[SOLVED]Internal mic

Hi, I can't get my internal mic to work! I've been looking around and all I can find is to make sure that I have capture on (alsa f4 spacebar) and that snd-hda-intel is a module and that it's loaded. I'm using x86_64

Code: Select all

00:1b.0 Audio device: Intel Corporation 5 Series/3400 Series Chipset High Definition Audio (rev 05)
	Subsystem: Lenovo Device 38af
	Flags: bus master, fast devsel, latency 0, IRQ 43
	Memory at d8400000 (64-bit, non-prefetchable) [size=16K]
	Capabilities: [50] Power Management version 2
	Capabilities: [60] MSI: Enable+ Count=1/1 Maskable- 64bit+
	Capabilities: [70] Express Root Complex Integrated Endpoint, MSI 00
	Capabilities: [100] Virtual Channel <?>
	Capabilities: [130] Root Complex Link <?>
	Kernel driver in use: HDA Intel
	Kernel modules: snd-hda-intel

Thanks for any help

Does this work:

Code: Select all

 arecord -D plughw:0,0 test.wav

?

Progressively turn up the volume and repeat a few times to make sure it's not just very quiet.

If it doesn't, please post the output of amixer.

What is your kernel version? There are some problems with this conexant chip. I am currently using 2.6.36. In this kernel, I had to blacklist the module snd_hda_codec_conexant (didn't want to recompile the kernel). Otherwise the internal mic won't work.

But with this module unloaded you will notice that the speakers are not muted when you insert a headphone. So, you have a choice: 1. use conexant module and lose internal mic. 2. don't use conexant module and lose speaker-mute-on-headphone-insert.

My current /etc/modprobe.d/alsa.conf is as follows:

Code: Select all

~> grep '^[a-z]' /etc/modprobe.d/alsa.conf 
alias /dev/mixer snd-mixer-oss
alias /dev/dsp snd-pcm-oss
alias /dev/midi snd-seq-oss
alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-hda-intel

I think the fix for this card is in 2.6.38, but i haven't upgraded to that kernel yet (waiting for tuxonice).

Black listing snd_hda_codec_conextant worked for me. Thanks so much

Just an update. This has indeed been fixed in 2.6.38,- now you can have the speakers muted when you insert your headphone and have the internal mic working.

In 2.6.38 you need to
1. remove the blacklist on conexant module, and allow it to load
2. add the following line to /etc/modprobe.d/alsa.conf

Code: Select all

options snd-hda-intel model=asus

I have tested with the internal mic. I am not sure if the external mic works, because now there is just one microphone shown in alsamixer.

hi,

my relevant output looks like this:

Code: Select all

alias snd-card-0 snd-hda-intel

alias /dev/dsp snd-pcm-oss
alias /dev/midi snd-seq-oss

Code: Select all

# arecord -L

surround71:CARD=Intel,DEV=0
    HDA Intel, ALC259 Analog
    7.1 Surround output to Front, Center, Side, Rear and Woofer speakers

does that mean that i have no mic at all? ( samsung 580 pro)
or am i missing some kernel stuff?

cheers!

Probably driver is not updated enough to detect and enable the mic.
