Just wanted to add my own voice to this problem, running Windows 11 with the exact same issue.
I note that for me when windows starts if I hear a pop at the start of the Windows startup, then it's a good sign that audio is going to be a problem today.
Question for everyone: Are you all using Realtek sound controllers and drivers?
Things I have tried that don't fix it:
- Disabling Fast Start (it's still off but the problem persists - I double checked after reading above that someone had this turn back on.
- Installed latest updates.
- Rolled back my ASUS MB bios to previous version (this actually helped with a sleep crashing issue, but not the audio problem).
- Updating Windows audio drivers
- Rolling back Windows audio drivers
- Updating and rolling back ASUS/Realtek drivers
- Removing all signs of Sonic Studio
- Disabling DTS
- Disabling all other audio inputs and outputs that I don't use (but another bug in Windows causes these to come back from time to time - and the defaults to change - another problem featured in other threads)
- changing how I connect to the speakers (they are powered speakers with a built in DAC) - BT, optical, analogue
- Updating Windows
- All the other things listed above and in all those articles (outside of reinstalling Windows)
- Standing on one foot and rubbing my tummy while patting my head
I was about to buy a USB audio "card" but I see that someone else tried that.
One thing I am unsure about is why there are Realtek drivers from Microsoft for the Audio inputs and outputs section in Device Manager, and Realtek drivers under Sound, video and game controllers. I wonder if this driver mismatch is part of the issue?
Going to try reaching out to Realtek to see if they can help. It's one of those problems that is annoying enough to warrant spending time trying to fix it, but small enough to feel like such a waste of time doing so with no real answers from anyone who can actually understand what is going on software and/or hardware wise (I am 99% sure it's driver related).
