Hi all,

I've upgrade my computer and after reboot I got alsasound script fail.

I've updated media-libs/alsa-lib and media-sound/alsa-utils to 1.0.27

I've try to remove asound.state from /var/lib/alsa and re-save oundcard status ( with /etc/init.d/alsasound save )

I 'got this error

MyComputer ~ # /etc/init.d/alsasound save

Fixed in =media-sound/alsa-utils-1.0.27-r1 a hour after 1.0.27 was committed... since this looks like


# emerge --sync
# emerge -1 ">=media-sound/alsa-utils-1.0.27-r1"
