I am not sure which way to go. Read about others issues with HDMI on onkyo, I haven't had any in the past week. I have 2 speakers outside which I connected, plus have 7 speakers in my family room. Both units appear to switch properly and deactivate a set of speakers when using zone 2. I honestly haven't had any faults with either in the last 7 days of tinkering.
Also, if you happen to know the answer to this. Neither system found my subwoofer, tried various things with the sub and still nothing. When playing content it appears to work. I have two tall boy front speakers which the receivers tagged as full/large in the configuration. Read that I should leave these as small at 80hz to make sure that the bass is routed to the sub. This kind of confused me so not even sure if I need the sub anymore with these tower speakers. Any thoughts what the right config should be.
