Hello, I'm trying to get mic working with ALSA on Arch Linux. I have installed sof-firmware along with alsa. My alsa card is sof-hda-dsp. The chip is Realtek ALC287. I have following items in capture tab of alsamixer. 1. Mic Boost (I have set it to max) 2. Capture (maxed and toggled to on) 3. Dmic0 Front (maxed and toggled on) 4. Dmic0 Rear (maxed and toggled on) 5. Dmic1 2nd Front (muted and can't toggle) 6. Dmic1 2nd Rear (muted and can't toggle) 7. PGA2.0 2 Master (muted and can't toggle) Output of arecord -l: **** List of CAPTURE Hardware Devices **** card 0: sofhdadsp [sof-hda-dsp], device 0: HDA Analog (*) [] Subdevices: 1/1 Subdevice #0:
