Audio does not work (it works if I use headphones)

The fact that pavucontrol allows me to use headphones makes me think that the audio hardware works.

However I can't get the speaker work.

The ALSA wiki page says that manual installation is not necessary, so I just installed `alsa-utils` to have alsamixer and amixer, and `pulseaudio` and `pavucontrol`.

I hear no audio, however. So I tried unmuting the channels, but `amixer sset Speaker unmute` gives `amixer: Mixer attach default error: No such file or directory`, and similarly `alsamixer` gives `cannot open mixer: No such file or directory`.

I have the feeling I just miss some package.

Re: Audio does not work (it works if I use headphones)

The suggestion of installing `sof-firmware` I found here for my Dell Vostro 5590 made the audio work.

Well, not really. I'm just going crazy with all these pulseaudio/alsamixer/amixer/pavucontrol and all of that. That stuff is just what undefined behavior actually is hmm

Re: Audio does not work (it works if I use headphones)

If you use pulseaudio you should use pulseaudio tools first to try to fix this, ALSA is below that.
pavucontrol is such a tool (often shows up as "Mixer" only in your DE). It has lots of settings, some of them half hidden. Try if you can't at least get a better grasp at the situation with that.
If that doesn't help you should use pulseaudio command line tools to provide some troubleshooting info.
I probably don't need to tell you that the archwiki has a pulseaudio page. With a dedicated troubleshooting sub-page: https://wiki.archlinux.org/index.php/Pu … leshooting


However studied and stilted your rant, it can never hide the base and primitve emotion that inspired it.

Re: Audio does not work (it works if I use headphones)

Ok, it turns out I was mislead by the volume controller of the headphone. Even without the headphones connected, but only with the volume controller connected, I could push its + button and the audio was becoming audible, but using the laptop keyboard's volume up didn't have the same effect. The thing is, for some reason the latter took much longer to reach audible volume percentage from starting from 0%.

In the meanwhile I have unistalled pavucontrol, pulseaudio, pulsemixer, as I want to understand a bit better what each piece of audio-related software is for. I'm going to uninstall sof-firmware to see if that is actually needed or not.

Re: Audio does not work (it works if I use headphones)

I'm still not happy with how the audio works, because it does not interact well with my i3blocks blocklet for audio control, which I really need to use to change audio from speaker to headphones (but not only) without having to open pavucontrol everytime, and if I don't understand what pavucontrol is telling me, I can certainly not figure out how to fix these things.

So to start out, what are these 3 entries here? Only the one which is selected makes me hear the sound.

Re: Audio does not work (it works if I use headphones)

They are the devices for hdmi, i.e. if you had external monitors connected you could route audio through them, this is entirely normal and expected. I'm not quite sure what your remaining problem is? It sounds like your headset/microphone has a separate hardware internal volume control, if that is the case you can't really influence that from the OS.

Maybe instead of  being confused by UI controls, you might want to check or post how the general state looks like, so the outputs of

amixer -c0
pacmd list-cards
pacmd list-sinks

can help us to get an overview of how your general state looks like.

FWIW sof-firmware and how it handles and allocates audio controls is quite a new and different concept from how it used to work and the things surrounding this are currently quite WIP. Pulseaudio 14 should have some better handling of the logic sof cards use.

Re: Audio does not work (it works if I use headphones)

Then probably I just need to investigate how the audio blocklet in i3blocks interacts with the devices, as at the moment it it moves to those hdmi things, which means no sound, if there's nothing connected to the HDMI.

However, the outputs of those commands are:

Re: Audio does not work (it works if I use headphones)

No I did mean pacmd list-sinks, for the level we are interested in the sinks are important, sink-inputs are the actual clients they are only interesting in the  context that they play to the correct sink, but we need some sink information to know whether things are set up correctly here.

E.g. if your configured default sink is a hdmi device by accident then it's no surprise that new clients (applications) start out on a HDMI sink. But this is usually something you have to configure once and it will be remembered in the future

Re: Audio does not work (it works if I use headphones)

From this output, at least from pulse's side, everything looks as expected/intended. So this might indeed be a strange behaviour of the i3bar plugin which I don't have any hands on experience with.

FWIW if you want to disable the HDMI devices entirely so that no misdetection/accidental usage of them happens you could edit  /usr/share/alsa/ucm2/sof-hda-dsp/HiFi.conf and  remove the last line including a HDMI configuration. That's a bit of a hack, and will likely get overriden on updates of the alsa-ucm-conf package unless you add the relevant file to the NoExtract directives or remember to do that readjustment again (... maybe they have evolved until then to make this generally more controllable)

Re: Audio does not work (it works if I use headphones)

V1del, I applied the hack you said, and I see the output of those commands change accordingly: no more HDMi entries there.

And so I'm all set in pulseaudio. I guess at the moment I will want to connect an HDMi monitor to this laptop and play the audio there, I'll have to undo this change, right?

This is also helping me understand what's wrong with the i3blocks blocklet which should govern the audio. If I correctly understood the script of the blocklet, when cliked the blocklet loops on the sinks listed by `pacmd list-sinks` (the doc reads "Left/right clicks change default playback device"), so it looks normal to me that it does not work well if headphones and speaker are listed under the same sink as different ports, as in my case.

So my questions is: what is the meaning of having headphones and speaker as different ports under the same sink? Aren't they two distinct sinks?
Well, another question is: how does the concept of "playback device" apply to this discussion? Is it a synonym for "sink", for "port", for something else, or for nothing at all?

Re: Audio does not work (it works if I use headphones)

Try setting-up an asoundrc file under you user. I suggest option 2.

pcm.!default {
  type plug
  slave {
    pcm "hw:1,0"
  }
}
ctl.!default {
  type hw
  card 1
}
pcm.dsp {
   type plug
   slave.pcm "intel"
}



SECOND OPTION - EITHER WILL WORK - use this option for multiplexing

defaults.pcm.card 1
defaults.pcm.device 0
defaults.ctl.card 1

Re: Audio does not work (it works if I use headphones)

@EndUseronly No, that won't help their particular problem at all.

@Enrico

Regarding your questions, ports are usually for devices where the relevant conditions are mutually exclusive (you can't play back different audio on headphone or speaker, they are logically linked, plugging in a headphone usually just mutes the speaker component but you can't play back something entirely different on just the speaker or just the headphones , they will receive the same audio signals),  sinks on the other hand are completely disjoint from each other And you could have program y play back from hdmi while program x plays back on your built in audio card (which is, depending on port setting, outputting to your speakers or your headphones).

A "playback device" is ultimately a sink yes. Sinks can take a few more specialised forms, but for normal usage and in default configuration you will have a sink per physical output audio card available on your system.
