Audio cannot be directly captured by another application, so a workaround is needed to record or share the audio stream.
So far, only IIDX and SDVX support ASIO. The games look for a specific sound card, [Asus Xonar AE](https://github.com/spice2x/spice2x.github.io/wiki/Asus-Xonar-AE). If you purchase this card and install it, it will just work. Alternatively, you can use options in Spice (`-iidxasio` and `-sp2x-sdvxasio`) to override this to use your own ASIO device.
> [!WARNING]
> Software ASIO drivers, such as ASIO4ALL, ASIO4ALL v2, FlexASIO are **not** going to provide you with better latency in 99% of cases. Since these drivers rely on your CPU to manager buffers, you may actually end up with worse overall performance (lower framerate, audio glitches, etc). If your hardware does not natively support ASIO, stick to WASAPI Exclusive.

If your hardware does not natively support ASIO, stick to **WASAPI Exclusive** for best performance.
There are also software ASIO endpoints (e.g., FlexASIO) that will receive ASIO streams and convert them to other modes, such as exclusive or shared WASAPI. Keep in mind that this is just a software conversion, so you pay latency cost, which is not desirable.
