Dummy Output in audio (SOLVED)

I'm not exactly sure what caused it.
I messed around a little with asound.conf, and even though I left it exactly how it was before, I'm almost sure it was because of this. I also updated my system, and since I only noticed there was something wrong with the output after the update, I have my suspicions it might have been this.

I checked the wiki and

# fuser -v /dev/snd/*

has no output.

I am really noob so I don't know what to do now.

Re: Dummy Output in audio (SOLVED)

Welcome to the boards

Post your asound.conf then. Also in case this is unclear you have to run that fuser command as root (as indicated by the # as opposed to a $) if you ran that as your user your result might not reflect reality.

Where do you get the dummy output? in some pulse mixer? What do you get for

systemctl --user mask pulseaudio.socket
systemctl --user stop pulseaudio
pulseaudio -vvv

Re: Dummy Output in audio (SOLVED)

asound.conf

# Use PulseAudio by default
pcm.!default {
  type pulse
  fallback "sysdefault"
  hint {
    show on
    description "Default ALSA Output (currently PulseAudio Sound Server)"
  }
}

ctl.!default {
  type pulse
  fallback "sysdefault"
}

# vim:set ft=alsaconf:

I ran fuser as root.

The dummy output is in the sound settings (I'm using cinnamon). My computer is not producing any sound

After

systemctl --user mask pulseaudio.socket
systemctl --user stop pulseaudio
pulseaudio -vvv

I still have Dummy Output. The output for pulseaudio -vvv is

Re: Dummy Output in audio (SOLVED)

So something is still broken in your /etc/asound.conf, can't put my finger on it, how did you edit it? Maybe you introduced windows line endings. Either remove the file and reinstall pulseaudio-alsa or

sudo sed -i 's/\r//g' /etc/asound.conf
systemctl --user unmask pulseaudio.socket #Restore pulse auto starting

Re: Dummy Output in audio (SOLVED)

Well, I deleted /etc/asound.conf , recreated it, rewrote it on terminal, and did

systemctl --user mask pulseaudio.socket
systemctl --user stop pulseaudio
pulseaudio -vvv

Now I have sound again and it detects my headphones so I guess it's solved.

I'm wondering, though, why I wrote it in windows line endings in the first place. I edited with a basic notepad. It's not the first time I write something and it's not recognized (not sure if it's always windows line endings), not only in the system, but in other programs as well. It doesn't happen always so it's a mystery to me. But I guess the initial problem is solved.
