reading how booting into Windows fixes the issue, my initial gut instinct is that it's a driver issue. Searching around led me:
https://github.com/thiagotei/linux-realtek-alc287/tree/main/lenovo- legion and eventually https://bugzilla.kernel.org/show_bug.cgi?id=208555#c294 which seems to point to possible firmware and kernel patches, as well as further issues over time. Could you try the steps in the first entry and see if it resolves issues? I'm also forwarding this on to kernel folks as they'll have a better idea on the kernel and firmware side. ** Bug watch added: Linux Kernel Bug Tracker #208555 https://bugzilla.kernel.org/show_bug.cgi?id=208555 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1984157 Title: [Lenovo Legion Y9000X IAH7 (82TF), Realtek ALC287, Speaker, Internal] No sound at all To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1984157/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
