Can you try this:

Not sure about the mic though - so my proposals will be a bit vague.
First, inspect the output of:
Code:
$ cat /proc/asound/cards
I'll assume you have alsa-utils installed: does recording with ALSA utilities - like arecord - work?
ALSA mixer is (alsamixer) also quite good in diagnosing - do you see the input in it, is it not muted, are the recording levels right?
Thanks,

Michal,
The cat command gives me the following result:
cat /proc/asound/cards
0 [PCH ]: HDA-Intel - HDA Intel PCH
HDA Intel PCH at 0x94320000 irq 131
1 [Dock ]: USB-Audio - ThinkPad Basic USB 3.0 Dock
DisplayLink ThinkPad Basic USB 3.0 Dock at usb-0000:00:14.0-2.3, super speed
I the used alsamixer and made sure that everything is un-muted.
In the alsa mixer I also see S/PDIF, S/PDIF 1 and S/PDIF 2.
I have als set the mic boost to the maximum.
I have tested with Ubuntu's (use both the analogue and digital inputs).
I also tested with:
arecord test.wav
The result is I can hear very faint noise when I strike the mic.
The voice is imperceptibly low. So the input seems to be working.
Its just being picked up correctly. I retested the cable with the laptop's jack.
No problem here.
Can anyone tell me if they were able to use the mic inn Linux?
TIA.
