Ubuntu: Internal Microphone not capturing input



Question:

The Internal microphone on dell Precision 7510 is successfully detected on Ubuntu 16.04, however it does not capture any input.

From others thread I tried editing the alsa-base.conf file to include different models to no avail.

Using pavucontrol also was not successful.

aplay -l Output is as follows:    card 0: PCH [HDA Intel PCH], device 0: ALC3235 Analog [ALC3235 Analog]    Subdevices: 0/1    Subdevice #0: subdevice #0  card 0: PCH [HDA Intel PCH], device 3: HDMI 0 [HDMI 0]    Subdevices: 1/1    Subdevice #0: subdevice #0  card 0: PCH [HDA Intel PCH], device 7: HDMI 1 [HDMI 1]    Subdevices: 1/1    Subdevice #0: subdevice #0  card 0: PCH [HDA Intel PCH], device 8: HDMI 2 [HDMI 2]    Subdevices: 1/1    Subdevice #0: subdevice #0    while the content of /proc/asound/cards is:         0 [PCH            ]: HDA-Intel - HDA Intel PCH                            HDA Intel PCH at 0xdd348000 irq 130  

How can I resolve this problem?
