Hello and welcome to the forum :)

For future reference, please read the information here. The more information we have, the better we can help you. ;)

If you would, please open a terminal and post the results of these commands...

Also, please post a screenshot (using the "Attach Files" feature below "Additional Options" underneath the "Reply to Thread" text field,) of the following command...

This will help give us a better idea of your hardware and, hopefully, why you're not receiving any sound.

You might not have the proper output enabled. You can install alsamixer and run it. There you can enable and disable the various outputs, and adjust the volume. Also, make sure the volume is not set to zero.

Make sure the user is in the audio group.

$ groups
$ id

Make sure alsa found a sound device. It might be disabled in the bios or not the default soundcard. Like if the webcam got index 0 which is an input only device in most cases.

$ cat /proc/asound/cards

The 0 one is the default in many cases. Make sure the audio is not muted.

$ alsamixer -c 0

Change 0 to index of the card you wish to use if applicable. Test the sound card.

$ speaker-test -c 2 -l 1 -D hw:0

This might be different if you're using pulseaudio or jackd by default.

$ mpv --ao=jack audiofile.wav
$ mpv --ao=pulse audiofile.wav

And various other routes to take. Last time that I used avlinux it was 32 bit only and fairly optimized for old hardware. If you're on new hardware with a soundcard that's new-ish, you might need a newer kernel for sound to properly work. I tend to use debian, it has all the same packages. Although not as out of the box as an avlinux install is on blessed hardware.
