Hi all together and a happy new year!
I am struggling already since several months with the sound/audio on my Lenovo ThinkPad E490. Because I am trying to find the cause since several weeks now, I hope to find some suggestions and help here.
If I boot the notebook after power off, without anything connected, no power supply, no headphone connected in the audio jack and the sound works. It is possible to switch between the notebook sound (pcm0) and the headphone (pcm1) without any issue.
But after a reboot, if anything is connected as e.g. the power supply on the USB-C connector and/or some headphone on the audio jack the notebook makes some very strange and loud noises while booting and after boot I am not able to get notebook to make any noise or sound on any output.
- FreeBSD 12.2-RELEASE-p1 GENERIC amd64
- Latest HW-Probe: https://bsd-hardware.info/?probe=1ffaf5420c
These files on gist are from the system, sndstat, dmesg, sysctl I grabbed with the script below: https://gist.github.com/NealsJoe/c940299c2b362381d254b34496ec1d66
Has anybody a clue why the sound does not work if the notebook boots with external connections? An issue of hardware or software? Is it related to the power supply mass connection whose differs in case the power supply is connected?
Any hints are welcome. ;-)
Thanks in advance, Neals
