#undef AUDIOHW_SETTING /* will have been #defined in config.h as empty */
/* Use AUDIOHW_SETTING to create an audio setting. There are two ways to use this
 * macro:
 * AUDIOHW_SETTING(name, unit, nr_decimals, step, min, max, default)
 * AUDIOHW_SETTING(name, unit, nr_decimals, step, min, max, default, expr)
 *
 * It is important to understand that each setting has two scales: the hardware
 * scale and the user scale. In the first form of the macro, they coincide.
 * In the second form, the conversion from hardware to user is done by the
 * expression [expr] provided in the extra argument (see examples below). The
 * hardware scale ranges from [min] to [max], in steps of [step]. The default value
 * is [default]. Furthermore, when displaying the value to the user, [nr_decimals]
 * gives the number of decimal points to display. Thus if [nr_decimals] is 0 then
 * a value of x means x [unit]. If [nr_decimals] is 1 then a value of x means
 * x/10 [unit] and so on. Note that both [nr_decimals] and [unit] are irrelevant
 * to the hardware, they simply provide a flexible way to show natural value to
 * the user. When you want the user scale to be different than the hardware scale,
 * you must provide [expr], an expression that can use the variable "val", which
 * represents the hardware value, and converts it to the user value. The [expr]
 * can involved a function call in very complicated/nonlinear cases, as long as
 * the function does not have any side-effect. Finally, the [name] parameter
 * must be one of the settings listed in audiohw_setting.h
 *
 * Examples:
 *
 *   AUDIOHW_SETTING(VOLUME, "dB", 0, 1, -100,  12,  -25)
 * This describes the volume setting. The values are in dB (no decimal). The
 * minimum value is -100 and the maximum is 12, with a step of 1 and a default
 * value of -25. This means that the hardware can take any of the following value:
 *   -100, -99, -98, ..., 11,12
 * Since there is are decimals and no conversion expression, a hardware value of
 * x means x dB. So a value of -25 means -25 dB, a value of 5 means 5 dB.
 * WARNING VOLUME is actually special: whatever scale you choose, the sound code
 * will always set the volume by calling audiohw_set_volume() with a centibel
 * value (ie it will not perform any conversion). Thus it is strongly advised
 * that you always choose a VOLUME scale with precision 1 (centibels) and no
 * hardware conversion.
 *
 *   AUDIOHW_SETTING(MDB_CENTER,   "Hz",  0, 10,  20, 300,  60)
 * This describes the MDB (dynbamic bass) center. The values are in Hz (no
 * decimal). The minimum value is 20 and the maximum is 300, in steps of 10
 * and a default of 60. Thus hardware can take any of the following value:
 *   20, 30, 40, ... 290, 300
 * Since there are no decimals and no conversion expression, a hardware of x
 * means x Hz. So a value of 60 means 60 Hz.
 *
 *   AUDIOHW_SETTING(BASS, "dB", 1, 15,  -60,   90,    0)
 * This describes the bass control. Since there is one decimal, the values are
 * in tenth of dB. The minimum value is -60 and the maximum is 90, in steps of
 * 15 and a default value of 0. Thus hardware can take any of the following value:
 *   -60, -45, -30, ... 60, 75, 90
 * Since there is one decimal, a hardware value of x means x/10 Hz. So a value
 * of 60 means 60/10 = 6 dB. A value of -45 means -45/10 = -4.5 dB.
 *
 *   AUDIOHW_SETTING(DEPTH_3D, "%", 0,  1, 0,   15,    0, (100 * val + 8) / 15)
 * This describes 3D enhancement control. The values are in percentage (no
 * decimal). This setting makes a difference between hardware and user scale.
 * The minimal hardware value is 0 and the maximum is 15, in steps of 1 and
 * a default of 0. Thus hardware can take any of the following value:
 *   0, 1, 2, ... 14, 15
 * Because of the conversion expression, a hardware value of x means
 * (100 * val + 8) / 15) %. A hardware value of 0 means (100 * 0 + 8) / 15) = 0 %
 * because the result must be an integer (8 / 15 = 0). A hardware value of 1
 * means (100 * 1 + 8) / 15 = 7 %. A hardware value of 15 means
 * (100 * 15 + 8) / 15 = 100 %. In fact, from the user point of view, the range
 * of available values is:
 *   0%, 7%, 13%, 20%, ..., 93%, 100%
 *
 *   AUDIOHW_SETTING(LEFT_GAIN, "dB", 2, 15,-345, 1200, 0, val * 5)
 * This describes the left gain. Since there are two decimals, the values are in
 * hundredth of dB. This setting makes a difference between hardware and user scale.
 * The minimal hardware value is -345 and the maximum is 1200, in steps of 15 and
 * a default of 0. Thus hardware can take any of the following value:
 *   -345, -330, -315, ..., 1185, 1200
 * Because of the conversion expression, a hardware value of x means
 * val * 5 hundredth of dB or, in other words, (val * 5)/100 dB (where we keep two
 * decimals). A hardware value of -345 means -345 * 5 = -1725 hundredth of dB
 * = -17,25 dB. A value of -330 means -330*5 = -1650 hundredth of dB = -16,50 dB.
 * A value of 1200 means 1200 * 5 = 6000 hundredth of dB = 60 dB. In fact,
 * from the user point of view, the range of available values is:
 *   -17.25 dB, -16.60 dB, ..., 59.25 dB, 60dB.
 *
 *   AUDIOHW_SETTING(DEPTH_3D, "dB", 0, 1, 0, 3, 0, depth3d_phys2_val(val))
 * This describes 3D enhancement control. The values are in dB (no
 * decimal). This setting makes a difference between hardware and user scale.
 * The minimal hardware value is 0 and the maximum is 3, in steps of 1 and
 * a default of 0. Thus hardware can take any of the following value:
 *   0, 1, 2, 3
 * Because of the conversion expression, a hardware value of x means
 * depth3d_phys2_val(x) dB. If for example the conversion functions is:
 *   int depth3d_phys2_val(int val)
 *   {
 *     return val == 0 ? 0 : val * 5 + 30;
 *   }
 * then from the user point of view, the range of available values is:
 *   0 dB, 35 dB, 40 dB, 45 dB
