I hear what @pioneer is saying and agree. Sound is pretty fundamental to using the ATV as home theater setup, a mac, or even a server. So...
Given that 10.5.5 seems impossible to download at the moment (I'm willing to host but don't have it), what is the easiest way to upgrade my ATV1 to OS X (any version) such that analog audio works?
Does anyone have a version of OS X running on an ATV1 with analog audio working that they are willing to explain how they got it to work?
Thank you in advance.
