      ALSA: ctxfi - fix PTP address initialization · 21956b61
      Jaroslav Kysela authored
      
      After hours of debugging, I finally found the reason why some source
      and runtime combination does not work. The PTP (page table pages)
      address must be aligned. I am not sure how much, but alignment to
      PAGE_SIZE is sufficient. Also, use ALSA's page allocation routines
      to ensure proper virtual -> physical address translation.

      ALSA: hda - Fix mute led GPIO on HP dv-series notebooks · d38cce70
      Kunal Gangakhedkar authored
      
      On my laptop (HP dv6-1110ax), there are no OEM strings in SMBIOS of type
      "HP_Mute_LED*". Hence, the GPIO for the mute button LED doesn't get set
      properly. I didn't find the strings in my cousin's laptop (HP dv9500t CTO)
      either.
      
      As per the documentation of find_mute_led_gpio(), these strings occur
      in HP B-series systems - so, before scanning the SMBIOS strings, we need to
      check if we're dealing with a B-series system.
      Need to get confirmation from HP if this logic takes care of all the
      systems. I'm trying to poke a friend there.

      ALSA: hda - use snd_hda_jack_detect() again in patch_sigmatel.c · a252c81a
      Takashi Iwai authored
      
      Use snd_hda_jack_detect() again for jack-sensing.
      The triggering problem can be worked around with codec->no_trigger_sense
      flag now.

      ALSA: hda - Disable tigger at pin-sensing on AD codecs · 729d55ba
      Takashi Iwai authored
      
      Analog Device codecs seem to have problems with the triggering of
      pin-sensing although their pincaps give the trigger requirements.
      Some reported that constant CPU load on HP laptops with AD codecs.
      
      For avoiding this regression, add a flag to codec struct to notify
      explicitly that the codec doesn't suppot the trigger at pin-sensing.

      ALSA: hda - HDMI sticky stream tag support · ef18bede
      Wu Fengguang authored
      
      When we run the following commands in turn (with
      CONFIG_SND_HDA_POWER_SAVE_DEFAULT=0),
      
      	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).
