[Alsa-user] Recording not working on Lenovo ThinkPad E540 (Audio device: Intel Corporation Atom Processor Z36xxx/Z37xxx Series High Definition Audio Controller)

[Alex A. <ale...@hy...>]

Hello all,

I'm trying to help a colleague that have Lenovo ThinkPad E540 to be able 
to record sound from his sound card Debian 8 "Jessie" with Linux Kernel 
4.9.

I'm a newbie in sound configuration so I don't know which information I 
should give you.

The output of "cat /proc/asound/cards" is :
>  0 [PCH            ]: HDA-Intel - HDA Intel PCH
>                       HDA Intel PCH at 0xd0810000 irq 107


When I use arecord I can hear my voice but when I'm trying for example 
from Mumble I can't hear my voice. When I'm trying Alsa from PulseAudio 
it doesn't work at all.

What can I do?

Best regards.
