![]() ![]() ![]() I haven't looked at present-day Linux for that but that's pretty much a lot to ask from a general-purpose O/S. The thing is that general software doctrine and "get every last cycle outta the thing" doctrine intersect only now and again and only uncomfortably.Įdit: For all that, the guarantee that must be met for an interface to be serviced 96000 over USB with a sample depth of 16 is 1/6th of a millisecond - no exceptions. It's all actually quite a fascinating subject but there's a lot of boring stuff in there. Chord Hugo TT2 ASIO exclusivity getting hijacked by Win11 Support MattG January 12, 2022, 9:08am 1 Roon Core Machine Roon Core on Win10 machine Roon 1. I'm using "latency under 1msec" as a very broad definition of "realtime". Now - all that being said, I can ( and have ) gotten realtime performance outta Linux kernels but it wasn't easy. The horror :) that was Windows Multimedia at least allowed getting the performance, latency and jitter needed for the old chips. Which is surprising but not all that surprising. I was on a project then and we tried to make RT Linux work and it just wouldn't. It wasn't bad but I guarantee you it was not the same. That meant "realtime priority threads" which was. 2004, 2006 WindRiver basically decided to put VxWorks on a "this is for charging the foo outta legacy defense contractors" basis and started touting "real time linux" which really meant "Linux with the realtime extensions". At the time of Linux' founding, RTOSes were RTOSes and Linux was Linux.Īround. I think architecturally Linux has an advantage over Windows when it comes to real-time audio processing. And stop believing ignorant claims online by people like OP who don't actually understand what they're talking about. Measure, test, see what works FOR YOUR PARTICULAR CASE. In fact for some PC configurations (it's certainly the case with mine) and some audio hardware (in my case a 2nd gen Scarlett 2i2) ASIO4All do that job better than vendor ASIO drivers. Just by working for a company creating audio hardware some group of programmers are super great at implementing ASIO drivers isn't really how it works, unfortunately. Your audio interface provided ASIO drivers actually themselves do a very, very similar thing - as no audio hardware is made with one particular API (be it ASIO, CoreAudio, ALSA or whatever) in mind. The WDM bits ASIO4All wraps expose those buffers. Under Vista, all the crap they put into their XP WaveCyclic miniport has been moved into the user mode audio engine and is completely bypassed by ASIO4ALL.You obviously have no clue what a virtual machine is, do you?ĪSIO4ALL is wrapping parts of a kernel WDM module, which in itself already has all it takes to be a low-latency driver (really not much worse than, say, CoreAudio on Mac is) except Windows themselves don't utilise them as such as low-latency audio is utterly unimportant to Microsoft.ĪSIO is Steinbergs API to interface low-latency audio buffers in audio hardware. ![]() Under Vista they cannot pull these tricks, because here the driver is a WaveRT miniport, where WaveRT is a zero copy approach. See the Realtek thread for that matter! Solution is to roll back the Realtek driver to a known "good" state and once this is done, it'll be "single client" as a side effect. Anyone know of any windoz Fixes for this issue?Ĭhances are you have a Realtek High Definition Audio onboard thingy and the reason why it appears to work in XP is that Realtek have integrated some dodgy software mixing into their miniport for Win XP - at the price of horrible latency and more issues. ![]() So for those that say running multiple apps with asio is not possible, I say it is but perhaps not with Vista. I can get 0ms latency with it and it sounds great. My sound card is just a plain jane Realtek HD Audio built in device. Really handy for learning songs on the guitar. Guitar Rig, and Guitar Pro 5 and Internet Explorer, all of which could play sound at the same time. When I was using XP I had multiple programs running at once. Since I "upgraded" to Vista from XP I'm having this problem as well. Here's a good discussion about this issue: You shouldn't have any problems with "regular" audio like YouTube + ASIO, though. Eg: Reaper running ASIO4ALL and Winamp running Behringer's ASIO should be fine. If you have several playback devices listed here, right-click and select Disable on any device that isnt currently set as the Default device. Right-click the speaker icon in the Windows System Tray (bottom right) and select Playback devices. You can use two different ASIO drivers at the same time, but you can't use the same ASIO driver in more than one software simultaneously. Re: FL Crash when changing to ASIO4ALL v2. Just to be clear, I also can't use the same ASIO driver in more than one application and I think this is a limitation of the ASIO standard itself. ![]()
