I work with a local TV station, and we're having a really weird audio problem and I'm wondering if anyone here has ever experienced anything similar.
We just built a new control room around an ATEM Television Studio switcher with audio fed via the AES port from a Behringer SRC2496 A/D converter. Everything seems to check out on all the audio outputs from the switcher (SDI, HDMI or the USB port for recording directly to a computer). The audio sounds fine on both the left and right channels; levels are good and not overmodulated.
When broadcasting the ATEM's output (whether live or off a recording), the audio sounds fine on most TVs, and again, matches levels with other content (i.e. video off our video server).
HOWEVER, if a viewer's digital converter box or cable box is connected to their TV via the RF modulator and a coax cable (as opposed to, for instance, composite video and audio cables), NO audio can be heard on programming originating from the ATEM (again, it doesn't matter whether it's live or if it's pre-recorded and played off our video server).
Has anyone ever run into an issue like this? Any suggestions or advice would be GREATLY appreciated! Thanks in advance....
