    ALSA: hda - Make converter setups sticky · eb541337
    Takashi Iwai authored
    So far, we reset the converter setups like the stream-tag, the
    channel-id and format-id in prepare callbacks, and clear them in
    cleanup callbacks.  This often causes a silence of the digital
    receiver for a couple of seconds.
    
    This patch tries to delay the converter setup changes as much as
    possible.  The converter setups are cached and aren't reset as long
    as the same values are used.  At suspend/resume, they are cleared
    to be recovered properly, too.
