I have a very specific problem with audio output on HDMI. I want to use an older notebook with Lubuntu 20.04 as a video source for libreoffice slides, videos etc. to feed them over HDMI into a Blackmagic Design ATEM Mini Pro ISO (video mixer) as one input.

I have same device ATEM Mini Pro ISO and Dell Vostro 3450. I can confirm, that bug exists and is possible to grab sound from only first port. Actually all ports on ATEM HDMI grabber are NOT same. HDMI1 is using different hardware than all others and is accepting sound from my computer. If I'm using HDMI2,3,4 port - then yes, no sound. To help debug problem, here is ATEM Mini Pro ISO teardown report with chip ID's for all ports - https://wphost.spider-e.com/?p=940 And here EDID report with connected HDMI1 and HDMI2: //HDMI1 sudo get-edid -b 5 | edid-decode This is read-edid version 3.0.2.

[Touch-packages] [Bug 1910537] Re: HDMI audio not working on Blackmagic Design ATEM Mini Pro ISO (video mixer)
Pretty good hint, interesting. However, the ATEM is definitely able to take audio in on all four HDMI ports, since it has level indicators and buttons to turn it on and off (and AFV=Audio follows Video) and adjust the level on all four HDMI ports. And I do have a camera with a builtin Mic (GoPro 4) on HDMI 2, which perfectly takes the Audio from the camera mic. So there must be some difference in the HDMI signal coming from a camera (I had a Sony A6300, a Z-Cam e2c, and a GoPro 4 connected, all passing audio properly to the ATEM) and the HDMI signal coming from a Linux/Ubuntu notebook. The cheap chinese LCD screen I used for testing doesn't care about the difference, it just plays the sound, while the ATEM obviously bothers about that difference, but, as Uldis figured out, only on Ports 2,3,4. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1910537 Title: HDMI audio not working on Blackmagic Design ATEM Mini Pro ISO (video mixer) Status in pulseaudio package in Ubuntu: Incomplete Bug description: This is a complicated thing.

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 Touch seeded packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1910537 Title: HDMI audio not working on Blackmagic Design ATEM Mini Pro ISO (video mixer) Status in pulseaudio package in Ubuntu: Incomplete Bug description: This is a complicated thing.

There are a few sample rate-related settings in /etc/pulse/daemon.conf (or just make your own personal ~/.config/pulse/daemon.conf). You can edit that file and remove the ';' prefix to enable any settings. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1910537 Title: HDMI audio not working on Blackmagic Design ATEM Mini Pro ISO (video mixer) Status in pulseaudio package in Ubuntu: Incomplete Bug description: This is a complicated thing. I have a very specific problem with audio output on HDMI. I want to use an older notebook with Lubuntu 20.04 as a video source for libreoffice slides, videos etc. to feed them over HDMI into a Blackmagic Design ATEM Mini Pro ISO (video mixer) as one input.

The hardware data in comment #4 does explicitly say: Supported sample rates (kHz): 48 but I don't know if the Linux audio stack (PulseAudio + ALSA) is smart enough to honour that automatically. Sounds like it's not. Try making a new file ~/.config/pulse/daemon.conf with: default-sample-rate = 48000 -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1910537 Title: HDMI audio not working on Blackmagic Design ATEM Mini Pro ISO (video mixer) Status in pulseaudio package in Ubuntu: Incomplete Bug description: This is a complicated thing.
