    Antix 16.2 64 bit, recently reinstalled so this system starts with zero updates, zero additions. Audio works fine.

    Ran synaptic, refreshed, using stretch repositories.

    Marked all updates, applied, and sat back listening to music from Youtube.

    Part way through the update, about 30% done, audio shuts off.

    Seems like the only audio related update was Alsa.

    Removed the following packages:

    consider: soup-to-nuts inline lists like this will add noise to search results !

    The result of the matter seems to be that Alsa switched my sound device. I have been using audio through the Realtek ALC662 onboard 5.1 sound system, but Alsa has decided to use the ATI DVI interface of my add in graphics card that I’m using. Somewhere, nothing asked the user what to do, but in any event, I would like to reconfigure this.

    https://www.antixforum.com/forums/topic/lost-audio-output-help/ discusses a muting problem, my audio is not muted.

    $ cat /proc/asound/car*/co* | grep Codec
    Codec: Realtek ALC662 rev1
    Codec: ATI R6xx HDMI`

    System has the correct codec for the ALC662.

    $ inxi -A
    Audio:     Card-1 Advanced Micro Devices [AMD/ATI] RV710/730 HDMI Audio [Radeon HD 4000 series]
               driver: snd_hda_intel
               Card-2 NVIDIA MCP61 High Definition Audio driver: snd_hda_intel
               Sound: Advanced Linux Sound Architecture v: k4.4.10-antix.1-amd64-smp
    mmmmna@Reantix64b162:~

    I think the correct card is card-2, since I’m using the nVidia sound which the system chipset provides. I’m supposing the Realtek ALC662 is just a driver family which nVidia system chipset uses.

    Looking for suggestions of what to run to select and configure the proper card.

    Did you try in antiX Control Center under hardware to choose the default soundcard ?

    If this doesn’t help,you can look in soundsystem, if anything is muted.
    If this all doesn’t help, please post the output of
    aplay /usr/share/sounds/alsa/Front_Center.wav

    Control Centre -Hardware -Set Default Sound Card was correctly set to the nVidia sound card. Testing the sound produced a message that the Test Failed (could not connect to the selected device) Do I want to set the card again? I repeated the test, and the result was the same error message.

    Posted above, rechecked, still nothing muted.

    aplay /usr/share/sounds/alsa/Front_Center.wav

    Don’t use sudo, just aplay /usr/share/sounds/alsa/Front_Center.wav

    You could also try this.

    If you have asoundrc or asound.conf in etc (they may be hidden) delete them. Do the same if you have them in your home user directory.
    Then run alsamixer again

    I think there is a good chance that this combination of playing via ALSA while installing ALSA updates

    Before doing anything more drastic try the following:
    Stop ALSA
    sudo service alsa-utils stop

    Delete .alsaequal.bin. It is a hidden file in your home directory and will be automatically recreated when you get ALSA working again.
    rm ~/.alsaequal.bin

    Start ALSA
    sudo service alsa-utils start

    Make sure everything is not muted and the volume is turned up

    Play a test file

    Ran alsamixer, all volumes up, nothing muted, no sound, but when I raised volume for Front Mic, the speakers raised volume of a hissing sound.

    Moving to what SamK suggested:

    $ sudo service alsa-utils stop
    [ ok ] Shutting down ALSA...done.
    mmmmna@Reantix64b162:~
    $ rm ~/.alsaequal.bin

    Worked perfectly, thanks to everyone!
