>Description:
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.
>How-To-Repeat:
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.

 FWIW, eap and xmms work fine for me without any "extra" cpu penalty.

 Which one is it consuming CPU, the driver or xmms? ie. is it using system
 or user time?

 Don't think this helps too much, sorry.

 time xmms -p "MACY_GRAY___SWEET_BABY__FEA.MP3"

 This happens only while using as audio output in xmms OSS driver 
 (libOSS.so), using eSound it does'nt consume anything almost. Strange 
 enough libOSS.so works fine with the auvia kernel driver.

 Tested both drivers (eap, auvia) with a GENERIC kernel.

There have been many changes to audio and liboss.
Is this still a problem with a kernel from -current and updated liboss?
