Disclaimer: this bug has been filed in a semi-automated manner. When emerging the package media-libs/alsa-lib-1.0.25-r1, the following elog messages are displayed: * Please try in-kernel ALSA drivers instead of the alsa-driver ebuild. * If alsa-driver works for you where a *recent* kernel does not, we want * to know about this. Our e-mail address is alsa-bugs@gentoo.org * However, if you notice no sound output or instability, please try to * upgrade your kernel to a newer version first. Such messages should only be displayed when the package is a new install. These situations can be checked in the ebuild as follows: if ! has_version 'media-libs/alsa-lib'; then See the tracker bug 440214 for more details.
current alsa-lib ebuilds don't have postinstall messages
