Anyone get Acer laptop internal microphone working in Gentoo?
 

I guest you may need to play around with the mixer (KDE,GNOME) or
alsamixer to enable internal microphone. I have to enable
recording/capture in GNOME volume applet to make the internal microphone
worked on my D630.

Hope this help,
Hung

did you add alsasound to the boot process?




i went 6 months trying to figure out what was wrong with my microphone until i realised that i forgot to do that!




also unmute the microphones using alsamixer (in alsa-utils) like Hung sugested.

I had already unmuted everything before posting my question. With
enough microphone boost, I have a hissing noise. I didn't know about
alsasound being a daemon until today. With alsasound running, mencoder
and ffmpeg and arecord now *THINK* that they are recording a sound
channel. That's an "improvement", because they used to say "noaudio"
before. But still nothing gets recorded. Here is a sample command I
tried.

arecord -f cd -t wav -c 2 -D plughw:0 foobar.wav

Maybe I should go and buy an external microphone already.

I do not have your hardware, but on my laptop I could not get the microphone
to work until I switched on the digital capture and selected "Digital" under
Input Source in alsamixer. For some reason it would not work with any other
setting.

Perhaps because there is no analogue audio capture on my machine ... ?

$ cat /proc/asound/devices
2: : timer
3: [ 0- 0]: digital audio playback
4: [ 0- 0]: digital audio capture
5: [ 0- 0]: hardware dependent
6: [ 0] : control
7: [ 1- 3]: digital audio playback
8: [ 1- 0]: hardware dependent
9: [ 1] : control
10: : sequencer

HTH.

My system is very similar...

[aa1][root][~] cat /proc/asound/devices
2: : timer
3: : sequencer
4: [ 0- 0]: digital audio playback
5: [ 0- 0]: digital audio capture
6: [ 0- 0]: hardware dependent
7: [ 0] : control
8: [ 1- 3]: digital audio playback

What exactly do you mean by "switched on the digital capture"? In
alsamixer I have all sound capture settings on...

Front Mic Boost 67
Mic Boost 67
Capture 81
Capture 1 81
Digital 83

Ah ... mine have more. <F4> in alsamixer brings up all these Capture devices:

Front Mic 67<>67
Mic 67<>67
Capture 80<>80
Capture 80<>80
Digital 61<>61
Digital 33<>33
Input So Digital Mic (other options are: Front Mic, Mic)
Input So Digital Mic (other options are: Front Mic, Mic)

There's a microphone on the top of the screen and a jack on the front left of
the keyboard.

Another search on Goggle finally found something, but I'm not sure I
like it. My card shows up in "lspci -v" as...

00:14.2 Audio device: ATI Technologies Inc SBx00 Azalia (Intel HDA) (rev 40)
Subsystem: Acer Incorporated [ALI] Device 0372
Flags: bus master, slow devsel, latency 64, IRQ 16
Memory at d0400000 (64-bit, non-prefetchable) [size=16K]
Capabilities: [50] Power Management version 2
Kernel driver in use: HDA Intel

alsamixer shows...
Card: HDA ATI SB
Chip: Realtek ALC272X

One solution I've seen involves modprobing the sound driver with a
parameter. Problem is I've been using kernel-mode alsa for years and
I'm an absolute newbie on "alsa-driver". alsa-driver is keyworded
~amd64 but I'm desparate enough to try it. Maybe even desparate enough
to try the other solution, namely revert to OSS.

If I want to keyword alsa-driver and install it, I assume that I have
to remove all kernel support for sound, i.e in "make menuconfig"...

< > Sound card support --->

Is that correct? Also, what should I specify in ALSA_CARDS in
/etc/make.conf ?

I don't think so. One of my machines is a mac mini with the
intel HDA chipset, and I don't recall right now whether it
was alsa-driver, alsa-firnmware, or both but I did get it
working without disabling audio in the kernel.

ALSA_CARDS="hda-intel"
