hi
I don't have your device but lets start the ball rolling.
1) what are the usb ids?..run lsusb pls
2) are those jacks 3.5 mm?
3) so run alsamixer...tab to capture...(install alsa-utils to get these commands)
look at the picture in Sound in section pls

connect your mic to front mic and set input to front mic and set volume up and unmute....depending on mixer controls you use...I prefer you alsamixer.
If you have no front mic connector change to mic which = back mic and raise the volume for that setting.
Remember if you have multiple devices...you can then see section webcam mic...where you get a choice.....but that option may not work for you as you have ONLY 3.5 mm connnectors? or are there more?
In other words your cam is not cam...to alsamixer its merely a sound in or sound device.
So work out how to get sound in first then record something.
arecord -d5 -c 2 -r 16000 one
play it back with your preferred player.or aplay.
if sound in now works....then most problems with sound out are a lot easier to troubleshoot
If you prefer kmix see the bottom pix
good luck
