I can't recall and have since switched to NixOS 21.03pre260232.733e537a8ad (Okapi), where I do not experience the sound issue on kernel version 5.4.85.
However, the wifi driver on Ubuntu that started showing extremely severe instability at roughly the same time as this sound underrun issue hit (https://bugs.launchpad.net/bugs/1908106) is very much still a problem on that version of NixOS (kernel 5.4.85), as well as every regression I tested it on, including every major version from 19.03 to 21.03. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1908153 Title: [Alienware 15 R4, Realtek ALC3266, Black Headphone Out or internal speakers] Underruns, dropouts or crackling sound To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1908153/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
