I’ve got a MX300 that has a Cisco DMP 4310g connected to it as a presentation source. The basic idea of it is that the client wants to use the MX300 for VTC and then when not in a call, be able to send the iptv feed from the dmp to the monitor as a presentation. Not really an ideal way to have iptv in your office, I admit, but the client wants it this way.
Anyway, the DMP is continually sending audio to the MX300, even when the presentation is not being sent to the unit. Pressing stop presentation on the remote will stop video, but audio still passes through.
The DMP video is connected to the MX300 via HDMI>DVI adapter. Audio is sent from the DMP to MX300 via 3.5mm stereo to RCA Male.
My question: is this normal function for the MX300? Seems like when presentation is stopped, both audio and video should stop, right? Is there something I’m missing in the configuration? Any help would be appreciated!
