The internal microphone is listed by the Sound tool of Linux Mint Cinnamon but I cannot use it in any way.
I hope I have more luck here.
~ $ cat /proc/asound/cards 0 [PCH ]: HDA-Intel - HDA Intel PCH HDA Intel PCH at 0x81410000 irq 315
in response to dirkt's comment:
There is a MM to the right but not under PCM (isn't that the mic?).
amixer -c0 contentsgives this (pastebin)
I have tried to use with Skype and then tested with the 'Sound Recorder' tool, which only creates empty files. - Also I have tried
aplay /tmp/test-mic.wav(like here) to no effect.
in response to dirkt's second comment:
- the output of
cat /proc/asound/card*/codec\#*- here.The laptop only has one audio jack (entry), for headphones, I do not have an external mic to test if that could work for mic too.
