      ALSA: pcm_native - fix runtime->boundary calculation · 7910b4a1
      Jaroslav Kysela authored
      The code in pcm_lib updating runtime->hw_ptr_interrupt expects
      that runtime->boundary is divisible with runtime->period_size.
      Thanks are going to Clemens Ladisch for the notice.
      Fix the runtime->boundary calculation using buffer_size * period_size
      as base and find a least common multiple for 32bit platforms when
      the expression might overflow.

      ALSA: pcm_lib - return back hw_ptr_interrupt · e7636925
      Jaroslav Kysela authored
      Clemens Ladisch noted for hw_ptr_removal in "cleanup & merge hw_ptr
      update functions" commit:
      "It is possible for the status/delay ioctls to be called when the sound
      card's pointer register alreay shows a position at the beginning of the
      new period, but immediately before the interrupt is actually executed.
      (This happens regularly on a SMP machine with mplayer.)  When that
      happens, the code thinks that the position must be at least one period
      ahead of the current position and drops an entire buffer of data."
      Return back the hw_ptr_interrupt variable. The last interrupt pointer
      is always computed from the latest hw_ptr instead of tracking it
      separately (in this case all hw_ptr checks and modifications might
      influence also hw_ptr_interrupt and it is difficult to keep it

      ALSA: hda - HDMI sticky stream tag support · ef18bede
      Wu Fengguang authored
      When we run the following commands in turn (with
      	speaker-test -Dhw:0,3 -c2 -twav  # HDMI
      	speaker-test -Dhw:0,0 -c2 -twav  # Analog
      The second command will produce sound in the analog lineout _as well as_
      HDMI sink. The root cause is, device 0 "reuses" the same stream tag that
      was used by device 3, and the "intelhdmi - sticky stream id" patch leaves
      the HDMI codec in a functional state. So the HDMI codec happily accepts
      the audio samples which reuse its stream tag.
      The proposed solution is to remember the last device each azx_dev was
      assigned to, and prefer to
      1) reuse the azx_dev (and hence the stream tag) the HDMI codec last used
      2) or assign a never-used azx_dev for HDMI
      With this patch and the above two speaker-test commands,
      HDMI codec will use stream tag 8 and Analog codec will use 5.
      The stream tag used by HDMI codec won't be reused by others, as long
      as we don't run out of the 4 playback azx_dev's. The legacy Analog
      codec will continue to use stream tag 5 because its device id is 0
      (this is a bit tricky).
