 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. By default, the games look for a specific sound card in the registry, [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 `-sdvxasio`) to override this to use your own ASIO device.
+So far, only IIDX and SDVX have native support for ASIO. By default, the games look for a specific sound card in the registry, [Asus Xonar AE](https://github.com/spice2x/spice2x.github.io/wiki/Asus-Xonar-AE), which is what the arcade cabs use.

+Alternatively, you can try to convince the game to use your ASIO-compatible device:
+
+1. Open `regedit`
+1. Browse to `HKEY_LOCAL_MACHINE\SOFTWARE\ASIO` and expand.
+1. Take a note of the exact string under `ASIO` - e.g., `Realtek ASIO`
+1. Type it into `-iidxasio` or `-sdvxasio` option in spicecfg.
 
 > [!WARNING]  
 > Software ASIO drivers, such as ASIO4ALL, ASIO4ALL v2, FlexASIO are **not** going to provide you with better latency in most cases. They are receiving ASIO and then converting them to WASAPI Exclusive or Shared in the back end (on your CPU). If your hardware does not natively support ASIO, avoid these software solutions, and instead try to change spice options and/or patch the game to use **WASAPI Exclusive** for best performance. These are only really needed in case where the game is incompatible with your audio device; e.g., for games that cannot be patched to output to your desired audio mode.
