Sharp power-down snap is there with '27/20/14 ms' and '55/40/27 ms' but not times above. Beep sound is here when ramp is '109/81/55 ms' and above. As ramp time increases, the beep sound frequency goes down. Codec HW issue? I don't have any objections to these two patches and as the music still plays fine so probably these can be pushed in safely. -- Jarkko _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
