For the past couple weeks, every time I use my Roku I have to reboot it to get audio to work. I can here all the button navigation clicks no problem, but as soon as I start a program, there is no audio. Happens on all channels that I have tried. Once I reboot, audio works fine for the duration of the program.
Come back the next day to use it again, and I have to reboot again to get audio to work.
