I setup a new wetek play 2 with the embedded OpenPHT and it is exactly what I was looking for and has the flexibility i needed to deal with an older soundbar with limited audio codec support.
While setting this up yesterday I ran across a thread in passing that explained how to shut off the led's on the wetek by ssh'ing in and editing some files in there. I didn't bookmark it and now I can't find it.
Does someone know what I am talking about and point me in the right direction?
I found an older article on openELEC that does the same thing, but it doesnt work for openPHT unfortunately. I think the specific filenames might be different.
