hi, unfortunately I don't have these controls in mixerctl either, and
I've tried all the other numerical ones and they seem to have no effect.

the dmesg output is pretty ridiculous:

hdaudio0 at pci4 dev 0 function 1: HD Audio Controller
hdaudio0: interrupting at ioapic0 pin 17
hdafg0 at hdaudio0: vendor 10de product 0040
hdafg0: DP00 8ch: Digital Out [Jack]
hdafg0: DP01 8ch: Digital Out [Jack]
hdafg0: DP02 8ch: Digital Out [Jack]
hdafg0: DP03 8ch: Digital Out [Jack]
hdafg0: 8ch/0ch 48000Hz PCM16*
hdaudio1 at pci0 dev 27 function 0: HD Audio Controller
hdaudio1: interrupting at ioapic0 pin 22
hdafg1 at hdaudio1: vendor 1102 product 0011
hdafg1: DAC00 2ch: Speaker [Jack]
hdafg1: DIG01 2ch: SPDIF Out [Jack]
hdafg1: DAC02 2ch: HP Out [Jack]
hdafg1: ADC03 2ch: Line In [Jack]
hdafg1: ADC04 2ch: Mic In [Jack]
hdafg1: 2ch/2ch 48000Hz PCM16*
audio0 at hdafg1: full duplex, playback, capture, mmap, independent

I assume the first part is for my graphics card. I can't use it with
my headphones.

mixerctl -a looks as follows:

inputs.reclvl=0,0
inputs.reclvl2=0,0
inputs.line=0,0
record.mic=0,0
inputs.beep=248,248
inputs.beep.mute=off
outputs.dacsel=DAC00,DIG01,DAC02
record.source=ADC03,ADC04

It's very silly, I've got all these audio ports and only DAC00 works,
and I have to be careful not to reboot my machine instead of powering
off and starting again, because then audio will cease to work.

The same behaviour exists in Linux.

Thanks for the suggestion!
