During evaluation for ADV7625, I have found an issue for snow noise display. TXB is dedicated for DVI (with HDCP) sink.
The situation can be repeated with following setup. DVD1 -> RXA, DVD2-> RXB, TXB -> TV. Use command “route a/b txb”to switch between input channels. Out of 20%, there will be snow(1~2s) before stable picture. My software version is 2.2.1Exp4. Could you please give a clue about how to disable Freerun mode after unplugging RX? I have tried to change codes inside app_notify.c for many means but failed. For example, setting FreerunDisabled=TRUE; return early in ProcessFreeRun() function.
Please take a look and give explanation.
