XMMS (audio application, aviable in pkgsrc) consumes too much CPU (>60%)while playing a song with the eap driver. After analyzing a while, thinking the scope of the problem lied on the application I notice it was on the eap driver. I have two soundcards, one integrated on the motherboard I never use and never compile support for in the kernel. But after a try and compile a kernel without support for my second sound card, the one I always use (sb 128, es1373) with the eap driver, and compile a kernel with the integrated sound card I experienced that the problem was with the eap driver.

Notice this happens only with xmms with the eap driver. Other sound applications work well.
I have asked someone with this driver, xmms and running -current but he seems not to experience the problem. So I don't know exactly how to reproduce the problem for anyone.
don't know.
