Hello, I have recently begun noticing relatively frequent sound cracks when watching youtube videos (firefox-39.0-8.fc22.x86_64, flash-plugin-11.2.202.491-release.x86_64 - this is on Fedora 22). Pulseaudio verbose output seems to show underrun when this happens: I: [alsa-sink-ALC892 Analog] alsa-sink.c: Underrun! I: [alsa-sink-ALC892 Analog] alsa-sink.c: Increasing minimal latency to 2,00 ms D: [alsa-sink-ALC892 Analog] alsa-sink.c: Latency set to 20,00ms D: [alsa-sink-ALC892 Analog] alsa-sink.c: hwbuf_unused=349272 D: [alsa-sink-ALC892 Analog] alsa-sink.c: setting avail_min=87760 D: [alsa-sink-ALC892 Analog] alsa-sink.c: Latency set to 20,00ms D: [alsa-sink-ALC892 Analog] alsa-sink.c: hwbuf_unused=349272 D: [alsa-sink-ALC892 Analog] alsa-sink.c: setting avail_min=87760 I: [alsa-sink-ALC892 Analog] alsa-sink.c: Scheduling delay of 13,85 ms > 10,00 ms, you might want to investigate this to improve latency... Is there anything I could do to stop these from happening, respectively investigate where the issue is coming from? It seems it is relatively recent. Best regards, Julian
