I see the same behaviour: With headphones plugged in:
1/ In xfce4's panel plugin mixer: right-click -> select 'mute' -> xfce4-mixer shows Master & Headphone muted. (IIRC, with headphones not plugged in, Speaker & PCM are muted instead of Headphone.) -> unmuting through xfce4's panel plugin mixer only unmutes Master channel, leaving Headphone still muted. -> xfce4-mixer needs to be opened to unmute each muted channel 2/ In xfce4's panel plugin mixer: turn down volume "low enough" (not zero) -> volume suddenly drops to zero. -> xfce4-mixer shows Master, Headphone and PCM are set to volume zero. -> turning up the volume again through xfce4's panel plugin mixer only increases volume of Master channel, leaving Headphone & PCM at zero. -> again, xfce4-mixer needs to be opened to increase volume of Headphone & PCM channels. So the bugs are as follows: * Muting/unmuting and increasing/decreasing volume should act on the same channels, instead of being asymmetric. * Decreasing volume should be continuous, instead of suddenly dropping to zero below a certain threshold.
