Question MSI z690-a wifi DDR5 - Left speaker stops working after sleep

[johnjay522]

Hello,
My speakers work great in full 2.1 stereo when I start my computer, but once it goes into sleep mode, after it wakes up, only one speaker works (right) and I lose stereo sound. I have tried every audio port in the motherboard, I updated both the BIOS and the Realtek audio drivers to the latest versions, but nothing seems to work.
When I test the sound from both Windows and Realtek, only one speaker makes a sound, and then silence while the other is supposed to play the chime.
To return to full stereo, all I need to do is unplug the audio jack and plug it right back in to the same port and everything works fine again. Its not that big of a deal, but its annoying to have to do this every time the computer sleeps. Anyone have a solve for this?
Thank you!

There are several levels of power savings in sleep mode.
Your settings, likely the default one probably does not keep enough current to allow the sound to reactivate.
You may want to look into disabling the more aggressive C states

My speakers work great in full 2.1 stereo when I start my computer, but once it goes into sleep mode, after it wakes up, only one speaker works (right) and I lose stereo sound.

The fact that one channel (right) works fine implies the audio codec is working normally. If the codec was failing to restart after sleep, I'd expect no sound at all.

The right channel is the ring on a standard 3.5mm jack plug. The left channel is the tip. The ground or common connection for both channels is the sleeve.

The problem might be associated with poor electrical contact between the tip of your 3.5mm plug and both sockets in the computer (front and rear panel?), implying dodgy sockets. It's more likely though the fault is in the speaker plug.

If you have a pair of headphones with a 3.5mm plug, try them instead of the speakers. If the headphones are OK in both sockets, you've narrowed the fault down to the speakers.

Are the speakers passive or active? If they're passive and you've got a multimeter, set it to the Ohms range and check tip to sleeve and ring to sleeve. You should hear a click or pop from each speaker as you make and break the connection.

If there's any sign of an intermittent connection, chop the 3.5mm plug off the lead (if it's moulded) and solder a new one on. They're cheap as chips (mostly) and you might fix the fault.

If you can unscrew the back shell off the plug, check the connection to the tip. Inexpensive plugs are sometimes badly crimped and you may have a loose connection. If so, change the plug.

Some computers can detect what you've plugged into the audio sockets and set themselves up accordingly. Only experimentation will produce an answer.
