https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D263385 Bug ID: 263385 Summary: Sound pops using Realtek ALC897 Intel Alder Lake. Product: Base System Version: 13.1-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: verm@darkbeer.org Created attachment 233292 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D233292&action= =3Dedit Output of /dev/sndstat I am having sound pops on an Asus PRIME Z690-P WIFI using a i9 12900KF CPU.= =20 The sound hardware is an ALC897. Video card is an NVIDIA 3060. I get frequent audio pops that seems to somehow be related to the video car= d.=20 If I am playing a video through a web browser and scroll fast in another ta= b or window I get pops that coincide with my scrolling. Also if I probe the vid= eo card say with 'vdpauinfo' it will do it as well. There are no sounds when audio is not playing. I'm exporting the audio via Optical (ch6) to an external amp. This does happen with headphones directly connected to the back audio port (ch4) as well. It's most noticeable playing through Firefox while being extremely faint/qu= ick playing the same video downloaded with mpv. With hw.snd.verbose set to 4 I get these messages on my console: kernel: pcm4: WARNING: PCMDIR_PLAY DMA completion too fast/slow ! hwptr= =3D896, old=3D896 delta=3D0 amt=3D0 ready=3D2048 free=3D0 kernel: pcm4: WARNING: PCMDIR_PLAY DMA completion too fast/slow ! hwptr= =3D1152, old=3D1152 delta=3D0 amt=3D0 ready=3D2048 free=3D0 kernel: pcm4: WARNING: PCMDIR_PLAY DMA completion too fast/slow ! hwptr= =3D256, old=3D256 delta=3D0 amt=3D0 ready=3D2048 free=3D0 Attached is output from /dev/sndstat Thank you. --=20 You are receiving this mail because: You are the assignee for the bug.=
