Opening a browser shuts off audio

So the problem only happens with firefox? cleanup its profile: about:support

Thanks. It also happens with Chrome, but I don’t use that generally. Is there any particular field I should look for?

(I’ll post the about:support tomorrow morning, when back at the laptop)

Look for a file called asound.conf

Also check with pavucontrol if a sink is created when playing audio in firefox. If not then check if the service is running:

systemctl status --user pulseaudio

So, I tried to use Spotify, then turn on Firefox, then pause Spotify without playing audio in Firefox. Shortly after I paused Spotify, audio shut down, which means it was having Firefox open, rather than playing audio in Firefox, that was triggering the issue

Here’'s Firefox’s about:support

When I later try to play audio in Firefox, a sink is created in pavucontrol:

Is there any other information that could be of use? What should I do?

If a system is using software sound server PulseAudio, changing ALSA configuration /etc/asound.conf or creating custom user configuration .asoundrc should not be necessary

ALSA configuration to use PulseAudio as default sound server is usually provided by package pulseaudio-alsa with file /usr/share/alsa/alsa.conf.d/99-pulseaudio-default.conf:

# Default to PulseAudio

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

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

I suggest you remove file ~/.asoundrc to allow pulseaudio-alsa configuration

When I later try to play audio in Firefox, a sink is created in pavucontrol:

Check what audio sinks are available in pavucontrol Output Devices tab
or post more information about PulseAudio sinks in text format

pacmd list-sinks

It might also help to check audio stream information from Firefox and Spotify

pacmd list-sink-inputs

So, I installed some updates (network manager &c), and tried to play audio simultaneously on Spotify and Firefox, and it worked (I don’t know if this is a temporary thing, for example, the possibility that if I pause for long enough, the error will re-emerge; so far, though, my attempts to pause one and play the other for a while, or pause both, have not caused any problems like they used to). My /usr/share/alsa/alsa.conf.d/99-pulseaudio-default.conf is as you shared, @nikgnomic. After posting this, I will move .asoundrc to a different file, and I’ll update upon reboot.

Now that audio is playing, my output devices tab looks like this (when it doesn’t work, the bar below the volume meter is always empty)

The problem re-emerged without a clear trigger; I had Firefox open (but wasn’t playing audio through it), then paused Spotify, then the error returned (the sign of this being that the headphones suddenly appeared muted and with a low volume in pavucontrol, but unmuting and raising the volume did nothing to allow the audio to play; Spotify could not advance).
I have yet to reboot, so perhaps deleting .asoundrc would work.

I rebooted, opened Firefox, and the problem recurred; deleting .asoundrc didn’t solve it

Here’s the result of alsamixer -c 0 by the way. I don’t know the significance of this

Does it only happen with spotify? If so, then I assume a bug there, but then there is not much we can do. Contact the spotify support in this case.

you can try to restart pulseaudio when it happens:

systemctl restart --user pulseaudio.service

It also happens with VLC; with Firefox open, the audio shuts off, but the video can still advance

Did you already create a new user account and tested it there?

sudo useradd -m testuser
sudo passwd testuser
sudo userdel -r testuser

Not yet; I 'll do so today, after seeing if restarting PulseAudio works

Somehow, restarting PulseAudio a number of times got it to work. I’m not sure how.

I’ll update this thread in the future if the error recurs, or if this doesn’t fix it in future sessions.

The problem recurs after pausing; restarting PulseAudio, closing the audio-playing windows (Firefox tabs, Spotify &c) and starting it again allows one to hear something; older windows can’t continue to play.

I am having a similar problem with pulseaudio but I can get it to work usually by changing the Configuration from Analog Stereo to Digital stereo and back. I don’t know what that works, but it’s still pretty annoying. When this happens pacmd says suspend cause: APPLICATION

I’m using vanilla arch, might try a new profile as a troubleshooting step.

edit: i think this fixed it for me: i had an asound.conf file in /etc that i just renamed to asound.conf.old forgot i had done that at one point when I was trying to ditch pulseaudio. After doing that and rebooting, everything seems to work without having to change the configuration in pavucontrol!

This just occurred to me upon reading the most recent response: I have a file /usr/share/alsa/alsa.conf.d/99-pulseaudio-default.conf with the contents that you’ve listed, but I also have 50-pulseaudio.conf, whose contents are:

# Add a specific named PulseAudio pcm and ctl (typically useful for testing)

pcm.pulse {
	@args [ DEVICE ]
	@args.DEVICE {
		type string
		default ""
	}
	type pulse
	device $DEVICE
	hint {
		show {
			@func refer
			name defaults.namehint.basic
		}
		description "PulseAudio Sound Server"
	}
}

ctl.pulse {
	@args [ DEVICE ]
	@args.DEVICE {
		type string
		default ""
	}
	type pulse
	device $DEVICE
}

as well as 99-pipewire-default.conf:

pcm.!default {
    type pipewire
    playback_node "-1"
    capture_node  "-1"
    hint {
        show on
        description "Default ALSA Output (currently PipeWire Media Server)"
    }
}

ctl.!default {
    type pipewire
}

and 50-pipewire.conf:

# Add a specific named PipeWire pcm

defaults.pipewire.server "pipewire-0"
defaults.pipewire.node "-1"
defaults.pipewire.exclusive false
defaults.pipewire.role ""

pcm.pipewire {
	@args [ SERVER NODE EXCLUSIVE ROLE ]
	@args.SERVER {

	@args.EXCLUSIVE {

			name defaults.pipewire.exclusive
		}
	}
	@args.ROLE {
		type string
		default {
			@func refer
			name defaults.pipewire.role
		}
	}


	type pipewire
	server $SERVER
	playback_node $NODE
	capture_node $NODE
	exclusive $EXCLUSIVE
	role $ROLE
	hint {
		show on
		description "PipeWire Sound Server"
	}
}

ctl.pipewire {
        @args.SERVER {
                type string
                default {
                        @func refer
                        name defaults.pipewire.server
                }
        }
        type pipewire
        server $SERVER
}

Is this at all significant or helpful?

Update: switching to Pipewire seems to have fixed the problem in toto.
