came across a tweak which I think makes a quite an amazing difference, can hear much further into the music.

tried it on win 10 and it involves giving the windows audio service it's own process instead of sharing it.

You get the service name from the services tab in task manager under Name, on mine it is Audiosrv

open a cmd window in admin

type the command below (note space after = sign)

sc config Audiosrv type= own

press return and reboot, when you look at Audiosrv in the services tab of task manager you'll see it's got it's own pid.

There might be other services that share a pid, but that seems to be the main one for audio.

to reverse it type (though don't know why you'd want to)

sc config Audiosrv type= share

and reboot

No doubt windows x will be along to borrow it for fidelizer, try it now while it's still free.

another shared svchost service that makes a difference is AudioEndpointBuilder

sc config AudioEndpointBuilder type= own

Nice to come across these nuggets

Hi Gordon,

you can produce an overview on all mapped to svchost.exe services with the tasklist.exe utility.

tasklist /SVC /FI "IMAGENAME eq svchost.exe"

More details can be found here:

Take care

thanks Thomas,

splitting services out of svchost shouldn't be done without realising that you may not be able to reboot the machine if you get it wrong because some processes expect to be in the same memory space.

Having said that it seems to work for Audiosrv and AudioEndpointBuilder.

Checked the SQ again today to confirm that it makes quite a nice improvement.

Gordon will that effects WASAPI only?
I don't think it will KS or ASIO
In Core mode I don't see any audio services running either
Thank you

asio does it's own thing, so should improve ks and wasapi.

don't have win server so can't help there.

this link says it has Audiosrv

Hi elaprince,

using AO in core mode switches both services off, they are not needed because of Phil's way to enable KS in core. With Asio you would not need them either in different environment like Server 2016 or win10.

But you can get an inside with the described methode what is going on in your system under the svchost service and might tweak again ;)

As Gordon mentioned, be sure to have a backup if the system fails to boot ;)

Happy tweaking
Thomas
