Your controller and codec certainly have dmix, dsnoop, and softvol enabled by default. However, nothing prevents a rogue application from grabbing plughw or hw or using OSS emulation (you have the kernel modules loaded). In other words, inspect the ALSA configurations of the audio applications that you use. If any of them are not using "default" as the device, there's a good chance you've located a culprit.
