Ubuntu – Ubuntu 16.04 Front Panel audio does not work

16.04alsasound

On my desktop running Ubuntu 16.04 I can have audio on the speakers connected n the read but I do not have audio on my headphones.

Further investigation has shown that somehow the front panel audio is muted by default whilst the speakers are not.

Type alsamixer to the terminal and using left and right arrow keys in to the Headphones selection if is muted (shows MM on above) press M to unmute and press the up arrow to volume up

Afterwards insert the following command to the terminal:

alsactl --file ~/.config/asound.state store

To store the settings into a file to your home folder. Then in order to restore it every time you login (is the best option I've tried) use this command:

echo "alsactl --file ~/.config/asound.state restore" >> ~/.bashrc

Update

Also the source of the problem, in my case is that the Front Panel uses AC'97 instead of IntelHD one, so setting the appropriate setting into BIOS settings also fixed the problem whithout the need to do the following fix above.

So have a look first whether your motherboards Supports the older AC'97 format as well alongside with IntelHD, especially if you custom-built your desktop computer.

What helped for me was to run alsamixer with headphones in. Then moving right to the column marked "Auto-Mute mode" and pressing down to disable it.

Headphones then worked.

I also ran sudo alsactl store for good luck.

Seems to have worked.

Ubuntu – Kubuntu 20.04 – front panel audio jacks “unplugged” and Analog Stereo Duplex profile “unavailable”

This is really a workaround to make changes in pavucontrol GUI permanent rather than correct jacks appearing as "unplugged" and profiles as "unavailable". I thought I could share it in case someone bumps into similar problems and it is maybe too large for a comment.

PulseAudio has a command-line interface that is documented in man pulse-cli-syntax (which I found here). These commands may be tested in pacmd (which I found here). Using this documentation and pacmd's help, I found that the two commands I needed to reproduce my changes in pavucontrol are

set-card-profile 1 output:analog-stereo+input:analog-stereo
set-sink-port 0 analog-output-headphones

Then, to make these changes permanent, one can change ~/.config/pulse/default.pa (a list of related configuration files is shown in man pulse-cli-syntax). Here, I appended the following:

### Set Built-in Audio (HDA Intel) profile to Analog Stereo Duplex
set-card-profile 1 output:analog-stereo+input:analog-stereo

### Set Built-in Analog Stereo port to Headphones
set-sink-port 0 analog-output-headphones

Finally, pulseaudio -k restarts the sound server and confirms that these two changes apply. The same should happen at restart.
