Hello all,

I am having a problem with fluctuating volume levels on my analog outputs. I recently purchased a spare rack mounted 861v4 for parts / backup of my existing 861v4. When the spare 861v4 arrived it was in better aesthetic condition than my current system so I began to swap some cards and simplify the main processor. I ended up with the following configuration:

Spare Chasis new card configuration:

IA00
OA12x2
IE42
ID40
C00


Original Chasis 861v4 Cards:

IA00
VS00
RF00
OA12 x 2
IE42
ID40
C00

Spare Chasis 861v4 Cards:

S00
IA00
OE12
OA03
IE42
C00



After swapping cards I upgraded the processor firmware from 4.25 to 8.1. I then updated the configuration program with the updated card configuration and applied the configuration to the new processor.

Things seemed to be working well but I quickly noticed the volume level would almost double about 30 seconds after content playback began. The volume indicator on the processor does not change but the level of sound increases. If I mute / unmute the processor or power the system off and back on the volume returns to the normal level for 30 seconds or so and then jumps to the louder level.

I have typed the system as well as re-applied the firmware update twice without any improvement. I have not built a new configuration from scratch.

Any ideas on what might be going on? Any feedback would be appreciated.

Thank you !
