Re: [alsa-devel] Front speakers doesn't work in multichannel output, regression in ALC888
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
You need pulseaudio lfe-filter for 2.1
http://cgit.freedesktop.org/pulseaudio/pulseaudio/log/?qt=grep&q=lfe-fil...
do you mean surround21 need 6 channel instead of channels with 5.1 internal /external speaker ?

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:
- 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.
auto mute only check headphone jack or line out jack but not those retasked mio jacks
- 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.
You need to switch "Channel mode" to "6 ch" if you need to use
external
5.1 speakers since you have 5.1 internal speakers
this change pin-ctl of headphone jack, mic jack and line in to OUT
post the output of alsa-info.sh
I always switched to "6 ch" through alsamixer. It always worked as
expected,
but recently I've got problems with it so it regressed somewhere.
My alsa-info.sh with "6 ch" set through alsamixer and "Analog output
surround
5.1 + Analog input stereo" set through KDE configuration module. http://www.alsa-project.org/db/?f=ff3f5a1f7f3e4662c3fa9bcf0158474a076b4cc4
With that I hear all channels except front left and front right.

it is still headphone jack with pin-ctl : 0xc0 OUT HP while mic jack and line in jack 's pin ctl are changed to 0x40 OUT
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 EAPD

To exclude that my speakers are broken or wrong connected: I get sound
from
front left and front right if i switch in KDE configuration module to
"Analog
duplex stereo", but then I get no sound from rest of my speakers.
http://cgit.freedesktop.org/pulseaudio/pulseaudio/tree/src/modules/alsa/mixe...
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
KDE configuration module lets me choose "connector" configuration but
only in
stereo mode. In stereo mode I can choose between "headphones" and "speakers". If it is set to "headphones" I hear sound in front left and front right speakers. If it is set to "speakers" I hear sound in rear left and rear right
speakers.
you need to switch "channel mode" to "2 ch" if you want to use your 5.1 internal speaker

There are difference between static model and generic parser
