seem jack detection problem as front headphone jack is plugged and unplugged at Nov 6:10:38:08
do your computer chassis has hda front audio panel ?

Sometimes it goes to mute. I watched System Settings > Sound and found that sound output device is alternating between 'Analog Output -Built-in Audio' and 'Headphones - Built-in Audio'. The switching is too frequent and introduces glitches in output. By default output device is 'Analog Output - Built-in Audio'.
