HDMI recognized as "unplugged", after installing drivers
Solution 1
Thank you! Running this command mostly solves the problem:
pacmd set-card-profile 0 output:hdmi-stereo
If not, pressing Ctrl+Alt+F1 and then Ctrl+Alt+F7 solves it.
Solution 2
I had the exact same thing with an old Radeon 6900 Series.
To see info on pulseaudio
devices:
pacmd list-cards
Look for the card's index
and, under that, profiles
. For instance, I had:
2 card(s) available.
****index: 0****
name: <alsa_card.pci-0000_01_00.1>
driver: <module-alsa-card.c>
owner module: 6
properties:
alsa.card = "1"
alsa.card_name = "HDA ATI HDMI"
...
profiles:
****output:hdmi-stereo****: Digital Stereo (HDMI) Output (priority 5400, available: unknown)
Those bits of info are then used to set the output profile:
pacmd set-card-profile 0 output:hdmi-stereo
Note that the set-card-profile
parameters are the card index (0
) and the output (hdmi-stereo
).
After that, things just worked.
Queues came from here mostly: PulseAudio reports HDMI Audio is unplugged from the Nvidia MCP79 device
Solution 3
I have the same issue. Each time I suspend the system and wake it up, pulseaduio
says HDMI is unplugged. I do the following:
-
Press Ctrl+Alt+F1 to go to a terminal log in.
-
Then press Ctrl+Alt+F7 to go back to the GUI.
After that, pulseaudio
says HDMI is plugged in (under Output Device).
Solution 4
You cant do this on the default sound properties you need pauvcontrol
sudo apt-get install pavucontrol
pavucontrol
go to the configuration Tab
find your device
choose a profile that is plugged.
updated: fixed typo in pavucontrol
Solution 5
I have struggled with many solution but the only solution that worked for me was set audio on
with xrandr
as below:
xrandr --output HDMI-1 --auto --set "audio" on
and then HDMI device changes to plugged in
in pavucontrol
panel.
OS: Debian bullseye

So I'll start by explaining my situation.
I actually have had my current installation for some time now (Though I upgraded from 14.04 to 16.04), and the computer I used is an inexpensive one I bought just a few years ago, and slapped Lubuntu on. However, it comes with an integrated AMD GPU, that I never installed the driver for. The consequence of this was being completely shut-off from OpenGL, which wasn't something that bothered me enough to go to the trouble of installing a driver for. Until certain software I use started making use of OpenGL.
Well, a few hours ago I decided to install the proprietary fglrx driver provided on AMD's website.
First thing I noticed was that OpenGL content now works.
Second thing I noticed was that sound doesn't. PulseAudio outright lists it as "HDMI/DisplayPort (unplugged)", even though the video still shows on my screen.
So I've been trying to make use of Google to find a solution to my issue, but nothing seems to work for me. So before I go mad, I've decided to ask the community.
Some more information:
I make use of PulseAudio to manage my sound, mostly because Alsa never seemed to even recognize my HDMI audio, and because my keybindings for adjusting Audio never worked for some reason. I have tried reinstalling PulseAudio, with no success.
Something I have already tried during my search (as some people seemed to suggest), was editing /etc/default/grub, and changing the line
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
toGRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.audio=1"
. Even after rebooting, there is no change.I've also tried adding my user to various groups, such as "audio", "video" and so on, as that suggestion also came up in a few searches. No change.
On person claims they simply changed the profile for their devices to "plugged", but I don't see any way for me to do that, assuming I even can.
If anyone has a solution, I'm all ears.
Edit: I ended up reverting to the "Open Source" drivers provided by Ubuntu, but for some reason, I am still having the same issue. PulseAudio still says "HDMI/DisplayPort (unplugged)" is shown, even though the HDMI video is clearly working.

Thanos Apostolou almost 8 yearsTry login with the guest user or create a new temporary user and see if the problem still exists. If not, then it's a user configuration problem so try deleting the file
~/.pulse-cookie
and the folder~/.config/pulse
and reboot. -
am70 over 2 yearsToday I installed an update that says: Pulseaudio: Version 1:15.0+dfsg1-1ubuntu2.2: patch d/p/0001-card-restore-setting-preferred-ports-in-entry_from_c.patch, - cherry pick an upstream commit to fix the issue of hdmi can't be restored after s3 resume (LP: #1951667). Maybe it is related to your problem

hlongmore over 5 yearsI often have this problem because I frequently take my laptop on the road. I have to admit I didn't try the command line, but the key sequences are faster than typing the command (I guess I could set up an alias that makes it untrue), and worked like a charm. Are there any downsides to using the terminal login trick?

BjornW over 3 yearsI just started having this problem on my HTPC since some Ubuntu upgrade about 4 weeks ago (I run 18.04LTS on it). The HDMI shows up as (Unplugged) randomly at boot, sometimes it's plugged, sometimes its unplugged. If its unplugged, I have to do "pulseaudio -k" to kill the daemon and usually it then works after it restarts. Really weird, it has worked for several years without any hiccups. And since it works sometimes, it can't be a configuration issue either, it must be an upgrade of some of the daemons or programs that now is unstable :/

am70 over 2 yearsfor me it does. In the last month when I boot and first login, or when I recover from suspend, I see ""HDMI/DisplayPort (unplugged)" or sometimes the HDMI output is not even listed;
killall pulseaudio
solves the problem each and every time:pulseaudio
then restarts itself, rescan devices, finds all the existing devices, and it works as expected, with no need of any other action.
