• 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!

The A4A Info device enumeration utility has been updated somewhat. Usage is as always:

Download “a4ainfo.exe”


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

  • Allow Pull Mode (WaveRT)

    Allow Pull Mode (WaveRT)

    Note: These controls have no effect for WaveRT packet devices. Packet devices do not support polling – and always will use event mode. Therefore, the entire “Options” section may be hidden for packet devices. This is not a bug! There are two basic access methods for a WaveRT device, “pull-mode” (also called “event-mode”) and “push-mode”… more

  • Always Resample 44.1<->48 kHz

    Always Resample 44.1<->48 kHz

    ASIO4ALL can do real time resampling of 44.1 kHz audio to/from 48 kHz. Resampling will automatically take place whenever ASIO4ALL is opened for 44.1 kHz and the WDM driver does not support this sample rate. There may, however, be instances in which case an audio device will support 44.1 kHz only by resampling internally. More… more

  • Force WDM driver to 16 Bit

    Force WDM driver to 16 Bit

    This option only has an effect if the supported bit depth of the WDM driver is larger than 16, but less than 24. Some devices report e.g. 20 Bits resolution but cannot actually be opened for more than 16 Bits resolution. Should this be the case on your system, this option provides a workaround.
