My 970 had exhibited the 'freeze' both when the source is turned on before the 970 and when the 970 is turned on prior to the source. I usually try to turn on the 970 first, as it seems it occurs less that way. Fortunately, it doesn't happen so much to me anymore, and I just deal with it when it happens. It's a pain but the sound quality is still worth it. As I mentioned before I don't think there will ever be a fix at this point.
