I finally decided to run Audyssey due to my receiver no longer produces any sound. So i get to the point where it tells me to adjust the volume level on the sub-woofer to 75 db. This is a powered sub, however, the volume level has only hash marks, there is no indication of any db hashes. The manual indicates to turn it to maximum and press ENTER to proceed to next step. On doing so, nothing happens, I cannot go on to the next step. So I am totally stuck.
The sub is a Polk Audio PSW505, if it matters.
Any help appreciated. If I cannot get this working, I guess I will have to install my Denon 2312, or go back to my Onkyo TX-NR906, which I had problems with it in the past.
