I have some sound issues with my Panasonic CF-SZ6 notebook.
Upon upgrading from 15.2 -> 15.3 the headphone jack has become unreliable/non functioning.
With both 15.1 and 15.2, I was always able to plug in a headset into the 3.5" jack and the OS would automatically switch to the headphone output and mic input.
This is not the case anymore. If I plug in the same headset it won’t switch at all. Only if I go into alsamixer and manually unmute the headphone jack and mute the internal speakers, it works.
