No HDMI sound output on laptop

[Artos]

Hi, first post!

I freshly installed Mint 19 on my Alienware laptop. I had a lot of issues, first with an OEM partition that caused my laptop to go in recovery mode when Windows was deleted and then with GPU drivers where I had to boot in nomodeset and install the nvidia drivers for my gtx1060Mobile using the Drivers Manager. I tell you all this because I suspect the card and it's drivers could be linked to the issue, maybe.

Symptoms: I have no sound on my TV when I connect it in HDMI. By default the image shows up perfectly, as an extension of my desktop. I don't have the option to choose hdmi output in sound settings. I tried pavucontrol and same problem, I don't have any option to switch to hdmi there.

Here is the result of the inxi command:

Audio:

  Sound Server: ALSA v: k4.15.0-46-generic

Any idea on what could be the issue here?

Install pavucontrol and make sure the correct output device is selected.

I actually missed this on first read as well:

Hi Artos, and welcome to the forum.

Let's see the outputs of inxi -Fxz, aplay -l and pacmd list-cards please.

One last one, just in case: dmesg | grep -C1 -E 'ALSA|HDA|HDMI|snd[_-]|sound|hda.codec|hda.intel'

One of those should point us in the right direction to get this sorted.

I blame my advancing age. Apologies to the OP.

Hi, thank you for your answers, here are the commands you told me to do, I did them while plugged-in to the turned on TV of course. Seeing anything that could tell us what's wrong?

Hi Artos.

Your outputs show that HDMI doesn't exist as far as sound is concerned on your system. This is most likely solved by making a change in your BIOS. I was helping someone with something quite similar recently, and I think the fix was a "discreet" setting. I'll try to find the thread.

[MrEen]

I found the thread here: viewtopic.php?f=47&t=288514&hilit=discreet#p1598164

That user needed a fix I found here: https://devtalk.nvidia.com/default/topi ... 3/#5211273

I posted complete instructions (minus the sudo touch command a couple of posts later) here: viewtopic.php?f=47&t=288514&p=1602220&h ... t#p1602220

If you choose to try that fix, be certain to have a backup first. A Timeshift snapshot would be an excellent choice. You have the same busid for the nvidia card that the OP in that thread had (bus ID: 01:00.0) so the instructions should be the same for you assuming it's the nvidia card that your HDMI is plugged in to.

You can also check the output of running lspci in the terminal. You should have more than one Audio device (the one you will have will be at 00:1f.3) but I'm betting you won't. The HDMI audio should be either 00:02.1 if it's Intel, or 01:00.1 if it's nvidia. If lspci does produce a second audio device other than 00:1f.3, please report back before attempting the fix and paste the output it gave you.

If you'd rather try anything else first just say so and we can try some other troubleshooting. Start with a complete shutdown. Leave the system off for at least 10 minutes, then boot up and see if lspci shows either 00:02.1 or 01:00.1.

[victords]

Hi MrEen,

I have the same problem as the OP, but lspci does list two audio devices for me... Do you know what should I do?
I also created a post about my problem with the output of the other commands: viewtopic.php?f=48&t=350069.

Here's the output from lspci:
