Headphones are gone with kernel 4.8.1

[victrcodes]

I've upgraded straight from kernel 4.4 to 4.8, followed the section "Users upgrading from pre-4.7 Samus kernel". Everything is working, but headphones are gone from the sound settings. If I reboot back to kernel 4.8 without doing any changes - headphones are back, but now the mic is gone, probably due to the "Users upgrading from pre-4.7 Samus kernel" changes. Am I missing something here? I'm on Ubuntu 16.04.

Ditto. I'm having the same problem with no headphones listed after removing the following lines from /etc/pulse/default.pa:

#load-module module-alsa-sink device=hw:0,0
#load-module module-alsa-source device=hw:0,1
#load-module module-alsa-source device=hw:0,2

I know that the bdw-rt5677 driver is included in the latest kernel, but the headphone jack does not seem to be dynamically located and loaded without modifying /etc/pulse/default.pa.

Was this ever fixed? I'm on the latest samus kernel and I don't have headphones, which is kind of problematic (since I use headphones on my laptop far more than my speakers).

[raphael]

The scripts in the README work fine for me, I can use them to switch between headphones and speakers.

[nsparks86]

Has anyone made a script to toggle this with a single action?

[victrcodes]

@nsparks86 there's nothing to toggle if headphones are not even loaded with latest kernel. I tend to agree with what @nelsonni said.

[rroll1]

The script to toggle is in the readme, or at least, the commands. Here are the scripts I use to switch between headphones and speakers, based on @raphael's comment a week ago:

 $ cat /usr/sbin/samus-alsaenable-speakers 
 #!/bin/sh
 #

 ## enable audio
 amixer -c 0 cset name='DAC1 MIXL DAC1 Switch' on
 amixer -c 0 cset name='DAC1 MIXR DAC1 Switch' on

 ## enable speakers
 amixer -c 0 cset name='Headphone Switch' off
 amixer -c 0 cset name='Stereo DAC MIXL DAC1 L Switch' off
 amixer -c 0 cset name='Stereo DAC MIXR DAC1 R Switch' off
 amixer -c 0 cset name='Stereo DAC MIXL DAC1 R Switch' on
 amixer -c 0 cset name='Stereo DAC MIXR DAC1 L Switch' on
 amixer -c 0 cset name='Speaker Switch' on

 $ cat /usr/sbin/samus-alsaenable-headphones 
 #!/bin/sh
 # 
 ## enable audio
 amixer -c 0 cset name='DAC1 MIXL DAC1 Switch' on
 amixer -c 0 cset name='DAC1 MIXR DAC1 Switch' on

 ## enable speakers
 amixer -c 0 cset name='Speaker Switch' off
 amixer -c 0 cset name='Stereo DAC MIXL DAC1 R Switch' off
 amixer -c 0 cset name='Stereo DAC MIXR DAC1 L Switch' off
 amixer -c 0 cset name='Stereo DAC MIXL DAC1 L Switch' on
 amixer -c 0 cset name='Stereo DAC MIXR DAC1 R Switch' on
 amixer -c 0 cset name='OUT1 Playback Switch' on
 amixer -c 0 cset name='OUT2 Playback Switch' on
 amixer -c 0 cset name='Headphone Switch' on

This works for me on

$ uname -a

Haven't updated to 4.8.7 yet.

There are 2 issues currently, though neither of them are the headphones not working:

1. Headphones don't show up in the Gnome Sound control panel, it only registers the speakers in that list. I believe that in earlier Samus kernels it showed up as an output device in the Sound control panel; now you have to use the amixer commands to switch.
2. ACPI doesn't detect headphone plugs or unplugs, so it's impossible at the current moment to bind the scripts to ACPI events. Hopefully this will be fixed sometime in the future (maybe .7? Haven't installed it yet)

[nsparks86]

I'm not very familiar with Bash scripting, but I figured I'd try and start somewhere. Could use a "Headphone/Speaker toggle" script, so I came up with these lines to determine the current state.

awk -F"[][]" '/Playback/ { print $2 }' <(amixer sget Speaker)
awk -F"[][]" '/Playback/ { print $2 }' <(amixer sget Headphone)

maybe stupid question: I am on KDE on Arch, still on my first install from April '15.
Is everybody here using plain ALSA? Who has pulseaudio? I feel like my audio setup became a mess, especially looking into my mixer. Was also thinking of a fresh install, as I still wanted to update my ssd firmware eventually.

Anybody with KDE/Pulseaudio + the script and everything just works? And how many mixer items do you have? :-)

[stefanwiegmann]

I guess I was kind of hijacking this thread, but I did my fresh install. Only thing I had to do was running the sound scripts @raphael provided and everything worked as you would expect. My mess was due to still tinkering in my first install from over a year ago and with so many changes happening.....

As for the headphone/speaker switch: I would love acpi to work as well, but in the meantime I just put a toggle script on CTRL+[Volume Mute]. The script checks the current setup and switches with @raphael 's sound scripts accordingly.

[raphael]

Do you know if ACPI works with the vanilla 4.9 kernel?

[stefanwiegmann]

short answer: no.

I am not an acpi guy. would have to read up on it. I thought I read somewhere here acpi doesn't work in general for us. Is there a module we are missing or what did @rroll1 mean?

I'll check 4.9 as soon as I get it

[stefanwiegmann]

by the way, your current aur script doesn't build ;-)

[raphael]

Fixed it, thanks.
