138 * Soundcard manufacturers have connected actual inputs (CD, synth, line,
139 * etc) to these inputs in different order. Therefore it's difficult
140 * to assign mixer channels to to these inputs correctly. The following
141 * contains two alternative mappings. The first one is for GUS MAX and
142 * the second is just a generic one (line1, line2 and line3).
143 * (Actually this is not a mapping but rather some kind of interleaving
144 * solution).

152 * Table of mixer registers. There is a default table for the
153 * AD1848/CS423x clones, and one for the OPTI931. As more WSS
154 * clones come out, there ought to be more tables.
155 *
156 * Fields in the table are : polarity, register, offset, bits
157 *
158 * The channel numbering used by individual soundcards is not fixed.
159 * Some cards have assigned different meanings for the AUX1, AUX2
160 * and LINE inputs. Some have different features...
161 *
162 * Following there is a macro ...MIXER_DEVICES which is a bitmap
163 * of all non-zero fields in the table.
164 * MODE1_MIXER_DEVICES is the basic mixer of the 1848 in mode 1
165 * registers I0..I15)
