This article is mainly about "how to fix the problem that there is no sound when HDMI is enabled by default in Ubuntu". Interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn how to fix the problem that there is no sound when HDMI is enabled by default in Ubuntu.

Sound problems are a clich é in Ubuntu. I've written about a number of ways to fix the "silent" problem in Ubuntu, but the sound issue I'm going to talk about here is different from what I mentioned in another article.

So I installed Ubuntu 14.04, which is actually a reinstallation. As always, I did everything I had to do after installing Ubuntu 14.04 all over again. Then I realized that the system suddenly lost its voice. When I was investigating the problem, I found a strange thing. I checked the alsamixer and found that its condition was a little strange.

As you can see, HDMI is set by default in alsamixer. This means that HDMI output will be used by default instead of built-in speakers. This is why I can't get sound from the built-in speakers on the system.

Use the following command to check the status of alsamixer:

Alsamixer

If alsamixer is set to HDMI or other sound output by default, read on and see how we can fix this problem.

Fixed loss of voice in Ubuntu when the default setting was HDMI

Now let's force Ubuntu to replace the default HDMI with analog output, but we need a little more information. Open the terminal and use the following command:

Aplay-l

This will list the equipment, card number and so on. Note that check down the card and device number used in the analog output. My output is as follows:

Once you have the required card and device number, rebuild a profile:

Sudo gedit / etc/asound.conf

The above command also opens the file, adding the following two lines, and of course replacing the card and device number with your own:

Defaults.pcm.card 1defaults.pcm.device 0

Save the file and restart your computer. By now, you must have heard something. It's worth mentioning that this works for all Linux distributions, such as Linux Mint,Elementary OS,Fedora,Arch Linux, and so on. As I said before, this "aphasia therapy" is only for situations where HDMI is set as the default device.

At this point, I believe you have a deeper understanding of "how to fix the problem of no sound after HDMI is enabled by default in Ubuntu". You might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
