Hi everyone - I have a project that had a SWAMP connected to a Sonance DSP on SDPIF output 9. The DSP amp never powers off it's always in standby, so whenever the output gets set to zero in programming audio ceases. I received a client complaint that this zone was turning on when zone 1 was being turned on to input 1. This makes zero sense because the pool zone on SDPIF output 9 can't turn onto this source in programming - the analog initialize symbol doesn't allow 1 as a value. The Sonnex tool would show None as a source even though the audio was clearly present.? After troubleshooting with True Blue they determined a hardware issue and authorized advanced replacement. Replacement installed - the same problem. I discovered that even though SDPIF output 10 isn't even defined in my programming, it was turning on to input 1 as well, so both SDPIF outputs are doing the same malfunction on 2 different SWAMP units. When I select an audio source for the pool on output 9 (that is defined in programming and is supposed to work) it turns on and when I turn it off it turns off. This is where I noticed a behavior- once I do this the malfunction stops. It only returns when there is a power cycle of the SWAMP. It appears that a power cycle of the SWAMP does something to cause outputs 9 and 10 to recall input 1 on zone 1 until you choose another source and shut it off. I've got a workaround completed but I've never been this before and I can create the condition consistently now that I screwed around with it today in person. Anybody else have this condition on the digital outputs? I've done a few with AVRs on these digital outputs which always turn on and off with the zone so I've never had this happen before. The fact that this DSP was remaining in a powered-up state seems to have allowed the condition to present itself.
