We have IFP 7550-3 panels and have a need to get analog autio output for hearing impaired students. We can plug into the 1/8" output jack, but of course that shuts off the internal speakers. Does anyone know how to get both working simultaneously? We have tried intercepting the HDMI signal and splitting off 1/8" analog audio, but have intermittent issues with the HDMI signal dropping.
Thanks in advance,
