ASIO4ALL – low latency ASIO driver for Windows audio
Site News
16 February 2022: Finally – Version 2.15 (final!)
- This version officially supports Windows 10 and Windows 11.
- Also confirmed to work with Windows 7 and Windows 8, with some minor GUI visual artefacts, though.
- Report bugs to feedback@asio4all.com!
Changes since version 2.15 (Beta 3):
- Workaround for Oculus VAD.
- Fix crash with Blackmagic Design DeckLink driver.
- Avoid using “Stereo Mix” input in default configuration.
- Fix erratic behaviour of “Force 16 bit” – option, especially when WDM driver does not support a 16 bit sample data format.
28 January 2022: Debug build with trace output
| ASIO4ALL 2.15 with trace output | The debug build completely replaces the “a4ainfo.exe” debug utility and its usage procedure. Please do not complain that the “a4ainfo.exe” download link from further down this page redirects you up here, now!
Install and run normally, until the error happens, which you would like to report. Then exit your audio application. The debug build will have created a trace log file on your Windows desktop (in plain text format). This can be used to submit problem reports per email – along with a meaningful error description, of course -> feedback@asio4all.com!
Again, you will likely get a SmartScreen warning at least during the following few days. |  |
19 January 2022: Some corrections to version 2.15 (Beta 3)
- Fix encoding and spelling errors in the Chinese and Turkish localization
- Installers are now digitally signed. Ironically, this may trigger a SmartScreen warning – while distributing totally unsigned executables – year after year in the past – did not. Go Microsoft!
- As there were no functional changes, the Beta 3 download links have just been updated, without a version number change.
20 December 2021: Version 2.15 (Beta 3)
- This version officially supports Windows 10 and Windows 11. Older versions of the OS may (and likely will) still work, but we no longer claim to be supporting them.
- Released in all languages currently supported, in order to also spot localization errors.
- Report bugs to feedback@asio4all.com!
Changes since version 2.15 (Beta 2):
- Resolve potential Windows 11 compatibilty issues.
- Fixes and workarounds for on-board audio on newer AMD systems (like Ryzen 5000).
- Fix a number of issues related to WaveRT packet support.
- Fix GUI visual distortion on high DPI display.
- Improve backwards compatibility with Windows 8 (no official support, though!)
21 April 2021: Version 2.15 (Beta 2)
- This version supports Windows 10 only. Older versions of the OS may (and likely will) still work, but we no longer claim to be supporting them.
Changes since version 2.15 (Beta 1):
- Fix: Sometimes, sample data was truncated to 16 bits on high resolution devices.
- Fix: “Internal Heap Overflow” – message with 32 bit applications on some systems. 64 bit programs were not affected.
- Fix: Sometimes a cryptic string was appearing as USB device channel name inside host ASIO settings.
- Changed AsioGetChannelInfo() to group channels by individual device.
- GUI now showing the audio data format currently used, instead of the capabilities, for any active item.
- Further GUI cleanup
11 March 2021: Version 2.15 (Beta 1).
- Major update, therefore in beta first!
- This version supports Windows 10 only. Older versions of the OS may (and likely will) still work, but we no longer claim to be supporting them.
Changes since version 2.14:
- Workaround for bug in Windows 10 Creators Update reverted, as Microsoft meanwhile have fixed the original issue.
- ASIO4ALL now aware of Intel(R) SST and working around several issues
- Refactoring WaveRT implementation for both, pull mode and polling. Fix an issue that in 64 bit mode ASIO4ALL would not use the position register, but rather the legacy mechanism
- Improve support for WaveRT packet devices. USB audio class 2.0 devices should work much better now
- Some audio devices were not detected by ASIO4ALL
- Full Unicode support for visuals
- GUI now also works with higher screen resolutions
- Further GUI cleanup
- Instruction manual now online, accessible through a GUI help button
- Completely dropped support for “ReWuschel” and Off-line settings. You could still re-enable “ReWuschel” by setting a registry key, but who really still uses software that is more than 20 years old?
11 February 2021:
The A4A Info device enumeration utility has been updated somewhat. Usage is as always:
- Download the .exe
- Open a command prompt and run “a4ainfo.exe” (ideally from where you downloaded it or some other directory location actually containing the .exe)
- A plain text file “a4ainfo.dbg” will be generated – send this to feedback@asio4all.com – along with a detailed error description!
Important!
This is not a new version of the ASIO4ALL driver! This does not install anything. The only thing it does ist create a plain text file containing information about your audio devices. There also is very little utility in sending me just the file without some sort of a useful error description!
E.g. What exactly does not work, what do you see in the ASIO4ALL GUI, etc…
07 February 2021: Developer resources added.
05 February 2021: Moved site to WordPress.
It should be possible now to add content more quickly – as opposed to the previous approach: Using plain HTML inside a text editor [sic]. So it may happen that the transition broke one or the other thing on the site. In which case you either let me know – or I’ll eventually figure myself. Needless to say that there also is a new software release in the pipe!
23 May 2017: Version 2.14 released!
- Combined 32/64 bit version, supports Win 98SE/ME/2k/XP/MCE/2003/XP64 and Vista/Windows 7/Windows 8.x/Windows 10 x86/x64
- There is just one single change in this version. If your system is not affected, there is no reason to upgrade. Localized versions will not be provided, for the very same reason.
Changes since version 2.13:
- Workaround for a bug in Windows 10 Creators Update: USB audio capture would not work any more (red exclamation mark, distorted sound, …)
05 November 2015: Version 2.13 released!
- Combined 32/64 bit version, supports Win 98SE/ME/2k/XP/MCE/2003/XP64 and Vista/Windows 7/Windows 8.x/Windows 10 x86/x64
- Minor update. Now Windows 10 is officially supported, even though it has been working all along.
Changes since version 2.12:
- Workaround for a bug in the Windows 8/8.1 Bluetooth audio driver (causing BSOD when device is opened twice). This bug seems to have been fixed in Windows 10.
- Improvement: UI response time and driver (re-) start time should be a lot snappier now.
- Fix: Some Application Verifier errors should be gone.
