On a different machine (no Nvidia) but with the same monitor, I can also reproduce this over DisplayPort but not over HDMI.
So I don't think that the Nvidia graphics card/driver is to blame. Instead, it seems like there's a general DisplayPort-related issue either in Linux/Alsa or in my cable/monitor (but if so, then Windows has a workaround for that issue, which could hopefully be implemented in Linux/Alsa too). Either way, it seems like this is something for the Alsa team to debug, and I'm happy to provide more information or run more experiments/tests. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1924846 Title: [550-254ng, Nvidia GPU 60 HDMI/DP, Digital Out, DisplayPort] Crackling sound during quiet parts of video, with DisplayPort only To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1924846/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
