Speakers stop working after sleep

Support
1

Hi,

I’ve been reading through the forum and saw a similar subject (cannot link it it seems), but the solutions given in it were not working for me.

I have a Xiaomi notebook laptop, and every time I wake it up from sleep, the speakers are not working anymore and I need to reboot it. Also only the speakers are not working, when i try plugin in my earbuds, everything works just fine.

I tried re-scanning like in shared thread :

$ sudo su -
$ echo 1 > /sys/bus/pci/devices/0000:00:1f.3/remove
$ echo 1 > /sys/bus/pci/rescan

And it only works if something plugged in the jack port (my earbuds for example), otherwise the speakers don’t start working again.

Hardware info (sorry for the french !) :

$ aplay -l

And like in the previously mentioned subject I tried these commands :

systemctl --user disable --now pipewire.socket
systemctl --user disable --now pipewire.service
systemctl --user restart pulseaudio.service

and adding this script in /lib/systemd/system-sleep/99_restart_sound :

#!/bin/sh
  
case "$1" in
    post)
        DEVICE_ID=`lspci -D |grep Audio|awk '{print $1}'`
        echo 1 > /sys/bus/pci/devices/${DEVICE_ID}/remove
        sleep 1
        echo 1 > /sys/bus/pci/rescan
esac

with :

sudo chmod +x /lib/systemd/system-sleep/99_restart_sound

But nothing worked so far, still no sound in my laptop’s speakers after waking up from sleep.
