--00000000000020f0b805d30d51b1 Content-Type: text/plain; charset="UTF-8" I have installed FreeBSD 13 on my Optiplex 7080 mini tower, with KDE/Plasma desktop. Sound output works fine through the internal speaker, headphone and HDMI. I am able to switch these outputs with the plasma pulse audio volume controller. Connecting a headphone to the front audio port switches output from internal speaker to headphones automatically, as expected. However, I am yet to get a mic working on this machine, in FreeBSD. Headphone mic used to work fine with ubuntu that came preinstalled with this machine, hence, I believe that the hardware is alright. I have listed the outputs of some commands that I have come across from the Handbook and the forums, while I was researching for a solution. % cat /dev/sndstat Installed devices: pcm0: <Realtek ALC256 (Analog 2.0+HP)> (play) default pcm1: <Realtek ALC256 (Rear Analog Line-out)> (play) pcm2: <Intel Kaby Lake (HDMI/DP 8ch)> (play) No devices installed from userspace. % dmesg | grep hda* hdac0: <Intel Comet Lake-H HDA Controller> mem 0x91330000-0x91333fff,0x91000000-0x910fffff at device 31.3 on pci0 hdacc0: <Realtek ALC256 HDA CODEC> at cad 0 on hdac0 hdaa0: <Realtek ALC256 Audio Function Group> at nid 1 on hdacc0 pcm0: <Realtek ALC256 (Analog 2.0+HP)> at nid 20,33 on hdaa0 pcm1: <Realtek ALC256 (Rear Analog Line-out)> at nid 27 on hdaa0 hdacc1: <Intel Kaby Lake HDA CODEC> at cad 2 on hdac0 hdaa1: <Intel Kaby Lake Audio Function Group> at nid 1 on hdacc1 pcm2: <Intel Kaby Lake (HDMI/DP 8ch)> at nid 3 on hdaa1 The internal speaker and headphone work through pcm0. The front audio port uses a 4-pin jack, for headphone and mic. Could anyone please help me to get the mic working? Please advise me on what additional information is required to investigate the issue. Thanks in advance. --00000000000020f0b805d30d51b1--
