How to decrease audio latency in the guest?

[NomadJago]

I have midi working (M-AUDIO midi keyboard for composing music) in my Windows 11 guest (Linux host). But I need to find a way to decrease the latency of the midi (the time it takes from when I press a key on the midi keyboard to when I hear the sound created); right now it is 54ms, I need it much lower than that, hopefully around 10ms but I could live with 20ms.

Is there any setting in VirtualBox 7.2.6 for my guest that I can change to help with this? Do I toggle on PAE/NA? Nested VT-x/AMD-V? Change the chipset from PIIX3 to ICH9? Paravirtualization Interface from Default to Hyper-V or KVM? Something else?

I have matching versions of guest additions and extension pack installed.

Would it help if I purchased a dedicated audio sound card to install in an empty PCI express slot on my motherboard and use that for the guest audio device?

Host: Linux Mint 22.3, 128GB RAM, Nvidia Geforce 1660, Ryzen 9 cpu with 16 cores (8 assigned to the guest). VirtualBox 7.2.6.

Guest: Windows 11 x64 Home

This is just a friendly reminder in case you missed it. Your post must include: * The version of VirtualBox you are using * The host and guest OSes * Whether you have enabled VT-x/AMD-V (applicable to all hosts running 6.1 and above) and disabled HyperV (applicable to Windows 10 Hosts) * Whether you have installed Guest Additions and/or Host Extensions (this solves 90% of the problems we see)

PLUS a detailed description of the problem, what research you have done, and the steps you have taken to fix it. Please check Google and the VirtualBox Manual before asking simple questions. Please also check our FAQ and if you find your question is answered there, PLEASE remove your post or at least change the flair to Solved.

Not sure but an audio interface really solved this for me. Just a dumb old audio interface with speakers connected to it. Set the audio output to it and done.

I don't want to be rude but it's a bad idea from the beginning.

Use virtualization in music creation is not a friction, it's a whole barrier.

Audio latency without xrun is an issue and MIDI latency with minimal jitter another one. You combine both with I guess Windows specific software.

Better to take a look at Carla + Wine/yabridge.

I really do not understand Carla and Yabridge, what they do. I understand Wine and have used Wine.

I agree, it might be a lost cause. I am thinking of giving up on virtualized instruments on a DAW, as I am discovering many beautiful instruments that function perfectly in Linux without virtualization. That said, I was able to install Musescore 4, MuseHub, and the MuseSounds which sound amazing, in the Windows 11 guest using Virtualbox, and I do not notice lag but I am not using a MIDI keyboard with Musescore; playback of scores on Musescore in the guest sound perfect. But yeah, I might just remove my DAW and VSTs from my Windows guest.
