	Здравствуйте.
Это только у меня все 2.6.30 в округе (std-ng-2.6.30-alt1, 
std-def-2.6.30-alt1, lks-wks-2.6.30-alt0.4) не слишком редко
умудряются скипать звук на T41p (P4M 1.6, ICH4/ICH4-L/ICH4-M)?

Наблюдается при работе mplayer, xmms, psi (то есть aplay).
На 2.6.28 и предыдущих такого не припомню.

pad:~> rpm -qa | grep alsa | sort
alsa-oss-1.0.17-alt3
alsa-plugins-1.0.20-alt2
alsa-plugin-xaudio-0.6.1-alt1
alsa-utils-1.0.20-alt2
kernel-modules-alsa-lks-wks-2.6.28-alt2
kernel-modules-alsa-lks-wks-2.6.30-alt0.4
kernel-modules-alsa-std-def-1.0.16-alt4.132633.8
kernel-modules-alsa-std-def-2.6.27-alt8
kernel-modules-alsa-std-def-2.6.30-alt1
kernel-modules-alsa-wks-smp-2.6.26-alt5
libalsa-1.0.20-alt2
vlc-plugin-alsa-1.0.0-alt0.rc4
xmms-out-alsa-1.2.11-alt8

rc.local (в основном по энергосбережению, и давно не менялся)
прилагается.
