Hi Banibrata,
using USB redirect, the guest os is using its own driver, so I would
imagine guest kernel behaviour plays a role.
In my setting, "simple" listening works fine, but low latency causes
dropouts, which is not surprising as there is a busy network in between.
You may have better luck with the guest directly on the client machine.

Thank you for the reply Hans.So using USB redirect, I
can access any USB
audio interface, but shouldn't have to worry too much about the
interrupt latency or guest kernel behaviour, when it comes to
low-latency behaviour ?

Hi,
there are several possibilities to make the guest OS access USB
peripherals (almost) directly:
USB Redirect
and
USB Passthrough
https://github.com/kimduho/kvm/wiki/KVM-USB-Redirect-or-Passthrough
I can select USB redirect comfortably using a spice client, and a KVM
virtual machine on another machine - and it works fine even over the
network.

Hi,
Is anyone aware of any comparative study of various hypervisors (KVM,
VMware, Virtualbox) running Windows guests, on Linux hosts -- in
respect of
quality of audio software, in terms of latency,
jitter, glitches
etc. Based
on my reading, I've understood that accuracy
and reliability of
the timer
interrupt available to guest kernel (in VM)
should not be expected
to be
equal to same on bare-metal. However, are there
some hypervisors
(workstation oriented), that are better than others in this regard ?
The question is in context of need to run some Windows software which
doesn't work well under WINE (even with WineASIO, various
recommended
WINE
tricks applied), and I find the need to
setup/maintain a dual-boot
environment too cumbersome, as I do 90% of my work in Linux.
regards,
BD
