Sometimes “un-muting” the device in
alsamixer can restore audio. It’s so easy to try, it’s always worth a shot.

Headphones not being detected

You may want to take a peak in 'alsamixer' in terminal. Worth a shot. Sometimes all that is needed is to "un-mute" the headphones in alsamixer. In terminal type alsamixer Hit F6 and choose your AMD card with PCH in the name. It will not be the HDMI. You should now see many sliders, including headphones. Make sure this slider is un-muted and turned up. Worth a shot. Saved me many times.
