Second is probably not the standard "no audio" problem, since it's not random, but happens every time I listen to a CD, for which I use an optical connection assigned to the "CD" input. Whenever I start a new CD, I have no sound until the track has played for one second or so. It's annoying because I always miss that first second, so I now routinely start the CD with the volume down, hit the
button to start the track over once the 970 has picked up the digital signal, then turn the volume back up.
