Front speakers doesn't work in multichannel output, regression in ALC888

Front speakers doesn't work in multichannel output, regression in ALC888

[Łukasz Wojniłowicz]

Hi all,

My problem is that when I set channel output to "Analog output surround 5.1" 
(or 2.1 or 4.1), I hear no sound in front speakers, but in case of 5.1 or 4.1 
I can hear sound in rear speakers. I use kernel 3.19.5 and it didn't happen in 
earlier kernels that is 3.18 and in 3.17 for sure.

My configuration is:
OS: Fedora 21 64 bit
SoundCard: ALC888
Model name: acer-aspire-4930g
Laptop: Acer Aspire 5930g
Speakers: external 5.1 with 3 jacks
Sound channel configuration module is standard configuration module from KDE.

Additional info:
1) When channel output is 5.1 and I unplug green jack and leave two others 
jacks connected then I can hear sound in laptop internal speakers.
2) Earlier (kernel 3.18 and 3.17) I didn't have possibility to choose 2.1 
configuration and additionally to 4.1 configuration I could also choose 4.0 
configuration.

Thanks for looking into problem.

Cheers
LW

I don't remember any relevant change...  Could you try git bisect?

this change pin-ctl of headphone jack, mic jack and line in to OUT

You need pulseaudio lfe-filter for 2.1

http://cgit.freedesktop.org/pulseaudio/pulseaudio/log/?qt=grep&q=lfe-filter

do you mean surround21 need 6 channel instead of channels with 5.1 internal
/external speaker ?

auto mute only check headphone jack or line out jack but not those retasked

it is still headphone jack with pin-ctl : 0xc0 OUT HP while mic jack and

channel mode only change two mio jacks from IN to OUT

May need to use add_out_jack_mode=1 instead of add_jack_modes=1 when there
are Mic and line in jacks

Use Headphone Jack Mode control to switch HP to Line Out for pin-ctl and

pulseaudio mute external center/lfe controls when headphone jack is plugged
since pulseaudio not aware that the role of headphone has been changed


[Element Center]
switch = off
volume = off

[Element LFE]
switch = off
volume = off

you need to switch "channel mode" to "2 ch" if you want to use your 5.1
internal speaker

Seem only two pairs of stereo speakers and internal subwoofer at left
channel before this patch

The driver use more than two channels only after David 's patch

But all internal speakers of the notebook are at front of  the user, The 3D
sound effect is quite different from your external 5.1 speakers

Do you mean your 5930g need champ {FL FR RL RR LFE }?

This can be easily implemented by using "swap center/lfe" switch for those
codec support R/L swap

http://git.alsa-project.org/?p=alsa-lib.git;a=blob_plain;f=test/chmap.c;hb=HEAD

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

If codec does not support R/L swap, your 4.1 swap chmap need 5.0 routing

Do you expect pulseaudio show 4.1 swap(5.0) profile for internal speakers
and 4.1 and 5.1 profiles for external speakers ?

c3e837bbcc03e39991da5dd1f791c0 6cde9f7a45

As your patch indicate internal subwoofer use external center speaker
channel and your codec does not support L/R swap

You may need to reserve Audio mixer 0x26 for internal subwoofer playback
volume by restrict the connection of the internal rear speaker

excluding 0x26 so that last DAC can be assigned to the internal subwoofer
similar to alc889_fixup_dac_route

void alc888_fixup_dac_route(struct hda_codec *codec,
   const struct alc_fixup *fix, int action)
{
if (action == ALC_FIXUP_ACT_PRE_PROBE) {

hda_nid_t conn1[4] = { 0x0c, 0x0d, 0x0e, 0x0f};

snd_hda_override_conn_list(codec, 0x17, 4, conn1);

} else if (action == ALC_FIXUP_ACT_PROBE) {
conn[5] = { 0x0c, 0x0d, 0x0e, 0x0f, 0x26 };
snd_hda_override_conn_list(codec, 0x17, 5, conn);

Seem  4.1 is not defined in snd_pcm_std_chmap and you need to define and

How do the driver implement channel map when codec has  swap center/lfe

Do chnmap contain both {FL FR RL RR FC LFE} and {FL FR RL RR LFE FC} ?

Do headphone get same volume level when the jack is configured as Line Out
(without enable Headphone Amplifier) ?

The driver use different automute method when the jack is configured as HP
and Line Out

https://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/commit/sound/pci/hda?id=e0d32e335fc0e354db93a807736243f5035fbc67

http://cgit.freedesktop.org/pulseaudio/pulseaudio/tree/src/modules/alsa/mixer/paths

if you look at speaker.conf , lineout.conf and headphone.conf, it seem
pulseaudio is unlikely mute all internal speakers when one pair of the
playback volume control need to be shared by internal speaker and external
speakers

you need dirver 's automute instead of pulseaudio 's automute

http://git.alsa-project.org/?p=alsa-utils.git&a=search&h=HEAD&st=commit&s=chmap

do chmap of internal speakers need {FL FR RL RR LFE NA} ?

http://git.alsa-project.org/?p=alsa-lib.git&a=search&h=HEAD&st=commit&s=chmap

as set_chmap() still not yet implemented in pcm_route.c

do speaker-test need to specify channel map when using those odd number
channels ?

speaker-test -D surround21  -c3 -t wav
speaker-test -D surround41  -c5 -t wav -mFL,FR,RL,RR,LFE

Can chmap contain two _FIXED maps of same number of channels ?

Well, the driver should provide the correct chmap.

You are getting an error?
If so, that is expected if the underlying device does not support the
wanted channel map.

This is different from 2.1 internal speakers when yours also support
external 5.1

Seem only those idt codecs which wcaps support R/L swap but hda-intel use
snd_pcm_std_chmap

Are there any other sound card support swap front right and front left ?

This is common to all notebook using headphone jack and two other jacks to

Are there any side effect if you change the headphone jack to Line Out jack
as the jack no longer enable HP amp ?


use add_out_jack_modes for create Headphone/Line Out jack mode control to
change Headphone to Line Out and vice versa

You have to provide pulseaudio verbose log

If driver create channel mode which allow you to support surround5.1 with
your headphone,  line in and mic jack

It is possible for pulseaudio mute two of your external 5.1 speaker when
headphone jack is plugged

You have to determine which node 0x16 or 0x17 is your subwoofer and remove
the redundant speaker pin fixup

After remove the redundant internal speaker, 5.1 is only available after
you change the channel mode

Can  alsactl restore the channel mode before pulseaudio probe the sound
cards ?

Auto mic select is not enabled when the notebook has mic jack and line in
jack , internl mic

As jack retasking is specific to snd-hda-intel and some multi cjannel ac97
codecs

It is not easy to force pulseaudio to stop all client connection, reprobe
the profiles on board audio after jack retasking

hdajackretask also perform the same function
stop pulseaudio and using dynamic reconfiguration/early patching

For those notebook with headphone spdif combo jack, it need a customised
iec958.conf and you can use headphone jack to make iec958 unavailable

http://cgit.freedesktop.org/pulseaudio/pulseaudio/tree/src/modules/alsa/mixer/paths/iec958-stereo-output.conf

You need to define your 2.1 chmap if the subwoofer only use left channel

Are you sure that it is alsa driver bug since pulseaudio seem not using
line out jack to mute internal speakers ?


by adding new hint alt_config , you can use alt_config to select different
