Unfortunately problems like this have been happening with cable/sat boxes since HDMI first appeared. HDMI "handshake" issues are exacerbated when the device goes through an HDMI switch, so connecting direct-to-TV is a logical solution.
Honestly, the "one cable to the TV" thing is pretty overrated. Running a second HDMI cables to the display obviates the need for any "standby passthrough" because the AVR is out of the chain, plus you get more flexibility (e.g. you can watch TV from the cable box while playing a different audio source on the AVR).
