Hi All,

Have recently purchased a MatroxMXO2LE + Matrox MXO2 ExpressCard Host Adaptor ExpressCard/34.

I intend to use it as a camera/microphone input in Adobe Connect on-line webinar software.

I have a audio switcher inputting to the Matrox box via XLR cables.

I have a standard microphone connect to the audio switcher.

Camera input Via HDMI from a Atem TV Studio Switcher into the Matrox box.

Matrox box connected to MXO2 ExpressCard Host Adaptor ExpressCard/34 via the host cable.

Running Windows 7 Professional 64Bit.

I have configured the Webcam Emulator so I can use my camera/microphone as a webcam/microphone throughout Adobe Connect meetings.

The issue I face is that the audio is not outputted through to the PC unless I have the Matrox Utils open or I have the camera sharing inside Adobe Connect, pausing my camera through Adobe Connect also stops audio from being received to the PC.

Cheers,

Daniel

Hi Daniel,

Yes, you will need to have Matrox application opened in order to initiate a passthrough of the MXO2 Hardware.

Is there a workaround for this? Or is that just how Matrox works?

That can't be entirely correct.

The Adobe Connect meeting room (your site says it supports Adobe Connect) can output audio from my microphone with Matrox application closed, but for some reason the camera feed needs to be on for microphone to work.

Hi,

Is the audio coming out of the MXO2 into sound card as mentioned in our User Guide on page 212?:
http://www.matrox.com/video/media/pdf/support/windows/mxo2/doc/en_Matrox_MXO2_Installation_and_User_Guide_7_7_1.pdf

Note If you want to use a microphone input for your audio stream, you can
connect your microphone directly to the microphone input on your system's
sound card. If you want to stream an audio input connected to your MXO2
hardware (such as to stream the HDMI or SDI embedded audio), use an
appropriate adapter cable to connect any of the audio outputs from your MXO2 hardware to the microphone input on your sound card.

Hi,

Please find attached a diagram showing how we are using the matrox device in our environment.



Have followed the manual for the settings, audio and video do work, but we just want to know why Audio will only be outputted when a video feed(webcam emulator) is being shared through AdobeConnect.

The pass-through is only initiated or starts when the Matrox supported application, such as Adobe Connect, accesses the hardware. If the software is not started, the MXO2 box will not pass-through video and/or audio. This is by design. We do not support passing audio if the application is not accessed or opened.
