I currently have a 4x4 HDMI matrix connected to two sharp and two sony TVs.
I also have two comcast boxes distributed over HDMI.
When I switch the Comcast box between the sony and sharp tv the sound drops on the Sharp TV-Specifically the Sharp displays the message that audio signal is not recognizable.
I then need to turn Comcast box off, change the HDMI audio setting from auto to L-PCM, the the sound returns. This change in the settings however is only temporary and when tvs are switched over the matrix, the same thing happens again.
How can I stop this? Is there a way to may these settings on the comcast box permanent? Am I missing something on the sharp tv that will make the tv recognize the audio? I would prefer not to purchase an EDID emulator like Gefen HDMI Detective plus.
Here is my equipment list:
Accell 4x4 HDMI Matrix
Sony 65w5100, 40w5100, Sharp 46se94u, 52BP80U
two motorola comcast boxes DCH 3200
