Bug ID: 94804
   Summary: Major audio-video sync and audio dropout problems when
using Intel HDMI audio
   Product: PulseAudio
   Version: unspecified
  Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
  Severity: major
  Priority: medium
 Component: alsa
  Assignee: pulseaudio-bugs@lists.freedesktop.org
  Reporter: hancock...@gmail.com
QA Contact: pulseaudio-bugs@lists.freedesktop.org
CC: lenn...@poettering.net

I've got a machine using Intel Haswell integrated video with the HDMI1 output
connected to a monitor and HDMI2 connected to a Yamaha RX-V577 AV receiver
which is connected to a TV. This is using Fedora 23 and
pulseaudio-7.1-1.fc23.x86_64.

Whenever I have the audio output routed to "HDMI/DisplayPort 2" and try to play
a video in Firefox or Totem, the video appears to run too fast and the audio
becomes up to several seconds behind the video. The audio also keeps playing
for several seconds when pausing the video. When playing a video file in VLC,
it doesn't lose sync as much, but the audio cuts in and out, and in the VLC
debug log it has lots of complaints like this:

pulse debug: changing sink 2: alsa_output.pci-_00_03.0.hdmi-surround-extra1
(Built-in Audio Digital Surround 5.1 (HDMI 2))
pulse debug: started
core warning: picture is too late to be displayed (missing 25 ms)

core debug: auto hiding mouse cursor
core warning: timing screwed (drift: -80762 us): stopping resampling
core warning: playback too early (-81447): down-sampling
core warning: playback way too early (-120541): playing silence
core debug: inserting 5785 zeroes

VLC's audio output appears to work properly if I run VLC under pasuspender and
configure it to use ALSA audio output instead, so it seems like this is a
PulseAudio problem.

Not sure what more to do to debug this. I can provide more info if needed.

[pulseaudio-tickets] [Bug 94800] New: Automatically switch to HDMI profile when cable plugged in

[bugzilla-daemon]

https://bugs.freedesktop.org/show_bug.cgi?id=94800

Bug ID: 94800
   Summary: Automatically switch to HDMI profile when cable
plugged in
   Product: PulseAudio
   Version: unspecified
  Hardware: Other
OS: All
Status: NEW
  Severity: normal
  Priority: medium
 Component: modules
  Assignee: pulseaudio-bugs@lists.freedesktop.org
  Reporter: quentin.de...@gmail.com
QA Contact: pulseaudio-bugs@lists.freedesktop.org
CC: lenn...@poettering.net

I currently have to switch manually each time I plug my HDMI cable. It's a
cumbersome manual process that should happen automatically when HDMI cable is
plugged in:
- When HDMI cable is plugged in -> switch to Digital Stereo (HDMI) output
profile
- When unplugged, switch back to previous profile or to Analog Stereo Output

Note that I am talking about the _profiles_, on the _same_ audio card.

This mean you need pulseaudio say your active port selection and restore the
selected port after reboot to change alsa analog output switch as your sound
cannot detect headphone is plugged

One some audio cards like the AV200/virtuoso (Asus Xonar Essence), there
 is an option to switch the Analog out between headphones, line-out and
 front panel output.

 It is natural and more user friendly if users can have this option under
 Output and Settings for the selected device.


;;; 'Analog Output'

[Element Analog Output]
enumeration = select

[Option Analog Output:Speakers]
name = output-speaker
priority = 10

[Option Analog Output:Headphones]
name = output-headphones
priority = 9

[Option Analog Output:FP Headphones]
name = output-headphones
priority = 8

Is your question for me?

At the moment I am waiting for alsa mailing list subscription confirmation. As
soon I receive it, I will send a message there and write here the URL of it.
