I run an HP x 360 under Ubuntu 20.0.4 LTS. It has an NVIDIA GEFORCE GTX card in it plus all the standard device interfaces.
When I try to use the built-in microphone it doesn't appear to detect it at all. I can edit the alsa configuration, but am only able to have one of the sound or the mike working at any given time. In addition it, or at least "Settings", fails to detect the NVIDIA card as a possible output source.
Changing the last three lines of /etc/modeprobe.d/alsa-base.conf (see below) will turn the mike off if I set value = 0, but leave the sound on the speakers. If I try to set the options in these lines so that both are forced on (option >0) both appear in settings but only the mike works (obviously both lines uncommented!)
Note also in the final line that despite the fact that:
cat /proc/asound/card*/codec* | grep Codec
gives
Codec: Realtek ALC285
Codec: Intel Kabylake HDMI
At: https://www.kernel.org/doc/html/latest/sound/hd-audio/models.html
Alc285 is only identified as generic Alc28x and a specific codec is not listed. The final line in the config file attempts to use the fix to sort any HP x360 specific issues, but makes little or no difference.
How do I get access to speakers and mike (built-in or USB) to work? Is it a kernel issue
