http://brainstorm.ubuntu.com/item/7050/ First I had AC97 chip built-in, then I bought a soundcard (Muse) and deativated the built-in chip.

But still need to shout in the microphone to be listened. It might be a configuration issue, adjusting/tweaking volumes and others in Alsamixer...

But I have to say that on Windows, once your sound card works (ie you use the right driver), your microphone just works.

I find it really painful, and had to give up for now, without success.

No, it is not my idea, and as I said it might be a configuration issue... but complex to fix. I bought my Muse soundcard only for that reason, but it was the same.

The problem behind this could be as you said "Mine was muted at 4 different places by default".

Why is it muted by default ? at 4 different places ? how can a simple user go through this without being frustated ?

This might be enhanced, don't you think so ? this is why I created this "idea" : makes microphone works (like speakers works) without doing anything special. With today popular apps like Skype (or Ekiga), that device is REQUIRED.

I guess it's possible that the Windows driver is over-amplifying, making the input sound louder than it really is (which usually means it'll be distorted.) If so, then it would be bad to make it louder by default, but I'd still like to see an option to over-amplify if you want to, so I can use a quiet mic. Currently all my sliders are set to the max, and it's still not loud enough.]]> Thu, 17 Apr 2008 01:19:44 +0000 I tested a lot of things, without results !]]> Sun, 27 Apr 2008 08:31:29 +0000 Mon, 19 May 2008 01:45:32 +0000 Sat, 13 Sep 2008 16:47:03 +0000
(lspci -n)
00:10.1 0403: 10de:026c (rev a2)

Ubuntu 8.04

System->Preferences->Sound - ESD is turned off, on Devices tab all selected to ALSA.

Sound Mixer applet: Playback tab: General, PCM, Mic, Mic Boost, Mono.

1. What's Mic Boost and Mono?

ok, if Mic of Mic Boost not muted, I hear my voice in headphones when I speak to microphone- it 100% connected and works.

Record tab make me confused: only "Capture". Ok, it is ON.
Switchers: Mic capture, Phone, Mono capture.
I select Mic capture.

Try to capture sound:

$ arecord -f cd testfile.wav

result is file with silent.


$ hexdump testfile.wav | less

What's AUX ? What's MONO? What's IEC958???

So, I try different combination but can't record sound with arecord and gnome-sound-recorder at all.
