Subject: HDAudio and pulse audio
Date: Thu, 25 Apr 2019 16:50:32 +0800	[thread overview]
Message-ID: <ca0ffa32-dc13-6fbf-42d7-65ee7879f681@linux.intel.com> (raw)

Hi all,

         I am working on sound open firmware in ASoC to enable HDAudio 
with pulse audio in ubuntu.
         There is a HDAudio codec driver hdac_hda.c in ASoC, which 
invokes HDAudio functions defined
         in sound/pci/hda, for ASoC to utilize the HDAudio codec. Now I 
get a issue: pulse audio can't  detect
        headphone pluged or not.

         Could anyone help to tell me about Jack detection flow in 
HDAudio and how does HDAudio
         work with pulse audio ? Does HDAudio report a event to pulse 
audio when headphone detected ?
        As I know,  ASoC codec driver would invoke snd_soc_jack_report 
to notify user mode, how about HDAudio
        driver ?

Thanks!

Rander
