No sound at Catalina 10.15.2! (Parallels Desktop 15.1.2 for Mac)

Dear Parallels team,
Please help me with my issue. I can't solve it without you.
-----
My today config:
Host system is: MacOS Catalina 10.15.3
Parallels Desktop for Mac Pro Edition: version 15.1.2 (47123)
-----
I was at macOS Mojave (version 10.14) and PD 15.1.2 - all worked good.
The problem started when i have updated to Catalina 10.15.2.
Now when i run more than one virturtual machines at the same time, system sound is not working!
When i stop one of the running ones - sound returns back.
If not returns, i kill the process coreaudiod in my host Catalina. It becomes killed, than MacOs restarts it automatically and sound returnes.
The method with killing coreaudiod works if only one machine is still working. If two or more vm works, sound isn't returned even after killing of the coreaudiod process.

I use your last Parallels Desktop for Mac distributive with 5 virtual machines with Ubuntu 18.04 and another MacOS Catalina 10.15.2.
It is not matter what virtual os to start - sound disables when any two of them became "running" status.
I tried to undestand the moment of sound disabling. When i click at button run and PD is restoring os from pause - sound is still working. But when a loading circle hides, system sound turns off.

I don't know what to do because my working process became too hard: i don't hear sound of notifs and alerts from messangers in one virtual os when i work in another one.

Today i have updated to Catalina 15.1.3 and nothing is happend. The problem is still remains.
Please help me to solve the problem!
Regards.

I am on BigSur 11.2.3 + Parallels 16.1.3 and the problem is here big time.
Only solution is (for me) to suspend the VM, then wake it up.

Hi, I found a fix for my setup (macOS 10.15.7, Parallels Desktop 16.5.0 for Mac, VM: Win10, 20H2, 19042.928):
  • giving the Parallels desktop App full disk access under macOS security settings (not sure if that is really needed)
  • in the advanced Sound & Camera settings of the VM I chose "AC'97" and then the "Parallels Audio Controller" did show up under the windows devices
Hope this is useful for you -- oh and I use a thunderbolt 3 hardware audio device with the VM.

Where can I "the "Parallels Audio Controller" did show up under the windows devices".... in Parallels?

I have the same problem with Mac audio and video with Ubuntu VM (latest Big Sur 1.4). I had this issue for a long time already. It is really annoying. Audio and video stop working after a while when I open a VM. I work constantly in my ubuntu VM thus anytime I have a meeting I need to close my VM and do a
sudo killall coreaudiod. I hope parallels fixes this issue soon. I have been considering moving to other VM tool.

I completely removed the sound hardware from the VM and it still did it. I found a workaround though: lower the RAM and CPU to 4GB and 2 cores respectively.

somehow this stopped it from stealing my audio and it made Mac faster AND the windows VM faster. Seems like there is a bug when assigning more than 4GB of RAM.

After updating to Catalina 10.15.2, Airpods stopped working with my Macbook. Apple mentioned these steps and I tried but not working. I followed this article https://geniusgeeks.com/airpods-sound-microphone-muffled/ and also followed Apple guide which is this "Make sure the speakers are connected to the audio out port on your Mac or display, as well as a power supply if necessary. On your external speakers, look for a power switch and a volume control. Turn on the speakers and adjust the volume if necessary."

Still facing the issue.

So I also have a similar problem with sound. Whenever I run Parallels it kills my system sound. Can't make Teams calls from my Mac, my mic and speakers don't work. I plug in headphones but still no joy. It also kills YouTube. The videos stop playing sound and then, eventually, they stop loading altogether. If I shut down parallels all the problems go away.

Please fix this issue! It's making my day almost impossible!

MacBook Pro (16 inch, 2019) running macOS Big Sur v11.4 and Parallels Desktop 16 for Mac Pro Edition v16.5.1 running a windows 10 VM.

I just encounter the same exact issue with version 17 on Big Sur 11.5.1 on a MacBook Pro 15 in - 2017. The only workaround was to suspend the vm and reactivate. I resolved the issue by reverting to the last version of 16 and it hasn't occurred again.

I'm using 17 with 11.5.2 on a 15" 2017 Macbook Pro and have had this issue for some time but it *appears* that sound/mic works when I am not in coherence mode.

I'm using also 17 with 11.5.2 on a 15" 2018 Macbook Pro. I tried a lot and couldn't find the "trigger" inside my VM Windows 10 64bit. Today, when I changed to Hypervisor "Apple", my sound works the whole workday, so this seems to be the workaround. My Support ticket three days ago is still waiting to be answered.
Thanks to parallels for "quick" help :/

I was encouraged by the last release note "Resolves an issue with sound sometimes disappearing on a Mac after running a virtual machine" in the 17.1.0.51516 patch but this still does not resolve the issue.

same - Big Sur 11.6 / Windows 10 vm
The patch seemed to work for a few days and then it was back to 'normal' - so maddening to be on a call w/ work and then *poo* no audio.

Hi all,

I tried the latest macOS(12.3.1) with the latest parallels desktop(Version 17.1.2 (51548)).
Once I switched to Parallels hypervisor(from Apple hypervisor) I got the same sound issue. I think Apple hypervisor works fine, but a little slow(my feeling when compiling dotnet projects)

hi all,

After looking for all different solutions for the no voice device in win10 (including apple hypervisor, reinstall parallels tools...), I found there is no Sound & Camera in VM HW config settings in parallels app.

Just press the "+" to rejoin the Sound & Camera in HW setting and reboot VM, and sound setting in VM is back...
