From bd869485993f73c303b565da5548bb4e77063c54 Mon Sep 17 00:00:00 2001 From: Jonathan Woithe Date: Tue, 28 Nov 2006 11:35:52 +0100 Subject: [PATCH] [ALSA] hda-codec - Make internal speaker work on Acer C20x tablets The following patch creates a new 'Mono speaker' control in alsamixer when the Realtek 'acer' model is used with hda_intel. This is needed so the internal mono speaker (when present) can be controlled. This new control won't do anything in Acer laptops which are not fitted with a mono speaker. Acer models which are known to have a mono speaker are the C20x tablet series but there may be others. I guess we could define a new model specifically for Acers with mono speakers but this seems a bit silly given that such a model will be identical to the normal 'acer' model except for this added control. This patch also adds the C20x tablets to the list of PCI ids associated with the 'acer' model. This means that owners of C20x machines will no longer have to supply 'model=acer' when loading hda_intel.
