Hi,

Here are the values (as on the older system):

# cat /dev/sndstat
Installed devices:
pcm0: <Intel Haswell (HDMI/DP 8ch)> (play)
pcm1: <Realtek ALC283 (Analog 2.0+HP/2.0)> (play/rec) default
No devices installed from userspace.

# ls -l /dev/mixer*
crw-rw-rw-  1 root  wheel  0x4b  9 dic.  10:52 /dev/mixer0
crw-rw-rw-  1 root  wheel  0x4e  9 dic.  10:52 /dev/mixer1

# mixer -f /dev/mixer0
Mixer vol      is currently set to 100:100
Mixer pcm      is currently set to 100:100

# mixer -f /dev/mixer1
Mixer vol      is currently set to 100:100
Mixer pcm      is currently set to 100:100
Mixer speaker  is currently set to 100:100
Mixer mic      is currently set to 100:100
Mixer mix      is currently set to 100:100
Mixer rec      is currently set to 100:100
Mixer igain    is currently set to 100:100
Mixer ogain    is currently set to 100:100
Mixer monitor  is currently set to 100:100
Recording source: mix

(I also tested the other rec devices: speaker, mic, mix, monitor).

And recording does not get any input:

$ rec -c 2 /tmp/out.wav

Input File     : 'default' (ossdsp)
Channels       : 2
Sample Rate    : 48000
Precision      : 16-bit
Sample Encoding: 16-bit Signed Integer PCM

In:0.00% 00:00:07.34 [00:00:00.00] Out:348k  [XXXXXX|XXXXXX]        Clip:0    ^C
Aborted.

Where I put the XXXXXX normally indicators are moving according the level
of the recorded noise. Nothing is there, only blanks.

Thanks
