    ALSA: oxfw: add support for Mackie Onyx 1640i · 03abd33a
    Takashi Sakamoto 提交于
    As of kernel 4.10,  ALSA OXFW driver has no entry for Onyx 1640i produced
    by Mackie (Loud Technologies). This commit supplement it.
    
    I note that there're two models produced by Mackie (Loud Technologies),
    which have the same name 'Onyx 1640i'. The former model based on OXFW970,
    the latter model based on Dice. This is probably due to low quality of
    communication of OXFW series.
    
    Additionally, the tester reports his or her experiences to get unexpected
    result at higher sampling transmission frequency as 88.2/96.0 kHz. We
    didn't have further investigation yet[0].
