We had run a latency check using LatencyMon Application on a VMware guest(Windows 7 x64 bit) in VMware workstation 15 Pro. But the test fails and says that "Your system appears to be having trouble handling real-time audio".
We have tired it with the following specification(Guest OS - VMware settings):
Memory: 6.2 GB
Processors: 1
Hard Disk(SCSI) : 60GB
We are using a system with specification:
Memory: 8.00 GB
Processor: Intel(R) Core(TM) i7-5600U CPU @ 2.60GHz 2.59GHz
Hard Disk: 256 GB SSD
We have attached the result screenshot with this post. We want to play and record simultaneously in audacity but the LatencyMon shows that vmware guest is not supporting real-time audio streaming with this specification.
We need to know whether there is a problem with VMware workstation for real-time audio recording or with our PC specification?
Do you use the VMware audio card or an external USB-soundcard directly connected to the VM ?In my experience using a DAW inside a VM only makes a little bit of sense if you use an external USB-audio device connected to the guest directly.
All attempts to get decent results with the VMware-audiocard failed for me.
What was almost usable was a test with a MacOS VM using Garageband via a Tascam USB-audio device.
But honestly even that was hardly bearable ....
So to sum it up: you are expecting too much IMHO.
By the way - try with significantly less RAM for the VM - start with 2 GB instead of the 6.2 GB that you have assigned now.
Hi,
This output does not surprise me considering that there's special kernels for Linux to handle real-time audio and video which are intended to be run on physical hardware.
Real-time demands and virtualisation are just not the best match.
If it ends up being a problem for you by trying to use this in a VM depends on your demands and your ability to tweak the VM configuration for minimum latency.
Hint: start out small.
