Try this, it helped a lot on my X1 Yoga G4: first install alsa-tools # apt install alsa-tools then run # sudo hda-verb /dev/snd/hwC0D0 0x17 SET_CONNECT_SEL 1 borrowed from here https://gist.github.com/hamidzr/dd81e429dc86f4327ded7a2030e7d7d9#gistcomment-3335436
I have absolutely no clue of how this works, and I hope there will be a better "official" fix soon, also because it's still just two channels, and volume cannot really be properly adjusted. However sound went from "crap" to "pretty decent". Needs to be run after reboot (and probably suspend). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1872108 Title: Bass not on working Lenovo ThinkPad X1 Carbon 7th gen running focal To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-ucm-conf/+bug/1872108/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
