Telling by the messages from dmesg the audio device is already present when the module loads so it doesn't toggle it.
Are you using any other workaround to make it visible before or is it there on boot?
I'm not using any other workarounds. I then upgraded to On a fresh boot, before connecting HDMI cable, nvhda is already on. Ah, ok. So it was working with What exact kernel version are you running? Please post the output of dmesg grep -i nv so I can see in which order the driver loads. Kernel is as posted in first post: 4. I still have to do the additional step of:. Ubuntu Still having the same issue with updated kernel 4. Problem is, it's a general kernel problem.
This is currently kind of fluctuating and subject to investigation in the nouveau thread mentioned, it's not fully understoood yet. Hello tamer-hassan. Issue has returned, in Fedora 32 rawhide : kernel Go to volume control configuration, profile, select HDMI device unplugged unavailalbe.
Start sound app playing. Do this for each video or sound to force it out through HDMI. Of course, this workaround is less than ideal as HDMI audio should be detected and automatic. But it confirms HDMI is actually able to play a sound. All other system messages are similar to previous comments.

I'll have to look into what changed in the Ubuntu kernel.Fortunately, the fix is simple and there is no need to install additional drivers or make huge changes to configuration.
You should be seeing the desktop background on your TV. This is not typically seen in most of computers and hence need for this article. If you are successful, you are the luckiest and thanks for being here! But, the trick is the permissions is now freshly added with the HDMI audio profile. HDMI audio Output. Surround Sound. Also, do you know of any Linux Distro that will work like Android? Some distro that could be used with remote control — for TV… Cheers!
I did hear about it and hope to try it out soon. It is one of the best media players out there that is highly optimized for home entertainment. Me too. Running Mint Thank you thank you. This simple fix did seem to finally fix the issues I was having with no audio through HDMI connection. Hi Bob! Did you follow the instructions exactly? I did not do it the first time! After restart is completed, connect HDMI cable. Tried this, but the display refused to recognize the signal.
In any case, I had to reboot again with everything connected to get the display to work again. Sound test: fails. All the tricks listed here: fails. Tricks from other sites: failed.
Did not work on Juno. Added my user to the audio group and restarted but still nothing. So sad this is a bummer. Going back to Ubuntu I tried another workaround by installing PulseAudio. This did work for me to play sound through the hdmi, but then going back to internal speakers did not work when I disconnected it! Now I am without sound from any mint programs. Any more ideas? But, other than that, there is no change.I tried an old monitor HP LAwg 19" no signal too.How to enable HDMI Audio with Linux
Upgraded Xenial to Bionic, installed the latest kernel 5. Today install the latest open graphics drivers for Bionic without success, probably another person can be useful. Tested with many distros, all with the same error, currently use Disco Dingo to try to solve the error, probably HDMI hardware port error.
Your logic is sound. I would suggest checking the Monitor before the Computer, by using your same process of elimination if you can get another monitor available. This is odd From what you posted above, it would appear to be a hardware issue. However, this post suggests otherwise. Ordinarily, I would suggest trying a different Kernel.
But you also pointed out that you tried it with several different distros- so, either each distro was using the same kernel that conflicted with your specific hardware- or your hardware has a voltage fault.
Just the same, what happens if you try booting up from the older 4. I have tried many kernel versions, 4. I can only think of a hardware failure or since the kernel uses the free version intel drivers already integrated in the kernel.
Yes, I was typing that as I was thinking of Possibilities, before I read your post right above mine. Either way, given your extensive testing- I have to agree Though I am not an expert that it sounds like hardware even though it is usually not. Sometimes it is. I chimed in since no one else had It can help to have someone feel your pain even if they cannot carry it away.
I did try searching up anything that may cause that issue that is not hardware and it is what we both already mentioned above- Kernel issue and even then it is not the best possibility since most of those issues stem from a much older kernel than what is currently in use. It is not worth the cost of vga and buying a new laptop either, the laptop works fine with everything. Many machines out there are built with Windows in mind. It IS the dominant O.
On occasion, this means that the finickiness of the machine can more apparent in some than in others and troubleshooting it can be very difficult. When you ask about things that could be hardware Issues on a forum, it is less easy to get any response because most people will think along the lines of "We cannot do anything about Hardware at a distance over the internet.
Assuming for a moment that you do not have Broken Hardware; you may be running into the problem above. It may be that there is an obscure solution out there that few people know or would know as they do not daily write for this particular programming.
How can I force the HDMI to be enabled and connected during boot, irregardless of whether or not it detects a monitor? The GPU would not boot if the monitor was disconnected. If the monitor is connected, then everything boots fine. We ended up changing a setting that allowed for an empty configuration and it worked fine.

It doesn't seem like a solution - in my case I do not have X. G-Man Says 'Reinstate Monica' I had the same problem with my Debian 9 install; service lightdm restart did the trick for me.

My main desktop died recently, so my laptop running Slackware 64 I'm trying to setup a pseudo-docking station at my desk, and everything is working except hooking it up to my 27" LED monitor.
This is my first experience with multi-monitor support in Linux, so I started by running xrandr and get the following output: Code:. Last edited by flokofcgulls; at AM. Reason: additional info. OK, I figured out what was going on. I finally stumbled across this wiki article explaining the issue. To fix it, I had to completely remove all the bumblebee packages they were all marked with bbsb to make it easyremove the nouveau-blacklist package, then reinstall mesa and mesa-compat Since I think the blame for this problem falls on nVidia for not releasing proper documentation for their hardware, I'm reverting to the nouveau driver.

I used balena etcher to flash my sd card, which I have used in my previous raspberries and works properly, but it does not send any signal to the micro HDMI cable I use.

Raspberry pi 4 no hdmi signal Ask Question. Asked 8 months ago. Active 8 months ago. Viewed 3k times. Could this be a faulty raspberry pi or am I doing something wrong? George Sp George Sp 1 1 silver badge 4 4 bronze badges. This may or may not be relevant, which is why I'm writing a comment rather than an answer.
I reformatted it using a program called fat32format, and it's booting up fine now. JaromandaX I have tried to ssh to it. But it is not discoverable and probably has not even got an IP to ssh to. I have scanned the lan with nmap and did not find the pi. BZ1 I did not know that. I will try it and report the results.
Just to be clear, you mean to format to FAT32 the sd card and then flash it again, right? Formatting will obviously remove any data, so you will need to put it back on.
Fix no audio through HDMI when connected to TV in elementary OS
I'm not familiar with balena etcher, so I don't know whether it alters the type of filesystem. I was using NOOBS and just copied the data directly onto the card, so whatever filesystem it was formatted as remained the same. Here is the program I used to format it as fat ridgecrop.

I'm running Ubuntu I have Windows 10 installed on the same laptop and it works in Windows Currently xrandr -q outputs:. Anyone recommend anything or trying anything? When I plug in the HDMI chord the monitor's power light turns blue, then a few seconds later it says "No signal detected.
I was facing almost the same problem. I suggest you to remove your nvidia drivers in case of having nvidia drivers and reinstall the latest version and once booting again enter you secure password that you set while installing the new nvidia drivers while booting Mok and that's solved my issue.
