 * Inverted digital-mic handling
 *
 * First off, it's a bit tricky.  The "Inverted Internal Mic Capture Switch"
 * gives the additional mute only to the right channel of the digital mic
 * capture stream.  This is a workaround for avoiding the almost silence
 * by summing the stereo stream from some (known to be ForteMedia)
 * digital mic unit.
 *
 * The logic is to call alc_inv_dmic_sync() after each action (possibly)
 * modifying ADC amp.  When the mute flag is set, it mutes the R-channel
 * without caching so that the cache can still keep the original value.
 * The cached value is then restored when the flag is set off or any other
 * than d-mic is used as the current input source.
