My media would not play and I thought it might be related to the Marantz template. So I wanted to disable the Marantz device. However when I tried to press save LinuxMCE complained about the Volume Level which was set to -43 in the template (which was also the actual level on the amp). I had to put it on 0 to be able to save it. After that the media would play again. When I re-enabled the device playing media failed again.
Is this a bug and is there a workaround?
look at the thread in the dev forums
