Clicking and popping audio in Windows 11 ARM on M1

I also have this problem. Macbook Pro 14 M1 Max 32 GB RAM. Even when I set the memory allocation for the Windows 11 VM to 4 gb the audio is still crackling. I need the audio of the VM to work flawless. Any help is appreciated.

 

Same issue here. What I don't understand about this reasoning is that the total memory required to run "sound" should be so trivial compared to all the processes I am running. I have windows open and am giving it 80% of my memory. But on the mac side I have chrome with 10 tabs, word, powerpoint, and many instances of excel open. Nothing is running slow or having issues. Except my sound has a crackle. The argument that there is not enough memory to do that seems fundamentally flawed upon any logical inspection. Unfortunately, I need windows to get 80% of the memory. So what is the real fix here Parallels.

 

Yes I've also been mulling over that. How could old computers with kilobytes and megabytes as memory play sound fine without any crackling noise, but a new computer with 32 GIGAbytes RAM can't do it? I am able to run very heavy programs and processes in my Mac view, I can have basically unlimited tabs open in Chrome without any slowing down (my old computer from 2017 completely died of all my tabs ) etc. but I can't play audio in Parallels because of ... low memory? I just can't understand how audio could demand so extreme amount of resources ...

 

I may have found a working solution. I use a Macbook pro 16 with m1 pro and have the standard version of parallels.
In the settings you will find the option adaptive hypervisor under CPU/RAM. This function has to be switched off and then the sound problem was solved for me.
maybe it will work for you too!

Best wishes

Excellent find. Trying this setting disabled as well.

 

Tried disabling hypervisor to no avail. The only thing that's worked for me in some sense is to renice Parallels and the processes within the VM using audio to -20. Then the audio is working for a few hours before the crackling starts again ... So there seems to be some kind of build-up of something over time that is slowing down the audio to make it start crackling. The only thing then is to completely restart the Mac. I wish there were some cache or something I could just reset when that happens instead of restarting the computer, but oh well, at least I get good audio for a few hours at a time

 

Same problem here, MacBook Pro M1 32GB, lots of crackling audio. Using `nice ` helps a bit, it crackles less frequently, but it still crackles. I'd hoped to use audio software in Windows but the crackling is a problem. Parallels support said it was a Windows problem and to contact Microsoft, I don't see how that could be true though. I tried things like reducing bit depth and frequency of the audio driver in Windows but that didn't help. Also tried the above suggestion of altering advanced settings as well as number of cpu cores but it didn't help. It'd be great if Parallels were to acknowledge this problem

 

Yeah I have a hard time believing it would be a Windows problem, since I've never experienced this on any Windows computer except for one. It was an old laptop and the audio would start stuttering when I had too many tabs open in Chrome or just used up too many resources in other ways. But I have another old (10+ years) PC I use for gaming and watching movies and TV and there have never been any problems with the audio there whatsoever. I can't believe a top of the line Macbook Pro M1 32 GB is too weak to play audio in Windows.

 

This problem remains unresolved. It is not limited to M1 but present on all Apple Silicons. And VMWare does not have this issue, so it is a bug in Parallels Desktop.

 

Try changing the sound settings in Parallels, it might help. Disabling Adaptive Hypervisor worked for me.

Thanks for the suggestions. Sadly, none of them helped. Tested on MacBook M1 Pro 16 GB Ram and Mac Mini M2 Pro 16 GB with the professional version of Parallels Desktop running Windows 11 Pro. Allocating 8 or 10 GB memory to the VM doesn't change anything. Neither does reniceing the process or disabling the hypervisor. (There is no choice between Paralells and Appels Hypervisor anymore.) Disabling isolation reduced some of the crackeling, but not much.

 

You might need to adjust configurations after the upgrade. Watch out for potential errors.

 

What you mean? What configuration needs to be updated? And since VMWare Fusion does not have any issues on the same machines, I doubt we talk about a user issue. Right now I am highly disappointed by the quality of the software and its price tag.

 

Same issue here on Mac Studio with Parallels 19 running Windows 11 and foorbar2000. The sound issue occurs after few hours playing music. VMware Fusion does not support coherence mode when running Windows Arm architecture. That's why I switched to Parallels but now I am really disappointed that the sound that Parallels cannot fix this issue.
