I can also report that I'm having the same problem running kernel
2.4.[3-4{ac1-9}] with a C-Media using ESD. So the problem appears when I
tried to run XMMS with ESD, the sound have an annoying "ss ss ss
..." while I play mp3's. The frecuency of the "ss ss ss ..." is symetrical
(1/4 of a second I say).
The problem appears to have a direct asociation with esound cause it only
happens with the use of XMMS over ESD. No problems reported during
execution of mpg123 wich not use esound.
