alsa-project/alsa-lib issue #199 was opened from gkubaryk: after upgrading the following packages, there is no audio: =media-plugins/alsa-plugins-1.2.6 =media-sound/alsa-utils-1.2.6 =media-libs/alsa-ucm-conf-1.2.6 =media-libs/alsa-lib-1.2.6 I checked each of the four individually and the last one (alsa-lib, 1.2.5.1) is the one that restored audio. alsa-info.sh output, as run from 1.2.5.1 (but it downloaded the newer version of the script to /tmp) is at http://alsa-project.org/db/?f=f94a60ff547f9cce9e872acae67fdf35473fa754 let me know if I can be of further assistance; I need the audio working for the rest of the day but would be able to provide output from 1.2.6 tomorrow perhaps, if desired.
