      ALSA: oxygen: fix distorted output on AK4396-based cards · df91bc23
      Clemens Ladisch authored
      When changing the sample rate, the CMI8788's master clock output becomes
      unstable for a short time.  The AK4396 needs the master clock to do SPI
      writes, so writing to an AK4396 control register directly after a sample
      rate change will garble the value.  In our case, this leads to the DACs
      being misconfigured to I2S sample format, which results in a wrong
      output level and horrible distortions on samples louder than -6 dB.
      
      To fix this, we need to wait until the new master clock signal has
      become stable before doing SPI writes.
