From cdc693643271b2e6a693cf8f6afb258cce01f058 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Wed, 10 Dec 2008 13:55:49 +0000 Subject: ALSA: Add support for mechanical jack insertion Some systems support both mechanical and electrical jack detection, allowing them to report that a jack is physically present but does not have any functioning connections. Add a new jack type for these, allowing user space to report faulty connections. Thanks to Guillem Jover for the suggestion.
