Hello、
I use OBS and Decklink Mini Recorder for 24-hour live streaming.
However, there is no sound about a week after the streaming starts.
The meter of the audio mixer will not swing.
"BLACKMAGIC Device" is selected for Device.
The input for decklink is SDI.
pc is core i7-10700 memory 16GB/win10 64bit 20H2.
I tried adding a frame synchronizer to the previous stage so that the sdi signal would be stable, but it didn't improve.
When this happens, change the Blackmagic device input from SDI to HDMI and switch back to SDI to get rid of it.
I would be very grateful if you could help me. Thank you for your cooperation.
