      ALSA: usb: handle descriptor with SYNC_NONE illegal value · 395ae54b
      Pierre-Louis Bossart authored
      The M-Audio Transit exposes an interface with a SYNC_NONE attribute.
      This is not a valid value according to the USB audio classspec. However
      there is a sync endpoint associated to this record. Changing the logic to
      try to use this sync endpoint allows for seamless transitions between
      altset 2 and altset 3. If any errors happen, the behavior remains the same.

      ALSA: usb: fix corrupted pointers due to interface setting change · 63018447
      Pierre-Louis Bossart authored
      When a transition occurs between alternate settings that do not use the
      same synchronization method, the substream pointers were not reset.
      This prevents audio from being played during the second transition.
      
      Identified and tested with M-Audio Transit device
      (0763:2006 Midiman M-Audio Transit)
      
      Details of the issue:
      
      First playback to adaptive endpoint:
      $ aplay -Dhw:1,0 ~/24_96.wav
      Playing WAVE '/home/plb/24_96.wav' : Signed 24 bit Little Endian in 3bytes,

      Playing WAVE '/home/plb/16_48.wav' : Signed 16 bit Little Endian,
      Rate 48000 Hz, Stereo

      [ 3239.484606] usb 1-2: Setting params for ep #83 (type 1, 4 urbs), ret=0
      
      This last line shows that a sync endpoint is used when it shouldn't.
      The sync endpoint is no longer valid and the pointers are corrupted

      ALSA: hda - Fix pin config and mapping on Alienware 15 · fe14f39e
      Takashi Iwai authored
      Alienware 15 has CA0132 codec for its onboard sound, but the pin
      config and mapping seem quite different from other Creative boards.
      This patch corrects them, at least, for providing the right headphone
      and mic jack notification, as well as removing the non-existing SPDIF
      pins.
      
      Even with this fix, not all stuff works perfectly yet, mainly because
      of the badly written ca0132 driver code -- it has too many implicit
      assumptions of pin configs and maps.  Nevertheless, this is a small
      good step forward.

      ALSA: echoaudio: Use standard C definitions of true and false · 3f6175ec
      Mark Brown authored
      The echoaudio locally defines TRUE and FALSE.  Not only is this
      redundant given that C now has a boolean type it results in lots of
      warnings as other headers also define these macros, causing duplicate
      definitions.  Fix this by removing the local defines and converting all
      local users to use the standard C true and false instead, simply
      removing the macros is less safe due to implicit inclusion of the other
      definitons.
