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
