Having a similar issue on my ASUS Zenbook UX434, also using the ALC294 as above, Kernel: 5.13.0-28-generic.
In my case after a reboot from my Windows 10 dual boot the audio out is fine, but the microphone has very loud crackling which makes it unusable. The problem isn't fixed by a reboot but after a full shutdown and restart the problem seems to go away. Thanks to Hilikus for the workaround! Had an identical problem on Kubuntu 20.04 and now ZorinOS 16 - clearly this issue isn't entirely fixed even with more recent kernel patches. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1742852 Title: [hostname, Realtek ALC294, Speaker, Internal] No sound at all after windows update To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1742852/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
