Hello,
I have a radeon graphic card with one hdmi and one display port connector. I can successfully connect two televisions (one to the hdmi and other to the display port) and get the (same) image on these. However i could only get the sound on only one television at the same time. I'm wondering if there is a configuration in pulseaudio that would force to send audio to both monitors.
