. Additionally, these same tracks played properly last week on my S4. I've tried clearing the cache and data in the YouTube app as well as disconnecting from WiFi (I've been reading about IPv6 issues) and using data with no luck. Has anyone else encountered this problem and found a solution?
