Hi, some days ago i already privately reached out to Benjamin (of this Thread in #11). This was his answer:
Hi Martin, Thanks for getting in touch. As another user reported in this message https://gist.github.com/hamidzr/dd81e429dc86f4327ded7a2030e7d7d9#gistcomment-3276276 the patches that I originally posted introduce a regression in headphone output volume. I'm currently trying to see if that can be fixed. Today I tried fiddling with alsactl controls but that did not help. However I found that Node 0x21 (as well as Node 0x17) also has a different connection when using my patches. I'll investigate further about that as soon as I have some time. Until the headphone volume regression is avoided I don't think it would be a good idea to post the patches upstream again. I didn't look into the Ubuntu 20.04 situation but I'm curious to do that if I have the time. So it seems, they're on it. Don't know how much push we should put into this mailing list though. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to alsa-ucm-conf in Ubuntu. https://bugs.launchpad.net/bugs/1872108 Title: Bass not on working Lenovo ThinkPad X1 Carbon 7th gen running focal Status in alsa-ucm-conf package in Ubuntu: Confirmed Status in linux package in Ubuntu: Confirmed Bug description: Related to https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1845677/comments/14 Audio works and the volume seems reasonable however the audio is noticeably missing bass giving everything a high treble sound.
