https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=263385 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: firstname.lastname@example.org Created attachment 233292 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=233292&action=edit Output of /dev/sndstat I am having sound pops on an Asus PRIME Z690-P WIFI using a i9 12900KF CPU. 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 card. If I am playing a video through a web browser and scroll fast in another tab or window I get pops that coincide with my scrolling. Also if I probe the video 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/quick 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=896, old=896 delta=0 amt=0 ready=2048 free=0 kernel: pcm4: WARNING: PCMDIR_PLAY DMA completion too fast/slow ! hwptr=1152, old=1152 delta=0 amt=0 ready=2048 free=0 kernel: pcm4: WARNING: PCMDIR_PLAY DMA completion too fast/slow ! hwptr=256, old=256 delta=0 amt=0 ready=2048 free=0 Attached is output from /dev/sndstat Thank you. -- You are receiving this mail because: You are the assignee for the bug.
