DP HDMI audio unplugged unavailable in Pulseaudio

Hi, since the latest kernels, or maybe latest nvidia update, my DP HDMI audio shows always unplugged/unavailable.

Alsa sees the card, but maybe there is a problem with the sinks, I don't know. I saw similar posts and tried every solution without success. I use LXDE.

Actually, the only command that works for me is this:
sudo systemctl restart lxdm

Then, the HDMI audio becomes available.

Is there anybody who could help me identify where the issue originates from? I have the feeling there is something broken in some update.

Re: DP HDMI audio unplugged unavailable in Pulseaudio

Hi, for me HDMI audio passthrough works. However I remember last year having a similar issue - it was because of Nvidia drivers and it took ages to get it fixed. The thread is there: https://bbs.archlinux.org/viewtopic.php?id=242227
Curiously this looked like a race condition linked to the boot screen display, see my post here: https://bbs.archlinux.org/viewtopic.php … 5#p1837945 Note I still have sometimes the display issue, but audio always work. Interestingly you can at least make the sound work through the systemctl command, suggesting this is a lxdm issue.

That said, you should provide further info: hardware and driver versions.

Re: DP HDMI audio unplugged unavailable in Pulseaudio

I noticed that it happens randomly at boot, but with an incidence of maybe 90%.

Yesterday there were updates of pulseaudio and today it was working. Still early to say. I also noticed in one case that, with enabled USB headphones instead of the DP HDMI for audio output, the DP HDMI was available after boot. So, it's like the issue happens when the DP HDMI is selected and you reboot with that setting. Then, it is not recognized.

Re: DP HDMI audio unplugged unavailable in Pulseaudio

I do not know if that is the same bug, or related. However, the random incidence at boot sounds similar. That said, I have had no issue at all since the fix in driver v. 430.26. At the time, I was unable to find a command that would allow the sound to work, as you do, but maybe I did not find it.

For your info, the thread on Nvidia's developer forum was there: https://forums.developer.nvidia.com/t/a … vers/67795 and Nvidia's fix acknowledgement in driver 430.26 is there: https://forums.developer.nvidia.com/t/l … ease/76170.

Re: DP HDMI audio unplugged unavailable in Pulseaudio

Try this :

killall pulseaudio
rm -r ~/.config/pulse/*
rm -r ~/.pulse*

And then reboot

This didn't work. The issue persists.

I observed that, at a fresh boot, the LXDM login is shown very small. After I have logged in and restarted LXDM, the login prompt is big, like it loaded the nvidia kernel module correctly (usually, nouveau displays so small characters and icons, while nvidia displays everything quite big). And after login, HDMI audio works indeed.

I don't have nouveau. So I don't know what exactly goes in the way.

Re: DP HDMI audio unplugged unavailable in Pulseaudio

This sounds like a race condition issue, set up your initramfs to preload nvidia modules: https://wiki.archlinux.org/index.php/NV … de_setting (... you don't need to add the modeset parameter, but that can help with a few other issues like proper VT switching) the important part here is configuring mkinitcpio properly (... and you might want to forego the nvidia_uvm modul from that list if you are currently on a 5.9 kernel variant as that is currently not loading due to kernel changes).

I used the mkinitcpio hook, rebuilt the Linux image, rebooted, and it worked. But only one time. All other reboots have the same issue. Still not solved.
