Since a few updates, I noticed that whenever I wake up my system from sleep, the audio is muted for some reason.
This was not the case before and I think this is pretty annoying.
Anybody noticed the same? Is this a new “feature” or a regression?
I am on Manjaro Unstable and here are my system details:

Hi - I’m no expert on audio issues, but just to clarify the issue for folks - are you able to unmute as normal afterwards, or is the audio “stuck” muted until a reboot?
alsamixer is supposed to save your audio settings and restore them at reboot using the info in /var/lib/alsa/asound.state
check that this file is being updated when you change settings and that they are being restored when you reboot.
you can force it to save the state by running sudo alsactl store
i had issues on plasma 6.1 where it would not remember my sound state so i ended up adding sudo alsactl restore to my autostart

Ah right, I can always unmute it using the dedicated keys on my keyboard.
Okay thank you for the idea.
I have saved my current state with working/ unmuted sound, and will compare the file contents when this issue occurs again.
Strangely, it doesn’t seem to happen for every standby-wakeup cycle.
how are you controlling sleep states, thru the power management settings ( or energy savings, depending on how you access it)?
does this difference have anything to do with how long the system is in sleep state, as in less than 2hrs it remembers, but greater than 2hrs it forgets?
I had no issues.
I have some automated behaviour - suspend at 11pm after setting volume to 10%, then wake up at 5.58am, and at 6.05 set volume to 50%… no problems with that.
Normal sleep/wake has zero effect on volume.
NicGnomic is the Audio expert in the Manjaro forum, but as always, see if you can replicate this with a fresh USER - as it seems likely a USER data problem than a bug.

I usually just press the standby button in the start menu, but in the power management settings I have the standby-mode (?) set to “Standby, then hibernate”.
However, I just tested going to hibernate, and noticed that it doesn’t really work in general.
It seems like my PC is just shut down completely, because all my apps were closed when i turned it on again and i also had to log in through SDDM normally.
Anyway, it seems like some of the recent Manjaro updates fixed the problem automagically again.
After the last reboots/ standby cycles, the volume was on the correct level.
So i guess this is fixed already. If it pops up again, I will report it here.
If it appears again, I contact him, thanks for the hint.

hibernate is save to disk… so if you are not reloading from disk when you power back up after to goes into hibernate then you need to set up your swap partition so it has someplace to store the ram contents before the power goes off.
otherwise you are just sleeping and the power is still going to the ram to keep everything the way you left it.
this is why i asked, because if you are rebooting from scratch after hibernation, then that could explain why you came back to a muted audio instead of where you left it.
Hmm in theory, I have a swap partition:
swapon --show ✔
NAME TYPE SIZE USED PRIO
/dev/nvme0n1p3 partition 8,8G 0B -2
No idea, why hibernation still doesn’t work.
If i enter hibernation, it takes quite a while until the PC turns off, so I thought it must be saving the RAM’s content to the disk in that time, but seems like something is going wrong then.
I would have assumed that the system just stays active if it doesn’t work, or goes into standby instead, but that doesn’t seem to be the case.
do a blkid on that partition and put it into your grub file like so
# also important that the kernel knows where to find the stored image on disk so add this to grub
GRUB_CMDLINE_LINUX="resume=UUID=xxxx-xx-xxxxx-xxxx-xxxx-xxxxxxx"
don’t forget to run sudo update-grub
