      ALSA: Enable SPDIF output on ALC655 · c872e8ca
      Takashi Iwai authored
      Some hardwares with ALC655 codec don't indicate the proper ext id bit
      for SPDIF output although it supports.  Force to enable the bit.

      ALSA: pcsp - Fix locking messes in snd-pcsp · 96c7d478
      Takashi Iwai authored
      snd-pcsp driver takes chip->substream_lock together with PCM substream
      lock.  These are even mixed up with hrtimer's lock, resulting in messy
      lock depencies.  Right now, snd-pcsp driver resolves the deadlock by
      using HRTIMER_CB_SOFTIRQ.  However, this isn't nice for a really fast
      path like bit-flipping.
      
      This patch introduces a tasklet for PCM period handling so that the
      hrtimer callback can be handled fast.  This also reduce the use of
      chip->substream_lock to avoid deadlocks.  It's still used in pointer
      callback, but even this could be removed with a proper barrier.
      
      Another good solution is to introduce async trigger callback.  But,
      this will involve with a major rewrite of the PCM core code, so I
      take first this easy fix.
