Solved Sound/Recording configuration

Hello,
I've difficulties in sound card configurations so both sound output and recorder are working.
On my HP Laptop is FreeBSD 11.0 installed.
/boot/loader.conf contains snd_hda_load="YES"
The driver is properly loaded, hardware is detected.
Without any changes hw.snd.default_unit=0 sound output works well. But sound recording doesn't.
By setting hw.snd.default_unit=1 sound recording works and there is no sound.
Unfortunately all the changes in /boot/device.hints and reboots were unsuccessful.

Here some system information in hopes of help.

Sound can be challenging in FreeBSD. In FreeBSD 10.1, snd_hda is statically compiled into the kernel. I do not know if the 11.0 developers changed it back to a module but if it is in the 11.0 kernel you would have it statically and as a module. It would be easy to check by removing the entry in /boot/loader.conf and then checking your dmesg.

It may also help to post your laptop model and more of your dmesg. snd_hda is used by many different chip manufacturers and it may be that someone has sorted this out on your model or a similar HP laptop.

Do your headphones work and do they mute the onboard speakers? Do you have a system bell(beep)?

It seems snd_hda is a part of kernel. snd_hda_load="YES" is removed from /boot/loader.conf and kldstat -v shows snd_hda.

Yes, but only if hw.snd.default_unit: 0 is.

No, but I haven't realized yet that my laptop never beeps.
 
Using snd_hda(4) and your pastebin output it appears that association 1 (as=1) is correct and pins 11 and 13 should be left alone.

Code: 
hdaa0: 11 0321101f   as=1    seq=15      Headphones         Jack  1/8     Left       Black   0
hdaa0: 13 90170110   as=1    seq=0       Speaker            Fixed Analog  Internal   Unknown

Association 2 shows two pin groups and two jacks: Left/Ext-Rear

Code: 
hdaa0: 12 03a11020  as=2    seq=0        Mic                 Jack 1/8           Left             Black   0
hdaa0: 15 2181102e  as=2    seq=14       Line-in             Jack 1/8           Ext-Rear         Black   0

If this is your physical configuration, can you record from Ext-Rear? It looks like you need to re-assign the gpio pins as described in snd_hda(4)

How can it be done? Are you mean by using suitable hint.hdaa.0.gpio_config setting?

There are fife GPIO pins on hdaa0 and consequently 120 possible mutations. Unfortunately I can't use kldunload(8)/kldload(8) and have to reboot for possibility. But my first fourteen attempts neither success nor change something. I'll report after the remains are done.

Maybe it could be helpful for another one:
Putting dev.hdac.0.pindump=1 into /etc/sysctl.conf seems to make snd_hda() more talkatively.

I looked up the HP EliteBook Folio 9470m on HP web site. The physical configuration is something I have not seen before. The audio out(headphone jack)/audio in (microphone jack) are physically the same. Page 21 in the manual I downloaded. The manual specifies that you must use a 4 conductor connector that supports both headphones and microphones. Older headphones were 3 conductor (right/left/common). There is also a built-in mic adjacent to the web camera. When you try to record are you using a 4 conductor jack into the left side of the machine or the built-in mic? Your mixer output shows you are recording from only one source.

Once you determine what your mic source will be (left jack vs built in mic) this would be how you would alter the configuration.

Edit: It also may help to compare the pindumps with default sound unit = 0 and default sound unit = 1

I really appreciate for your time and effort.

I've tried both of them. But only if hw.snd.default_unit=1 sound recording works properly.

It's definitely build in mic. In this case hw.snd.default_unit=1

Mixer ogain    is currently set to 100:100
Mixer monitor  is currently set to 100:100
Recording source: monitor

It also may help to compare the pindumps with default sound unit = 0 and default sound unit = 1
Click to expand...
The only difference I could see is hdaa0: GPIO0: input state=0 in hw.snd.default_unit=0 because hint.hdaa.0.gpio_config entry in /boot/device.hints, which was removed before
hw.snd.default_unit=1 boot
 
It looks like the recording source is "mic" when using "hw.snd.default_unit=0". With "hw.snd.default_unit=1" the recording source is "monitor" and that with the default snd unit at 1 you are able to record with the monitor's built in mic.

If you look at the pindump with the default snd unit=1, I would wonder if pin 15 is "monitor" with an as=2 and seq=0?
I would try swapping out the seq values for pins 12 and 15 with default snd unit=0. I would also play with the seq setting for nid12. If seq=15, it is supposed to mix the sound from the two sources, while seq=14 is to multiplex the sources.

/boot/device.hints
Code: 
hint.hdac.0.cad0.nid12.config="as=2 seq=14 device=mic"
hint.hdac.0.cad0.nid15.config="as=2 seq=0 device=monitor"
 
Many thanks for your help.

Now sound recording works properly without hw.snd.default_unit switching.
