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. / Hans --- Hans Wilmers Notam Sandakerveien 24 D, bygg F3 N-0473 Oslo Norway tlf.: +47 22358060 mob.: +47 92459361 <a href="http://www.notam02.no" rel="noreferrer" target="_blank">http://www.notam02.no</a> On 16/08/2019 07:09, Banibrata Dutta wrote: > 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 ? > > On Sat, Aug 10, 2019 at 8:22 PM Hans Wilmers <<a href="mailto:hanswil@notam02.no" target="_blank">hanswil@notam02.no</a> > <mailto:<a href="mailto:hanswil@notam02.no" target="_blank">hanswil@notam02.no</a>>> wrote: > > Hi, > there are several possibilities to make the guest OS access USB > peripherals (almost) directly: > > USB Redirect > and > USB Passthrough > > <a href="https://github.com/kimduho/kvm/wiki/KVM-USB-Redirect-or-Passthrough" rel="noreferrer" target="_blank">https://github.com/kimduho/kvm/wiki/KVM-USB-Redirect-or-Passthrough</a> > > 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. > > / Hans > > > --- > Hans Wilmers > Notam > Sandakerveien 24 D, bygg F3 > N-0473 Oslo Norway > tlf.: +47 22358060 > mob.: +47 92459361 > <a href="http://www.notam02.no" rel="noreferrer" target="_blank">http://www.notam02.no</a> > > On 10/08/2019 10:34, bdutta wrote: > > 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.
