For the first 2 years that i owned this unit it was super awesome, but as of the latest firmware update it keeps turning the sub volume down to -15 (all the way down), will even do it in the middle of watching something. This problem is so annoying and i did not go the extra mile by getting 2 subs, thx rated ones, to have them sit there doing nothing cause my Onkyo keeps turning the volume down to them... does anyone know (1) why this is happening (2) how can i get it to stop ???
