The SysAudio driver represents audio filter graphs as virtual audio devices and registers each virtual audio device as an instance of a KSCATEGORY_AUDIO_DEVICE device interface. The SysAudio system driver (Sysaudio.sys) builds the filter graphs that render and capture audio content. The kernel-mode WDMAud driver is a kernel streaming (KS) filter and a client of the SysAudio system driver. WDMAud performs I/O for the following APIs: waveIn, waveOut, midiIn, midiOut, mixer, and aux (described in the Microsoft Windows SDK documentation). The pair of WDMAud drivers translate between user-mode Microsoft Windows multimedia system calls and kernel-streaming I/O requests. The kernel-mode WDMAud system driver (Wdmaud.sys) is paired with the user-mode WDMAud system driver (Wdmaud.drv).

Port Class Adapter Driver and PortCls System Driver What do I do wrong, or, in case this setup is not supported for some reason, what alternatives do exist? Every hint is welcome.The kernel-mode Microsoft Windows Driver Model (WDM) audio components are: If possible I would like to stick with it.

It was easy to install and did not need any configuration. VB-CABLE is using PortAudio V19.5.0 and supports several interface types (MME, Windows WASAPI and Windows Direct Sound). The voice example works fine with input: 1 or input: 2 as well as without the input parameter at all.įinally, to make sure I’m not completely wrong, I used the “CABLE Output (VB-Audio Virtual Cable)” for 2 Channel Stereo input for recording the output of HELM in Audacity. I also tried without the input: parameter at all. On input: I tried any number from 3 to 9. I tried as follows: # live_audio :voice, input: 1 I downloaded and installed this software, but now I dont know how get live_audio input from it. Googling around for an audio loopback device I found a software called VB-CABLE, which is a virtual audio device working as virtual audio cable.

However, I’m using Windows 10 and cannot get this to work. There is a tutorial on Youtube demonstrating how this can be done on a Mac. What I want to achieve is to send MIDI data to HELM and feed the output of HELM back to live_audio for input in Sonic-Pi. I’m currently trying to combine Sonic-Pi with HELM.
