No sound after sleep mode

Support
1

I have a Xioami notebook pro laptop on fresh Manjaro GNOME.

After the laptop goes in sleep/hibernate mode, there is no sound that comes out of the speakers. The system settings (settings>sounds) are detecting music is being played and the headphones are working fine after sleep. The issue is only related to the speakers integrated in the laptop. As a quick fix, I need to reboot to have the speakers to work again.

I tried to use method that I had found:

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

But nothing happens after any of this commands. Cursor just blinking, tab in terminal looks frozen. Output device in GNOME Settings changes to dummy output.

Additional hardware info:

$ aplay -l

For me disabling pipewire and restarting pulsaudio did the trick.

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

I also masked pipewire just to make sure.

@chromsky Thank you very much!

After disabling pipewire I added the restart audio script to /lib/systemd/system-sleep/99_restart_sound and now sound working after waking up.

#!/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

The file must be executable:

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

After disabling pipewire I didn’t have any issues with sound after sleep mode but I’ll keep your script in mind if the audio problems were to return.
