Re: No Audio after suspend on Lenovo Ideapad 130s Debian Buster

Here is the output when it is working:

aplay -l
**** List of PLAYBACK Hardware Devices ****

And here it is when it isn't working:

~$ aplay -l

Subdevice #0: subdevice #0

card 0: PCH [HDA Intel PCH], device 0: ALC269VC Analog [ALC269VC Analog]
Subdevices: 1/1

I notice when it's working the first entry says "Subdevices: 1/1" but after I suspended the machine it says "Subdevices: 0/1"

Also after I bring it up from suspend I notice when I use the hotkeys to adjust the volume it goes from the internal speakers to headphones. If I plug headphones in I also don't have any audio either. Any suggestions on what I should do now? Thank you for the response so far!

Regards,

John

If you are not running the latest alsa drivers you should first try to
upgrade them. Just to make sure the problem is not there.
Could you provide out `aplay -l` when you have sound and when you dont?
