Merge remote-tracking branch 'shariman/wmall'

* shariman/wmall:
  Fix audio output
  Suppress dumping of residues buffer
  Use quantizer value read from bitstream
  Cosmetics: Remove two empty lines and realign some code
  Reset acfilter_prevvalues buffer in clear_codec_buffers()
  Fix AC filter buffers and AC filter reversion
