headphone jack sense not enabled

[Israel Dahl]

bug is present in Ubuntu 12.04 and Xubuntu 12.04 and Lubuntu 12.04.1 64bit
alsa-base 1.0.25+dfsg-0ubuntu1 on this machine (64 bit)
I except Ubuntu to automatically sense the presence of headphones and disable the speakers. This is not the case, the speakers and headphones play simultaneously. I must install gnome-alsamixer to manually set the jack sense. Alsa should have this enabled as the default setting. This seems as though it should be a very easy bug to fix, though.

I basically have a generic Dell box with integrated ICH7 audio

 0 [ICH7 ]: ICH4 - Intel ICH7
                      Intel ICH7 with AD1981B at irq 23

When I plug my headphones into the front, in alsamixer only the Headphone slider has an effect, Master does nothing to change volume.

Now Pulseaudio somehow merges these (even if flatvol is off) and the whole range of Headphone is compressed into the low range and it gets painful very quickly.

No idea if this is ALSA bug or not. Please advise and forward accordingly.

Have you had time to look at this yet, Maarten?

You've told me to poke you.

[Colin Guthrie (launchpad-colin)]

I think this is expected behaviour...

Can you attach output of "pacmd ls"?

Normally I'd expect a "Headphones" port to be available for your Sink. With the jack detection capabilities added in PA 2.0, this port will hopefully now be activated automatically when a jack is plugged in. In older versions you have to enable the port manually in pavucontrol or another mixer when you plug in a jack.

pacmd ls

Attached »pacmd ls«. (Note I have an Apple Monitor with USB audio too)

It’s not expected behaviour that when I use my volume buttons that only the two lowest ticks give me a range between threshold-of-hearing and thresold-of-pain, is it?

 |0---xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx|

0 nothing, x == pain

I don’t have a headphone port. It’s not there. And on IRC mkbosman told me he had the same problem and to open this bug.

You appear to have two Headphone related ports available along with a couple others:
 * Headphones / Amplifier
 * Headphones / No Amplifier

ports:
 analog-output-headphones;output-amplifier-on: Headphones / Amplifier (priority 9010, available: unknown)

 analog-output-headphones;output-amplifier-off: Headphones / No Amplifier (priority 9000, available: unknown)

 analog-output-lfe-on-mono;output-amplifier-on: LFE on Separate Mono Output / Amplifier (priority 4010, available: unknown)

 analog-output-lfe-on-mono;output-amplifier-off: LFE on Separate Mono Output / No Amplifier (priority 4000, available: unknown)

What is interesting is that you do not have any "Analog Speakers" ports listed. I think we're addressing this shortly in PA master having spoken to David (I can tell you're using Ubuntu from the patches), so this is good, but I'm not sure why Master is getting adjusted here... I'd have expected the two headphone ports to adjust Headphones and Line respectively.

Ultimately, this basically boils down to writing a profile for the hardware. I'd have hoped the default profiles would have sufficed and perhaps it still can once the speakers port comes in.

For more info on writing profiles see:
http://www.freedesktop.org/wiki/Software/PulseAudio/Backends/ALSA/Profiles

I've CC'ed David to get his input here.

That's an ALSA driver bug. Unfortunately I don't know how to fix AC'97s.

> What is interesting is that you do not have any "Analog Speakers" ports listed.

There does not seem to be any kcontrols indicating that you have speakers, therefore no "Analog Speakers" port.

It seems to me that if "Master" controls the speaker but not the headphones, "Master" should be renamed to "Speaker".

Not sure what that means.... Does that mean there is no fix, it is already "fixed" since some devices need it off? Shouldn't the devices that need it off be specifically blacklisted, or is that not possible?

Ok, so it is in the whitelist already, well... for some reason the first time I used the headphones it blared through the speakers as well, so even though it is supposed to be whitelisted for jack sense that DID NOT occur. I had to manually turn on the headphone jack sense by using the program gnome-alsamixer and checking the headphone jack sense checkbox. I don't know what alsactl restore is at all, sorry. Once I have checked the headphone jack sense box in the gnome-alsamixer program the headphone jacksense remains in effect every time I use it. I had to enable it the very first time. Now it is enabled. It should be enabled by default (as new users might not know they can install a program to enable it)

MASTER VOLUME REGISTER Index 0x02

 This register controls the Line_Out volume controls for both stereo channels and the mute bit. Each volume subregister contains five bits, generating 32 volume levels with 31 steps of 1.5 dB each. Because AC ’97 defines 6-bit volume registers, to maintain compatibility whenever the D5 or D13 bits are set to 1, their respective lower five volume bits are automatically set to 1 by the codec logic. On readback, all lower five bits read 1s whenever these bits are set to 1. Refer to Table 12 for examples.

it is unlikely fix in alsa driver as pulseaudio expect jack detection kctl

although js0 ST or js1 ST of ac97 register 0x72 of ad1981b may reflect hp status

it is not clear how and when to check the change in jack state by timer or interrept

[Raymond (superquad-vortex2)]

Table 40. Bit Mnemonic JS0 Interrupt Function JS1 TMR JS0 TMR JS1 MD JS0 MD JS1 ST JS0 ST JS1 INT JS0 INT 0x0000

JS1INT JS0ST JS1ST JS0MD JS1MD JS0TMR JS1TMR JS0EQB JS1EQB JSMT [2:0]

JS0INT
This bit indicates that Pin JS0 has generated an interrupt. This bit remains set until the software services the JS0 interrupt, that is, JS0 ISR should clear this bit by writing a 0 to it. The interrupt to the system is an OR combination of this bit and JS1INT. The actual interrupt implementation is selected by the INTS bit (Register 0x76). It is also possible to generate a software system interrupt by writing a 1 to this bit.

Js1 Interrupt
This bit indicates that Pin JS1 has generated an interrupt. This bit remains set until the software services the JS1 interrupt, that is, JS1 ISR should clear this bit by writing a 0 to it. See the JS0INT description for details.

JS0 State
This bit always reports the logic state of the JS0 pin.

JS1 State
This bit always reports the logic state of the JS1 pin.

JS0 Mode
This bit selects the operation mode for the JS0 pin. 0 = Jack sense mode (default). 1 = Interrupt mode.

JS1 Mode
This bit selects the operation mode for the JS1 pin. 0 = Jack sense mode (default). 1 = Interrupt mode.

JS0 Timer Enable
If this bit is set to 1, JS0 must be high for >278 ms to be recognized.

JS1 Timer Enable
If this bit is set to 1, JS1 must be high for >278 ms to be recognized.

 JS0 EQ Bypass Enable
This bit enables JS0 to control the EQ bypass. When this bit is set to 1, JS0 = 1 causes the EQ to be bypassed.

JS1 EQ Bypass Enable
This bit enables JS1 to control the EQ bypass. When this bit is set to 1, JS1 = 1 causes the EQ to be bypassed.

JS Mute Enable Selector

These three bits select and enable the jack sense muting action (see Table 41

these two controls only change JSMT2 and JSMT1

you need bit 2 and bit3 of AC97_AD_JACK_SPDIF for JS0 ST and JS1 ST

Hi, I am also trying to get internal speakers to work on Dell OptiPlex GX620 (model no.: DCCY). External speakers work, however internal speakers are not even listed in PulseAudio Volume Control (and there is no sound). The internal speakers worked on previous OS (Windows XP).

do you mean your desktop have stereo internal speakers since ad1981b only has three output

line out
hp
mono out

and your dell gx520 seem have hp at front and line out at rear

Small error on my part: I have OptiPlex GX520, not GX620. Should be similar though. Attaching my alsa-info.

js1 st and js0 st seem to be clear , mono out is not muted by FMUTE

as desktop speaker.conf has beem merged

if your desktop speaker use mono out playback volume/switch

you have to add element master mono to speaker.conf

ad1981b - add jack detect kctl

This patch still lack the interrupt to call ad198x_handle_hp_jack() and ad198x_handle_lo_jack() when hp or line out is plugged

[Raymond (superquad-vortex2)]

you will also need to schedule the driver to call ad198x_handle_hp_jack and ad198x_handle_lo_jack in intel8x0.c periodically similar to hda vt1708 codec

however ad1981b is also used in notebook or desktop

this mean that you need to differentitate desktop and notebook

most likely you need pulseaudio to adjust the element in speaker path in alsa-mixer.c if notebook use master for the speaker

another problem is external amplifier defined in

[Element External Amplifier]
switch = select

[Option External Amplifier:on]
name = output-amplifier-on
priority = 10

[Option External Amplifier:off]
name = output-amplifier-off
priority = 0

you have to determine it affect which output paths

post the output of

check whether bit 0 of the global status of your ich controller change when you enable js interrupt by set js1 mode of ac97 registers using echo

card*/codec97#*/ac97#?-?
 Shows the general information of this AC97 codec chip, such as
 name, capabilities, set up.

card*/codec97#0/ac97#?-?+regs
 Shows the AC97 register dump. Useful for debugging.

 When CONFIG_SND_DEBUG is enabled, you can write to this file for
 changing an AC97 register directly. Pass two hex numbers.
 For example,

 # echo 02 9f1f > /proc/asound/card0/codec97#0/ac97#0-0+regs

card*/codec97#0/ac97#?-?+regs
  Shows the AC97 register dump. Useful for debugging.

 recompile alsa driver with CONFIG_SND_DEBUG is enabled, you can write to this file for
  changing an AC97 register directly.

Pass two hex numbers.
  For example,

 # echo 02 9f1f > /proc/asound/card0/codec97#0/ac97#0-0+regs

this change master playback volume register

with headphone unplugged

set js1 mode bit of ac97 register 0x72

echo 72 1824 > /proc/asound/card0/codec97#0/ac97#0-0+regs

plug headphone

cat /proc/asound/card0/intel8x0

check bit 0 of global status is set or not

repeat the test with line out by set js0 mode

if gpi bit of global status was set after jack is plugged

we need to add a check of this bit in snd_intel8x0_interrupt and call those ad198x_handle_jp_jack
