I have the Zoiper softphone to make VoIP-calls to my Asterisk server.

But I notice that my mic of the logitech headset is not working properly.

There's a volume meter for the microphone, and it is not moving when I speak. Sound is no problem and I hear the other party clearly.

In the options-section of the Zoiper-IAXphone, I can select an audio-device for input and output.

With 'input', I have 2 options :

- HDA Intel: ALC888 Analog (hw:0,0)
- HDA Intel: ALC888 Analog (hw:0,2)

Volume control is made with the HDA Intel (Alsa mixer)... so that explains the 'HDA Intel' that is mentioned.

But what is this hw:0,0 and hw:0,2.

Neither of the 2 settings seem to make my microphone work...

I noticed this when I wanted to test my voicemail system and it stated that it had recorded 10 seconds of silence .

Playing music with an audioplayer like MPlayer works well... And I am receiving audio from my Asterisk IVR-system.

It's really just the damn mike !

I have a Logitech VOIP headset I bought for use with Asterisk and it also has problems with the mike - but it does work after a fashion. A cheapie headset I picked up on special works 100% though LOL!

I´m using the xten-xlite softphone with Fedora 10 with no hassles - you can get it here http://www.counterpath.com/

The thing is... I have yet made phone calls to my colleagues with this Zoiper softphone + Logitech headset, and I could talk to them, no problem.
But don't ask me what settings I used..

Now I'm trying every combination in my audio-settings...

I have two mikes with my Acer Aspire 5920... one built-in in the closing led (next to my built-in webcam) and one 3,5mm-jack for mike-entry.
No audio is coming through from both...

It worked before...

But can someone explain me how I can see that my hardware (the 3,5mm jack where I put my mike in) is working properly ?

Thanks for the response.

Maybe something usefull :

system > preferences > hardware > sound :

the testing that can be done there by pushing the 'test'-button, doesn't play a sound, I here nothing...

If there is something on Linux that I'm a noob in, it's sound and it's devices and its drivers (alsa and oss ??).
Don't know what I use..

EDIT : this is because I selected the output-device of my Zoiper-phone as the speakers...
When I select another output-device (those of my headphone), I do get a test-tone.
So... it's not the driver I guess.

OK, I´m ignoring the built in webcam mic as you are using the headset. Right click the speaker icon (top right toolbar), open volume controls and you will see something similar to the attachment.
Select device xxxx (ALSA mixer) and play with the mic settings.

The webcam mic will be under another entry in the device pulldown.

This how it looks :

You are missing a front mic slider, click on preferences and select it.

Check my settings :

Most peculiar - I just checked on a Ubuntu system with working softphone and a Intel HDA (Alsa mixer) and that also has Front Mic checked. Microphone, Mic Boost & Front Mic Boost are unchecked (same as the Fedora system). Why your system lacks these options I don´t know.

One thing I spotted is that the mic level control on the xten-xlite softphone I use does NOT affect the levels in volume controls - possibly yours are set low or muted?

the mic in the fedora settings is set to mute by default and "not shown" also by default

I did some reading and came across a old reference to pulseaudio interfering with /dev/dsp. Go to System monitor > Processes, if there is a entry for pulseaudio try stopping or ending it and see if that fixes things.
