This property value is populated by an audio OEM in an .inf file to indicate that the HDAudio hardware supports event driven mode as per the WHQL requirement.
Maybe you read into that that events are required. My read is that it requires the driver to indicate if it supports events -- or not. The xonar dx driver does not indicate either - it's empty.
I can see some hardware not doing events. For example, if you go way back to the Multisound (the original), or very first Soundblaster (waveform did not work in Win31). Those did programmed I/O instead of using a buffer filled by DMA. Using DMA you get hardware events as often as you like when the dma location reaches what positions you are interested in (typically at the middle and end). Using programmed I/O you don't. But programmed I/O in this day (well, since Windows 3.1) is too unlikely, but maybe the driver people didn't want to bother. One could probably assume that events are going to happen and not do the API call to check. Me, I'd rather check.
I wrote those two options before I checked it out in my code (lengthy process since another machine). What fb2k does is not check if event mode is supported. In other words, damn the torpedos, full speed ahead is fb2k's way. Probably like playing golf while thunder is about. Not gonna happen to me... haha

Hi there! @WilB, thanks for your cool script! I noticed some differences in design between the JSP and SMP versions: 1. font color (see cursor.jpg) 2. align the highlighted text vertically (see word "Affection" at cursor.jpg) 3. horizontal line color (see line.jpg) please check it, is this how it should be? or need to lead to uniformity.
I would like to point out that Biography 1.0.0 does not work properly: When foobar is started and the first song is played, no artist picture appears. The Foobar stub image is displayed, although some Artist images are already stored in the cache. Only when the second song is played the artist images appear. From now on Biography-Script works correctly. I would be happy if this bug is fixed. Here runs Foobar 1.4.1 with the current Spider Monkey. With Biography 0.9.0.2 this bug did not exist. Sorry for my English.
