I think I've found the problem. @Uldis: please check and verify
It doesn't work with a video with Channel(s) : 1 channel Channel layout : C Sampling rate : 44.1 kHz but it works when playing a video with Channel(s) : 2 channels Sampling rate : 48.0 kHz So maybe it's the sampling rate. Probably Linux outputs a sampling rate conforming with the current source, and the ATEM seems to expect 48kHz, while accepting everything on HDMI1, but getting it scrambled and distorted, since there's not enough data (8% missing), while the input on HDMI2-4 simply doesn't match the expectations. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1910537 Title: HDMI audio not working on Blackmagic Design ATEM Mini Pro ISO (video mixer) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1910537/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
