Thread: OpenSuse Tumbleweed - ALSA not seeing audio

  1. #1

    Default OpenSuse Tumbleweed - ALSA not seeing audio

    Hey everyone,


    So I'm having a little trouble with ALSA seeing my audio output from my NVIDIA card.
    I moved to OpenSuse Tumbleweed from Debian 10 Buster, on buster the Display Port would send audio out to my monitor, and I would have a sound card that I could change between the internal PC audio, and the display port audio.
    I'm running ALSA version k5.6.11-1-default, and kernel 5.6.11-1-default






    As you can see, the output of aplay -L only sees my Intel card.

    I'm assuming that the ALSA kernel modules are not correctly loaded, which is why tumbleweed is not seeing my NVIDIA audio card, but I am fairly new to openSuse, and only just beginning my journey into Linux.


    If this is the case, then how do I update the ALSA?

    Hi
    I manually set the default sink here (I do use the intel display port, nvidia is used elsewhere);

    Code:
    {run as user}
    pacmd list-sinks | grep alsa_output
    
    name: <alsa_output.pci-0000_00_1b.0.hdmi-stereo>
    
    {edit default.pa as root user}
    cat /etc/pulse/default.pa | grep alsa_output
    
    set-default-sink alsa_output.pci-0000_00_1b.0.hdmi-stereo
    Plus you system is out of date.... (20200528, 5.6.14-1-default) is this because you use the repository nvidia drivers?

    It looks a little out of date as I wrote this issue down last week, but had trouble connecting to the forums here. I've actually updated the system, and kept it updated.
    I am currently using the proprietary drivers, but I have also tried the ones installed from the opensuse repo. I decided to install the NVIDIA drivers the hard way to see if it would resolve the issue. (obviously it did not).

    I will removed the NVIDIA drivers later, and go back to the repo ones.

    I think that this may be a bug with the kernel ALSA drivers, as my intel card seems to take up all of the channels. I remember reading about this somewhere. So I am thinking that I may have to either update the ALSA drivers, or roll back to kernel 5.5.

    Hi
    I use the 'hard way' here I would guess it's a bug, but you would need to switch back to the nouveau driver and duplicate before creating a bug report...

    So I have removed the NVIDIA drivers, and reinstalled them via the OpenSuse repository.

    I am reading through the document here https://download.nvidia.com/XFree86/...issues_in_alsa
    In section 10.3 it talks about under emulation of logical devices, and I'm wondering it this could be the issue.

    I don't see any NVIDIA here at all, only my onboard Intel.

    I'm thinking that to test if this is the issue, I either need to upgrade ALSA, or roll back the kernel.
    Neither of these I have done before, as I am fairly new to Linux. Do you think this could be the issue?

    I would like to be able to identify exactly where the problem is, before I raise a bug report.

    I wonder if you're impacted by this regression perhaps...
    https://lists.opensuse.org/opensuse-factory/2020-02/msg00307.html

    If you're dealing with HDMI audio with Nvidia binary driver, there was
    a known regression regarding HDMI hotplug notification on 5.5 kernel,
    and it got already fixed in the later 5.5.y kernel. You can try the
    kernel package from OBS Kernel:stable repo.

    The problem I'm seeing is that yast doesn't even see my NVIDIA audio output. There is no card registered at all.
    I know it works as I've had it running under Debian 10, POP_OS, Fedora and Ubuntu.

    I'm running the 5.6 kernel

    Uninstall nouveau drivers before installing Nvidia's drivers.
