I'm affected by this bug, and I can confirm that the root cause is a misconfiguration of kernel flags as described in this mailing list: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=976791#35
I've used the ubuntu wiki Build Your Own kernel guide (https://wiki.ubuntu.com/Kernel/BuildYourOwnKernel) to enable the CONFIG_SND_SOC_INTEL_USER_FRIENDLY_LONG_NAMES=y option, and I can confirm it works. Is there any chance that we can get the configuration options into the Ubuntu builds as follows? CONFIG_SND_SOC_INTEL_USER_FRIENDLY_LONG_NAMES=y CONFIG_SND_SOC_INTEL_SOUNDWIRE_SOF_MACH=m Seems like debian has already fixed this misconfiguration. ** Bug watch added: Debian Bug tracker #976791 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=976791 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1924685 Title: No sound output/input available after installing 21.04 To manage notifications about this bug go to: https://bugs.launchpad.net/oem-priority/+bug/1924685/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
