I’ve only recently realised that a lot of my ASIO drivers don’t appear to bypass the Windows volume mixer and therefore don’t appear to be true ASIO drivers at all. I’m puzzled by this and can’t seem to find an answer to the question by Googling it. Are a lot of ASIO drivers out there actually fakes – just plain old WDM drivers clad in an ASIO wrapper to make them look as if they’re functioning in ASIO mode, like ASIO4ALL? Here’s what I’m talking about. Let’s say you’re listening to music from your PC through an external USB soundcard. You’ve downloaded the ASIO driver for this soundcard and carefully selected the ASIO driver as the ASIO playback device in your media player or DAW (in my case, JRiver or Adobe Audition). You start ASIO playback and then, out of curiosity, you click on the volume icon in the bottom right-hand corner of your Windows PC screen. This opens the Windows volume mixer. By definition, your ASIO playback device shouldn’t be visible there because the whole point of ASIO is that it bypasses the Windows audio stack. But there it is – and what’s more, by altering the volume slider, you can change the playback volume! Now, that can’t be right. I’ve tested the ASIO devices that I have readily to hand on my Windows 10 PC and so far, I’ve found three “fakes” and two true ASIO drivers, as follows: 1. NAD M32 all-digital integrated amplifier with USB connection to PC. Fake! The ASIO driver goes through the Windows volume mixer and the volume can be changed from there. 2. Lynx Hilo D/A and A/D Converter. True ASIO! The ASIO driver NEVER appears in the Windows volume mixer at any time. 3. Yulong U200 headphone DAC/amp. Fake! The ASIO driver is there in the Windows volume mixer and you can change the volume using the slider. 4. iFi Nano DSD headphone DAC/amp. True ASIO! The ASIO driver never appears in the Windows volume mixer. 5. NwAvGuy ODAC + O2 headphone DAC/amp. Fake! The ASIO driver (supplied by Savitech Corp.) is always there in the Windows volume mixer. Incidentally, in all cases where the ASIO driver goes through the volume mixer, the Wasapi driver does too, which is also incorrect. I’ve written to Steinberg asking if there are a lot of fake ASIO drivers out there but in the meantime, I wondered if anyone here could explain it? Also, I’d be interested to hear if other people can see their ASIO drivers in the Windows volume mixer and change the playback volume using the mixer controls.
