Happy Sunday all.
2 U-verse boxes, Blu-ray player, roku 3
Above feeding into Monoprice 4x4 HDMI matrix swtich
Matrix outputs = VSX-1123-k, 3 TVs
VSX-1123-K feeds to Mitsubishi HC8300 projector
Here is my problem. The VSX-1123-k drops audio randomly when the uverse boxes are set to "surround sound", but the channel is broadcasting in stereo. Audio drop is something like a loss of audio for .1 seconds.
No problem when box is set to "stereo" and channel is in stereo.
No problem with box is set to "surround" and channel is DD
The display on the reciever does not flicker or anything when the audio drops, so I dont believe the uverse box is dropping the audio
Happens randomly, sometimes once a min, sometimes 5 times in 5 seconds.
What I have tried:
Software update on receiver
U-verse box direct to receiver (so the switch is not causing it)
Have a call into Pioneer call center but am not expecting much from them.
Am I doing something stupid?
