            Bug ID: 253744
           Summary: ThinkPad E490 - sound/audio only works after specific
                    boot (from poweroff, not any connected plug)
           Product: Base System
           Version: 13.0-STABLE
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: kern
          Assignee: bugs at FreeBSD.org
          Reporter: nilsjohannsen at gmx.de

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.

See https://gist.github.com/NealsJoe/c940299c2b362381d254b34496ec1d66
These files on gist are from the system, sndstat, dmesg, sysctl I grabbed with
the script below

Code:

#!/bin/sh

doas cat /dev/sndstat > sndstat.txt

doas pciconf -lv | grep -i audio -B2 > sound-pciconf.txt
doas dmesg | grep -e 'sound' -e 'audio' -e 'snd' -e 'pcm' -e 'hda' >
sound-dmesg.txt
doas sysctl -a | grep -e 'sound' -e 'audio' -e 'snd' -e 'pcm' -e 'hda' >
sound-sysctl.txt

doas sysctl dev.pcm > sound-sysctl-pcm.txt
doas sysctl dev.hdaa > sound-sysctl-hdaa.txt
doas sysctl dev.hdac > sound-sysctl-hdac.txt
doas sysctl dev.hdacc > sound-sysctl-hdacc.txt
doas sysctl hw.snd > sound-sysctl-snd.txt

In the FreeBSD Forums I already discussed this issue with others, having the
same issue.

Thanks in advance, Neals
