Re: Roku with att tv volume goes loud and distorted and then back to normal
Started streaming AT&T TV on my Roku Ultra. The volume goes loud then soft. When loud the sound is about 5 to 10 on my Samsung tv and audio is a little distorted. When soft (normal) the volume setting is in the 50 to 70 range. Im pretty sure its only when streaming AT&T TV but I could be wrong. My coworker today decribe-ed the exact problem with his Roku. It only does once and while.
