** Description changed: Software details: Distro: Kubuntu 20.04 Beta Kernel: 5.4.0-21-generic alsa-base version 1.0.25+dfsg-0ubuntu5 alsa-utils version 1.2.2-1ubuntu1 pulseaudio version 1:13.99.1-1ubuntu1 Hardware details: Motherboard: Gigabyte GA-AB350M-D3H Audio Codec: Realtek ALC887 GPU: Nvidia RTX 2060 Super (with the audio output disabled in PulseAudio) Regarding the issue: Every time I start an audio stream (regardless of the application), I can hear interruptions in the sound and when opening alsamixer I can also see the interface kind of flickering for a few milliseconds. After running pulseaudio with logging enabled for a few seconds (while playing music), this pattern can be seen: [pulseaudio] sink.c: alsa_output.pci-0000_0a_00.3.analog-stereo: state: IDLE -> RUNNING D: [pulseaudio] module-alsa-card.c: Jack 'Front Headphone Jack' is now plugged in D: [pulseaudio] device-port.c: Setting port analog-output-headphones to status yes D: [pulseaudio] module-alsa-card.c: Jack 'Front Headphone Jack' is now unplugged D: [pulseaudio] device-port.c: Setting port analog-output-headphones to status no D: [pulseaudio] module-alsa-card.c: Jack 'Front Headphone Jack' is now plugged in D: [pulseaudio] device-port.c: Setting port analog-output-headphones to status yes D: [pulseaudio] module-alsa-card.c: Jack 'Front Headphone Jack' is now unplugged D: [pulseaudio] device-port.c: Setting port analog-output-headphones to status no D: [pulseaudio] module-alsa-card.c: Jack 'Front Headphone Jack' is now plugged in D: [pulseaudio] device-port.c: Setting port analog-output-headphones to status yes D: [pulseaudio] module-alsa-card.c: Jack 'Front Headphone Jack' is now unplugged D: [pulseaudio] device-port.c: Setting port analog-output-headphones to status no D: [pulseaudio] module-alsa-card.c: Jack 'Front Headphone Jack' is now plugged in D: [pulseaudio] device-port.c: Setting port analog-output-headphones to status yes D: [pulseaudio] module-alsa-card.c: Jack 'Front Headphone Jack' is now unplugged D: [pulseaudio] device-port.c: Setting port analog-output-headphones to status no D: [pulseaudio] module-alsa-card.c: Jack 'Front Headphone Jack' is now plugged in D: [pulseaudio] device-port.c: Setting port analog-output-headphones to status yes D: [pulseaudio] module-alsa-card.c: Jack 'Front Headphone Jack' is now unplugged D: [pulseaudio] device-port.c: Setting port analog-output-headphones to status no D: [pulseaudio] module-alsa-card.c: Jack 'Front Headphone Jack' is now plugged in D: [pulseaudio] device-port.c: Setting port analog-output-headphones to status yes D: [pulseaudio] module-alsa-card.c: Jack 'Front Headphone Jack' is now unplugged D: [pulseaudio] device-port.c: Setting port analog-output-headphones to status no D: [pulseaudio] module-alsa-card.c: Jack 'Front Headphone Jack' is now plugged in D: [pulseaudio] device-port.c: Setting port analog-output-headphones to status yes D: [pulseaudio] module-alsa-card.c: Jack 'Front Headphone Jack' is now unplugged D: [pulseaudio] device-port.c: Setting port analog-output-headphones to status no D: [pulseaudio] module-alsa-card.c: Jack 'Front Headphone Jack' is now plugged in D: [pulseaudio] device-port.c: Setting port analog-output-headphones to status yes D: [pulseaudio] module-alsa-card.c: Jack 'Front Headphone Jack' is now unplugged D: [pulseaudio] device-port.c: Setting port analog-output-headphones to status no D: [pulseaudio] module-alsa-card.c: Jack 'Front Headphone Jack' is now plugged in D: [pulseaudio] device-port.c: Setting port analog-output-headphones to status yes D: [pulseaudio] module-alsa-card.c: Jack 'Front Headphone Jack' is now unplugged D: [pulseaudio] device-port.c: Setting port analog-output-headphones to status no D: [pulseaudio] module-alsa-card.c: Jack 'Front Headphone Jack' is now plugged in D: [pulseaudio] device-port.c: Setting port analog-output-headphones to status yes D: [pulseaudio] module-alsa-card.c: Jack 'Front Headphone Jack' is now unplugged D: [pulseaudio] device-port.c: Setting port analog-output-headphones to status no D: [pulseaudio] module-alsa-card.c: Jack 'Front Headphone Jack' is now plugged in D: [pulseaudio] device-port.c: Setting port analog-output-headphones to status yes Note: I've no headphones attached !
