First check should be to make sure your install has sound drivers installed.
Run
inxi -Axxx
to check specifically for your computer's audio information.Audio:
Device-1: Intel 6 Series/C200 Series Family High Definition Audio vendor: Hewlett-Packard
driver: snd_hda_intel v: kernel bus ID: 00:1b.0 chip ID: 8086:1c20
Sound Server: ALSA v: k5.4.0-91-generic
While
snd_hda_intel
is the most common, your system may use different drivers.If your system is missing drivers, you may need to install a newer kernel series to get the drivers.
Next check is to install pavucontrol as the Linux Mint release notes advise:
Check to see if adjustments there help you gain sound output. This older reference How to Use PulseAudio to Manage Sounds on Ubuntu 18.04 has screenshots and explains some of the functionality available in PulseAudio.If you're facing issues with your microphone or your sound output, please install "pavucontrol".
This will add "PulseAudio Volume Control" to your menu. This application has more configuration options than the default volume control.
