when i increase the front right internal mic volume, it outputting the feedback or noisy sound on the computer when i test it using google hangout from my laptop. So my question is how to make the internal mic output audio quality crystal clear even when the volume is maximum? my laptop is lenovo g40-45 sid with amd a8 and amd sound card and the internal microphone is connexant and i’m using openSUSE 13.2 64 bit
Well, that really comes down to the laptop speaker and microphone placement, as to what levels you can get away with. (Feedback is inevitable if the closed-loop gain is too high.) Consider using headphones, or maybe an external microphone.
another problem when i use external microphone the sound volume output is too low even when i maximize the volume -_-
but when i use windows, the feedback didn’t exist even i maximize the volume
Is there a ‘Microphone Boost’ slider as well as a ‘Microphone’ slider that can be adjusted?
Just to help others advise further…
Which desktop environment are you using?
Do you have the PulseAudio Volume Control (pavucontrol) installed? If not, it’s worth installing and using IMO.
KDE 4 and i already installed pavucontrol. and also noted i maximized the internal volume on pavucontrol

Well, the computer has motors: hard disk and cpu fan. Both produce
vibrations and noise transmitted by the plastic. It is unavoidable. Some
machines solve this better than others. Mine (a compaq) is too bad, so I
use headphones, sometimes without connecting the earpieces. A set using
bluetooth can be very nice, no cables, you can move around the room.
It is possible to do active noise cancellation. My Parrot™ device (car
phone system) uses a pair of microphones that are pointed to my head:
using I don’t know what algorithms they can cancel the car noise quite
nicely. It is interesting that even the person besides the driver is
also “eliminated”
Some mobile phones use similar techniques. There is a microphone pointed
more or less to the mouth, but there is another on the back that picks
background noise. Knowing the spectrum of the voice helps. Once I wanted
to send a voice-message with only the tremendous noise of a sea storm:
the message was almost silent, the noise was canceled out.

another problem so i tested with external microphone on maximum volume on pavucontrol. it sounds perfectly including the volume and clarity on audacity. but when i tested it using google hangout, the sound is too low. any idea?
Knowing more about the specifics of your computer and its audio setup may help in providing insight into what is going on wrt the mic and background sound.
Please run the following diagnostic script in a konsole/xterm as a regular user with your PC connected to internet:
/usr/sbin/alsa-info.sh
and do not update if asked to update, and select the SHARE/UPLOAD option. Allow the script to run to completion, upon which (after the completion) it will in the konsole/xterm provide a web/url address where your PC’s audio configuration has been uploaded. Please copy the web/url address (just the address) and post it here. We can then look at it and see if it provides some possibilities to better tune your audio.

OK, some settings I note:
**Simple mixer control 'Capture',0**
Capabilities: cvolume cswitch
Capture channels: Front Left - Front Right
Limits: Capture 0 - 80
Front Left: Capture 80 [100%] [6.00dB] [on]
Front Right: Capture 80 [100%] [6.00dB] [on]
**Simple mixer control 'Auto-Mute Mode',0**
Capabilities: enum
Items: 'Disabled' 'Enabled'
Item0: 'Enabled'
**Simple mixer control 'Digital',0**
Capabilities: cvolume
Capture channels: Front Left - Front Right
Limits: Capture 0 - 120
Front Left: Capture 60 [50%] [0.00dB]
Front Right: Capture 60 [50%] [0.00dB]
**Simple mixer control 'Internal Mic Boost',0**
Capabilities: volume
Playback channels: Front Left - Front Right
Capture channels: Front Left - Front Right
Limits: 0 - 3
Front Left: 1 [33%] [12.00dB]
Front Right: 1 [33%] [12.00dB]
One idea I have is for you to back off the capture levels from 100% to a lower level. One can get noise/distortion if the capture is too high. Try 80% or 70%. At the same time, increase the internal mic boost from 33% to 66%. And that may mean you will need to then tune further the “Digital” mixer capture levels.
ok i’ll try that later. I’ll report back if the problem still exists.
Okay,i think the problem is in the capture settings. I already set that on alsamixer the problem solve for a while when i speak on hangout but it raises the capture volume automatically to 100% Do you know how to save the volume settings on alsamixer? Thanks

Some applications could try to set up the volume automatically. I don’t
know if this is the case.

I need some application that can set the volume manually not automatically.

What I mean is that hangout might do that. Skype does.
I’m not saying that you use an application to do that. What I say is
that some of those communication apps do it, without asking. You find out.

Typically alsamixer is an app that works across all desktops.
Well - my experience on a few different PCs with Skype is it does not set the capture to 100% which is what the OP has set. For example, on one of my PCs I use a webcam for Skype with the webcam’s internal mic. Here is its capture settings:
!!-------Mixer controls for card 2 [U0x46d0x821]
**Card hw:2 'U0x46d0x821'/'USB Device 0x46d:0x821 at usb-0000:00:14.0-10.4, high speed'**
Mixer name : 'USB Mixer'
Components : 'USB046d:0821'
Controls : 3
Simple ctrls : 1
**Simple mixer control 'Mic',0**
Capabilities: cvolume cvolume-joined cswitch cswitch-joined
Capture channels: Mono
Limits: Capture 0 - 52
Mono: **Capture 23 [44%]** -48.00dB] [on]
44% is far from 100%.
My suspicion, is given given we see 100% capture in the user’s setup, is this is NOT some app automatically setting 100%.

Well, I did not say, I think, that it sets the level to 100%, but that
it can do some automatic adjusting. If the logics decide that it is not
capturing sound, I suppose that it would start cranking the level up to
the top.
