[TMP645-M, Realtek ALC282, Pink Mic, Left] No sound at all

[Steffen Neumann]

Hi,

I have an issue using the headset microphone.
hdajacksensetest will happily report the insertion and presence
of the headset (with two separate 3.5mm for input and output):
Pin 0x18 (Pink Mic, Left side): present = Yes

If I use alsamixer to increase the levels, and enable the "loopback",
I can hear the input in the headphones, but no levels are visible
running "SoundRecorder".

Happy to test whatever can help here. System is
an Acer TravelMate P645-M V4DA2 running 16.04
current as of 2nd of April.

Yours, Steffen

Seem node 0x18 is your mic jack. Index=1

control.14 { iface MIXER name 'Capture Source' value Mic comment { access 'read write' type ENUMERATED count 1 item.0 'Internal Mic' item.1 Mic item.2 'Mic 1' item.3 Line } }

You need to select mic 1

Hi Raymond, thanks for that blazingly fast answer. I created a file /etc/asound.conf
with the content for contro.l23/25/26/14 you posted above, was that the right thing to do ?
This solved my other problem with automagically switching to headphones
when they are inserted, that's great! I can now also use alsamixer to get
good quality from the headset microphone!

Will every user have to do this, or can these Acer P645-M specific settings
in asound.conf go into the appropriate ubuntu package ? Yours, Steffen
