    No HDMI Audio Options in KDE Fedora 30

    I've been away for a while. I've been using Neon, it's a KDE distro based on Ubuntu. My setup worked fine using it. I just switched back to Fedora today and now I can't change my audio output to my HDMI monitor (with stereo connected to it). When I go into Settings - Multimedia - Advanced - Built-In Audio Profile, all I have are Analog Stereo Input, Analog Stereo Output and Analog Stereo Duplex. None of the HDMI options are listed there.

    I installed the Nvidia driver from Nvidia, couldn't get things working with RPMFusion. I have the RPMFusion repo setup though. Could I be missing some sort of driver or codec?

    Re: No HDMI Audio Options in KDE Fedora 30

    Maybe HDMI is off in the bios?

    Re: No HDMI Audio Options in KDE Fedora 30

    No, this is another Fedora thing. I'm dual booting, KDE Neon and Fedora. I want to switch to Fedora but I just can't because things don't work as they should. This is one of them, as is the other thread about the brightness. When I'm booted up to Neon, I have the HDMI output as an option but in Fedora I don't. So same exact hardware, different OS.

    Re: No HDMI Audio Options in KDE Fedora 30

    I would uninstall the nvidia driver as I've had nothing but trouble using the default repository. Try reinstalling with this guide 'https://www.if-not-true-then-false.com/2015/fedora-nvidia-guide/' (try this one by itself first but use 'https://linuxconfig.org/how-to-install-the-nvidia-drivers-on-fedora-29-linux' if you run into a stumbling block with the terminal, especially around editing with nano and the nouveau drivers)
    After that, go into the sound settings and change the default audio output to HDMI, turning off other audio ports as well in the settings if required.

    Re: No HDMI Audio Options in KDE Fedora 30

    In my experience, especially with Nvidia drivers, on Fedora they only have reliably worked when you use the terminal to install them, as the app stores don't seem to properly configure drivers and repositories (I would only get 3rd-party apps listed after re-entering the repos in the terminal after trying to enable it in the app.)

    Re: No HDMI Audio Options in KDE Fedora 30

    The HDMI audio from your Nvidia card was not listed in your inxi report. Since that audio comes from the nvidia card, it's not likely to work without the proper driver.
    I've used the rpmfusion repos (both free and non-free) since 2005 and have had very little trouble with the driver working properly.
    Install both rpmfusion repo's, remove any nvidia drivers you have put in then it's as easy as open a terminal, sudo dnf install nvidia-driver akmod-nvidia ,,then reboot.
    Nvidia shows that your card uses the current driver and should be fairly simple to install.
    I have a couple of machines that use nvidia cards with HDMI outputs and without the Nvidia driver there's no audio.
    Give it a try, Good luck.
    (It's a hobby, but I like it)

    Re: No HDMI Audio Options in KDE Fedora 30

    It does make sense that it would be the video driver, since it's literally going thru the video port. However, I've tried installing F30 on my laptop a half dozen times. Each time, I get everything updated and install the Nvidia drivers from RPMFusion and when I reboot I get a black screen. This time I downloaded the driver directly from Nvidia.com and afterwards I was still able to get into the GUI. I'll try Bionical's suggestion of https://www.if-not-true-then-false.c...-nvidia-guide/' and reply back later today.

    Re: No HDMI Audio Options in KDE Fedora 30

    well, I haven't logged into Fedora in a few days. I rebooted into it and saw there were some updates available so I installed them. Afterwards I went into the Power settings to check on one of them and saw that the brightness control was there. So I then went to the audio settings and the HDMI output is there. Strange this update addressed the issues I was having. Still having other issues, but they're much smaller, at least to me. Thanks guys for your input.

    Just for the record, I installed all updates and rebooted several times before making the original post.
