I thought this issue was put to bed, however, after reading CurtB comments, I gave it another try. Now, CBS/2 has SAP ON with sound, but when you turn off, sound disappears. COX video people may be doing a channel search first, then setting the SAP to On as your default. The questions begs as to why was it off in the first place. My ABC/7 seems to be now working with the default, and did not 2 days ago.
I'm still waiting for a simple explanation as to what the 'fix might have been. I'm sort of giving up checking this thing out, mainly be cause I do not use the web interface or App, except to chime into forum questions.
