I have a laptop with Intel audio card that lspci reports as

00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 04)

It is responsible for both Analog Audio (speakers, 3.5 mm jack) and HDMI sound (since my laptop has HDMI output) as reported by aplay --list-devices

    **** List of PLAYBACK Hardware Devices ****
    card 0: PCH [HDA Intel PCH], device 0: ALC269VB Analog [ALC269VB Analog]
      Subdevices: 1/1
      Subdevice #0: subdevice #0
    card 0: PCH [HDA Intel PCH], device 3: HDMI 0 [HDMI 0]
      Subdevices: 1/1
      Subdevice #0: subdevice #0

Obviously the audio card is configured and drivers are loaded. Media players, however, don't produce any sound. pavucontrol shows that there is output from the player - under playback tab, the slider which acts as a visual feedback is "bouncing". But under "Output devices" tab, the very same slider doesn't react at all. Under Configuration tab "Profile" is set to "Analog Stereo Duplex", which it should be. If I change the profile to "Digital Stereo (HDMI) Output" the aferomentioned slider suddenly begins to bounce. It is now obvious to me that either ALSA or PulseAdio (I don't know which is to be blamed) recognize the HDMI chip as the default one. alsamixer gives me option to change sound card, but not it's chip.alsamixer interface

I solved the problem by adding the following code to /etc/asound.conf

pcm.custom
{
    type plug
    slave
    {
        pcm "dmix:0,0"
    }
}

pcm.!default pcm.custom
