I have a relatively new build that I can't seem to get audio to work on.

I have one card that i can see with pacmd list-cards:

1 card(s) available.
    index: 0
        name: <alsa_card.pci-0000_00_1f.3>
        driver: <module-alsa-card.c>

It lists a couple sinks:

    alsa_output.pci-0000_00_1f.3.analog-stereo/#0: Built-in Audio Analog Stereo
    alsa_output.pci-0000_00_1f.3.iec958-stereo/#4: Built-in Audio Digital Stereo (IEC958)

And can see that my headphones are connected:

    analog-input-front-mic: Front Microphone (priority 8500, latency offset 0 usec, available: no)
            device.icon_name = "audio-input-microphone"
    analog-input-rear-mic: Rear Microphone (priority 8200, latency offset 0 usec, available: no)
            device.icon_name = "audio-input-microphone"
    analog-input-linein: Line In (priority 8100, latency offset 0 usec, available: no)

    analog-output-lineout: Line Out (priority 9900, latency offset 0 usec, available: no)

    analog-output-headphones: Headphones (priority 9000, latency offset 0 usec, available: yes)
            device.icon_name = "audio-headphones"
    iec958-stereo-output: Digital Output (S/PDIF) (priority 0, latency offset 0 usec, available: unknown)

My problem is that any program that uses the analog-stereo output (from youtube to RhythmBox) blocks if i have it output audio to analog-stereo. I get no sounds and the program won't even run. If i switch the application to use iec958-stereo it will run and i can see the volume bars move in pavucontrol but since the only port for that output is S/PDIF I don't hear anything with my headphones.


I turned off pulse as described below. I then used alsamixer to turn all the channels up. I can hear white noise through the headphones which gets much quieter if I mute the front and rear mics. However, still no sound from the applications (though they don't block). In case it matters I have a Realtek ALC1150 chip.


Since it really seems like a driver issue and who knows how long that will take to get worked out, I picked up one of these for ~$35. Dropped it in and it worked first boot.


You could try to check if the problem is with PulseAudio or not, by disabling it temporarily in configs and instead enabling Alsa's mixer thingie.

  1. Disable PulseAudio:

    echo autospawn=no > ~/.pulse/client.conf
    pulseaudio -k
  2. Enable dmix, Alsa's native mixer:

    sudo gedit ~/.asoundrc

    to open the .asoundrc config file, and then paste:

    pcm.!default {
        type plug
        slave.pcm "dmixer"
    pcm.dmixer  {
        type dmix
        ipc_key 1024
        slave {
        pcm "hw:1,0"
        period_time 0
        period_size 1024
        buffer_size 4096
        rate 44100
    bindings {
        0 0
        1 1
    ctl.dmixer {
    type hw
    card 0

    reboot your computer and see if sound works. If it works, it's a problem with PulseAudio, if it doesn't (even with for example Youtube, or with VLC player when tried with all sound output options), it's most likely a driver or hardware problem. If it works and you can't figure out what was wrong with PA, you may want to keep it like that, I used that setting (slightly modified) for over a year and the only program I tried that has problems with it is Skype.

To reverse the effects simply delete the ~/.pulse/client.conf and ~/.asoundrc files and reboot.
