Bug 68286

http://www.intel.com/support/motherboards/desktop/sb/CS-034206.htm


to enable multi streaming, you have to use hints indep_hp=true

instead of retasking line in as another headphone

need the conference application allow you to select alt analog playback device

Hint Strings
~~~~~~~~~~~~
The codec parser have several switches and adjustment knobs for
matching better with the actual codec or device behavior.  Many of
them can be adjusted dynamically via "hints" strings as mentioned in
the section above.  For example, by passing `jack_detect = no` string
via sysfs or a patch file, you can disable the jack detection, thus
the codec parser will skip the features like auto-mute or mic
auto-switch.  As a boolean value, either `yes`, `no`, `true`, `false`,
`1` or `0` can be passed.

The generic parser supports the following hints:


- indep_hp (bool): provide the independent headphone PCM stream and
  the corresponding mixer control, if available


http://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/plain/Documentation/sound/alsa/HD-Audio-Controls.txt

* Independent HP
  When this enum control is enabled, the headphone output is routed
  from an individual stream (the third PCM such as hw:0,2) instead of
  the primary stream.

Ah interesting. Raymond, do you want me to try this and see if PA behaves differently?

Can you provide a link to this? I googled but could not find anything relevant. Is this a PA utility?

in addition to disable automute , you need is change pulseaudio do not mute front, surround, center and lfe in


http://cgit.freedesktop.org/pulseaudio/pulseaudio/plain/src/modules/alsa/mixer/paths/analog-output-headphones.conf

if webrtc, audacity and aplay -L use snd_device_name_hint to get list of playback and capture devices

just add device 2 for alt analog playback and capture device of desktop using hda intel


HDA-Intel.pcm.frontpanel.0 {
	@args [ CARD ]
	@args.CARD {
		type string
	}
	slave.pcm {
		type hw
		card $CARD
          device 2
	}
}

I added indep_hp=true. I don't see any difference.

I don't see any device 2 control, but to be honest I don't really understand what to do.

Here is the output of aplay -l and aplay -L with the indep_hp=true.

how did you add the hint ?

use early patching 

or

hda_generic.c


int snd_hda_gen_parse_auto_config(struct hda_codec *codec,
				  struct auto_pin_cfg *cfg)
{
	struct hda_gen_spec *spec = codec->spec;
	int err;
+
+       /* for HDA codecs support 7.1+2  */
+       if ((cfg->line_outs == 4) && (cfg->hp_outs == 1))
+             spec->indep_hp = 1;

	parse_user_hints(codec);




http://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/plain/Documentation/sound/alsa/HD-Audio.txt



Early Patching
~~~~~~~~~~~~~~
When CONFIG_SND_HDA_PATCH_LOADER=y is set, you can pass a "patch" as a
firmware file for modifying the HD-audio setup before initializing the
codec.  This can work basically like the reconfiguration via sysfs in
the above, but it does it before the first codec configuration.

A patch file is a plain text file which looks like below:

------------------------------------------------------------------------
  [codec]
  0x12345678 0xabcd1234 2

  [model]
  auto

  [hint]
  indep_hp = true
------------------------------------------------------------------------

The file needs to have a line `[codec]`.  The next line should contain
three numbers indicating the codec vendor-id (0x12345678 in the
example), the codec subsystem-id (0xabcd1234) and the address (2) of
the codec.  The rest patch entries are applied to this specified codec
until another codec entry is given.  Passing 0 or a negative number to
the first or the second value will make the check of the corresponding
field be skipped.  It'll be useful for really broken devices that don't
initialize SSID properly.

The `[model]` line allows to change the model name of the each codec.
In the example above, it will be changed to model=auto.
Note that this overrides the module option.


The hd-audio driver reads the file via request_firmware().  Thus,
a patch file has to be located on the appropriate firmware path,
typically, /lib/firmware.  For example, when you pass the option
`patch=hda-init.fw`, the file /lib/firmware/hda-init.fw must be
present.

The patch module option is specific to each card instance, and you
need to give one file name for each instance, separated by commas.
For example, if you have two cards, one for an on-board analog and one 
for an HDMI video board, you may pass patch option like below:
------------------------------------------------------------------------
    options snd-hda-intel patch=on-board-patch,hdmi-patch
------------------------------------------------------------------------

Thanks Raymond, I added indep_hp via early patching and now I do have a second "alt analog" device 2:

$  aplay -l
**** List of PLAYBACK Hardware Devices ****
card 1: PCH [HDA Intel PCH], device 0: ALC898 Analog [ALC898 Analog]
  Subdevices: 0/1
  Subdevice #0: subdevice #0

  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: PCH [HDA Intel PCH], device 2: ALC898 Alt Analog [ALC898 Alt Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

I am confused about comment #5 however. Where is this configuration supposed to go? It looks like alsa configuration and I added it to /etc/asound.conf but as far as I can tell it didn't change anything.

if the application use  snd_device_name_hint and snd_device_name_get_hint to obtain the device name

http://www.alsa-project.org/alsa-doc/alsa-lib/group___control.html

it is possible to add for the alt analog device 2 for hda-intel

as you also have alt analog capture device and alt analog playback device for the front audio panel

http://git.alsa-project.org/?p=alsa-lib.git;a=tree;f=src/conf/pcm;hb=HEAD






you can get all hint when you turn on defaults.namehin.showall or show extended hint when you turn on defaults.namehint.extended 


http://git.alsa-project.org/?p=alsa-lib.git;a=blob;f=src/conf/alsa.conf;hb=HEAD

Raymond, I'm sorry I don't understand comment #9. All the applications I use, such as KDE, Chrome and Skype simply send audio to PulseAudio. There are no "device selections" in any of these applications as far as I can tell.

With the indep_hp setting, I am able to switch between speakers and headphones by using alsamixer to change the card hardware controls:

amixer -c 1 sset 'Speaker' 100                                                                                                                                                                                                                                                               
amixer -c 1 sset 'Headphone',1 0    

But is there a way to tell PulseAudio to do the above?

Toggling between speakers and headphones should be trivial (in theory) by just changing the sink port. But before going into more detail, could you attach the output of "pactl list"?

[    4.077762] ALSA sound/pci/hda/hda_intel.c:3742 0000:00:1b.0: Applying patch firmware 'hda-jack-retask.fw'

Output of `pactl list`

I have attached the output of `pactl list` as requested.

If I have understood correctly, there are two problems:

1. The headphone jack detection isn't working properly (it's showing up as "unavailable" even when the headphones are plugged in).

2. Pulseaudio doesn't really support using the headphones and speakers at the same time.

In the ideal work the alsa driver or pulseaudio (whichever is to blame) would be fixed to make the jack detection work, and a feature would be added to pulseaudio to make simultaneous output work out-of-the-box. I don't have time to work on either.

If I understood correctly, you primarily would like to have an easy way to switch between the headphones and the speakers, and secondarily you would like to have an easy way to enable output to both at the same time. I may have a workaround for the first goal:

Switching to headphones (two commands):

    pactl set-card-profile alsa_card.pci-0000_00_1b.0 output:analog-stereo+input:analog-stereo

    pactl set-sink-port alsa_output.pci-0000_00_1b.0.analog-stereo analog-output-headphones


Switching to speakers (two commands):

    pactl set-card-profile alsa_card.pci-0000_00_1b.0 output:analog-surround-40+input:analog-stereo

    pactl set-sink-port alsa_output.pci-0000_00_1b.0.analog-surround-40 analog-output

(In the last command the right port might also be "analog-output-speaker" instead of "analog-output", but I'm not sure if it really makes a difference anyway.)

Does that work?

Yes, that seems to be the case.

Switching rather than using both simultaneously is more important to me, but yes.

Yes, that would be ideal.

The first goal is what I am primarily interested in.

Running the above two commands results in no output at all. Either to my headphones or to my speakers (sound stops after the first command, and the second does not restore it).

> Switching to speakers (two commands):

This restores sound as it was before.

No. See above.

Yes, it does work with analog-output-speaker in the second command!

I think I simply had the headphones and rear speakers plugged into the wrong ports.

Thank you very much!

Specifically, this is what seems to work perfectly with my setup in order to have audio on either the speakers or the headphones, but not both:

Switch to speakers:

#!/bin/sh
amixer -c 1 sset "Auto-Mute Mode" Disabled
pactl set-card-profile alsa_card.pci-0000_00_1b.0 output:analog-surround-40+input:analog-stereo
pactl set-sink-port alsa_output.pci-0000_00_1b.0.analog-surround-40 analog-output-speaker
amixer -c 1 sset 'Speaker' 100
amixer -c 1 sset 'Headphone',1 0

Switch to headphones:

#!/bin/sh
# Leave Auto-Mute Mode on Disabled for output headphones + speakers
amixer -c 1 sset "Auto-Mute Mode" 'Line Out+Speaker'
pactl set-card-profile alsa_card.pci-0000_00_1b.0 output:analog-stereo+input:analog-stereo
pactl set-sink-port alsa_output.pci-0000_00_1b.0.analog-stereo analog-output
amixer -c 1 sset 'Speaker' 0
amixer -c 1 sset 'Headphone',1 100
