Sound output to headphones

Elimelech · Apr 2, 2023

freebsd 13.2 system

If you connect headphones, the sound continues to go to the laptop's speakers.
At random, I realized that if you stop the sound and write

Code:

#sysctl hw.snd.default_unit=2

then headphones will work, if 1 - speakers. Can I make it switch automatically?

Code:

# cat /dev/sndstat

Installed devices:

pcm0: <ATI R6xx (HDMI)> (play)

pcm1: <Realtek ALC236 (Analog)> (play/rec) default

pcm2: <Realtek ALC236 (Right Analog Headphones)> (play)

No devices installed from userspace.

Probably, but exactly how to do it will depend on your specific hardware. The 'EXAMPLES' section in snd_hda(4) describes how to do this for a Realtek ALC888; those instructions can likely be adapted to work for your card with a bit of experimentation.

Have a read of this thread

Solved - Getting sound to automatically switch to laptop headphone jack? (X1 Carbon 6th Gen ThinkPad Realtek ALC285)

I haven't been able to find a clear guide on this. Currently, when I plug in headphones, the speakers cut out. So it's obviously detecting it but no sound in headphones. Can't see any way to raise the volume on the headphones.

For some reason these settings don't work.

From what I read and understand, which I admit is not much, the 3 line should read:

hint.hdaa.0.nid33.config="as=1 seq=15 device=Headphones"

find the one that does not say Disabled, then use the line that says config to pull out the information for device.hints

Code:

added to /boot/device.hints

#Speaker
hint.hdaa.1.nid20.config="as=2 seq=0"

twllnbrck · Apr 2, 2023

Yes they should be in the same association (as=1). Then you have to fiddle with the "nid"s.
On my old Thinkpad I have this in my /boot/device.hints:

Code:

hint.hdaa.0.nid31.config="as=1 seq=0 device=Speaker"
hint.hdaa.0.nid25.config="as=1 seq=15 device=Headphones"

blackbird9 · Apr 2, 2023

I have this in my device.hints
hint.hdaa.0.nid31.config="as=1 seq=0 device=Speaker"
hint.hdaa.0.nid25.config="as=1 seq=15 device=Headphones"
which looks just the same as twiinbrck.

That's on a thinkpad X201. Works perfectly, switches over on plug in/out.

Elimelech · Apr 2, 2023

Or something to block KDE5? Since in the audio device settings themselves, sound cards are not switched in manual mode. Why?

blackbird9 · Apr 2, 2023

I got the same settings as twllnbrck on my thinkpad X201.

To figure out the nid's, dmesg | grep pcm gives the following two lines:-

pcm0: <Conexant CX20585 (Right Analog)> at nid 25 and 27 on hdaa0
pcm1: <Conexant CX20585 (Internal Analog)> at nid 31 and 35 on hdaa0

where "right analog" is the headphones (socket is on the right hand side of the box) and
"internal analog" is the internal speakers. Associating the two first nid values (ie 31 and 25) in the device hints forms the association. The two pairs of nids appear to map to the two stereo pairs, associating just the first channel of each pair is sufficient to get full stereo switchover, at least on this system.

So in /boot/device.hints we have:-

hint.hdaa.0.nid31.config="as=1 seq=0 device=Speaker"
hint.hdaa.0.nid25.config="as=1 seq=15 device=Headphones"

There is another detailed explanation here for a machine with a rtl sound chip:-

FreeBSD: no automatic switching between sound in speaker and built-in headphones jack

I have a Lenovo Ideapad 100S 14'' IBR-14'' Intel Celeron CPU N3060 @ 1.60GHz, 32GB SSD, 4GB RAM, with a Realtek ALC269 as the chip sound. The machine is running FreeBSD 12.0; I have managed to setup

Elimelech · Apr 2, 2023

Code:

root@F3ja:/usr/home/luba # dmesg | grep pcm

pcm0: <ATI R6xx (HDMI)> at nid 3 on hdaa0

pcm1: <Realtek ALC236 (Analog)> at nid 20 and 25 on hdaa1

pcm2: <Realtek ALC236 (Right Analog Headphones)> at nid 33 on hdaa1

pcm0: <ATI R6xx (HDMI)> at nid 3 on hdaa0

pcm1: <Realtek ALC236 (Analog)> at nid 20 and 25 on hdaa1

pcm2: <Realtek ALC236 (Right Analog Headphones)> at nid 33 on hdaa1

Probably prevents switching kde5 or its pulseaudio.

Automatic sound switching does not work.

Did you try working through the stackexchange guide? Answer number 1 looks a good fit to your realtek audio chipset. Another thing to note, after you make entries in device.hints, you will see different output in dmesg than when there is no association defined. But I suggest have try at following the explanation in the stackexchange link.

The examples section of "man snd_hda" also has a detailed explanation of how the driver works. It's a real shame there isn't a way to auto-configure a sensible default so that the headphones / speakers switchover just works without the user having to figure this stuff out.

try switching it to seq=15 on headphones as I seen that once between my two systems where one showed seq=0 but when I changed it to 15 it worked, its a try not a fix unless that works.

Yes, I read carefully. That only I did not change, does not want to work!

but that's interesting when i turn off the second sound card hint.hdaa.0.disabled=1
then in manual mode

Code:

#sysctl hw.snd.default_unit=2

does not want to switch from headphones to speakers. When the card is turned on in manual mode, switching occurs. Paradox!
