From 2d4b842014dc76a81abced47ef27177eedb9deba Mon Sep 17 00:00:00 2001 From: Clemens Ladisch Date: Mon, 13 Jul 2009 13:52:46 +0200 Subject: sound: rawmidi: disable active-sensing-on-close by default Sending an Active Sensing message when closing a port can interfere with the following data if the port is reopened and a note-on is sent before the device's timeout has elapsed. Therefore, it is better to disable this setting by default.
