[900X3G, Realtek ALC282, Mic, Internal] inverted mic not working

[aerobat]

Internal Mic of Samsung Ativ book 9 (NP900X3G) is not supported properly.

Stereo recording in audacity records sound from mic in L channel and only loud noise in R channel (phase inverted?)
Muting R channel, and setting L channel to around 16%, in pavucontrol allows to record audio, but in poor quality.

node 0x11 and node 0x08

Converter: stream=0, channel=0

stream of one audio input node should be non zero when recording while the other is zero

[Raymond (superquad-vortex2)]

if your internal Mic is inverted, the mute of right channel should be applied to node 0x11 instead of node 0x08

[Steffen Röcker (sroecker)]

Thanks Raymond. How can we try this? alsamixer is not very helpful as you do not see the node numbers. Do you know the commands for hda-verb?

[Steffen (fragone)]

This bug also affects me and I realized today that the internal mic starts working perfectly when plugging a smartphone headset and the headset mic does not work at all. So the modes might simply be switched somehow. Is there any possibility to configure it in a way so that it is set to the internal mic by default.

Problem still exists in trusty with mainline kernel 3.18.1-031801-generic.

performed a fresh install of ubuntu 15.04, still not working.

[hajtipajti (hajtipajti)]

Hello,

I have a Samsung 740U (from Series 7) and in the internal mic there is a constant noise.

[hajtipajti (hajtipajti)]

And I have Ubuntu 15.04

[annunaki2k2 (russell-knighton)]

Has anyone managed to come up with a solution yet?

[weesnich (weesnich)]

For me neither the internal nor a plugged in microphone work (besides USB ones). When I plug in a headset it activates my internal microphone but in horrible quality so that you can mainly only hear the fan rotating. But this seems to be an issue with pulseaudio as the plugged in microphone works well when I check alsamixer. anybody knows a fix?

[cgampert (cgampert)]

Referring to comment #24, using hda-analyzer, I could see that:
- Converter audio stream is set to 1 on node 0x11 when the Mic jack is unplugged
- Converter audio stream is set to 1 on node 0x08 when the Mic jack is plugged in

Having the mic jack plugged-in, it seems to reduce noise but it's still the internal mic which capture sound.

Referring to comment #25, using hda-analyser, I tried to mute right channel of node 0x11 but I couldn't see any difference...
