microphone volume is really low, can't turn it up.

I have a different Conexant chipset (Conexant CX20590) and my microphone is also unusable due to noise. (It sounds like a jet engine as well as me or it sounds like nothing - can't get just me with no jet engine effect.) For input, I get three columns in alsamixer: Capture; Analog Mic Boost; Digital.

I can not enable the +20 boost for my microphone using alsamixer in the 64 bit Beta 12.04. AlsaMixer identifies the device as NVidia CK804 and identifies the "Mic Boost" setting as on/off +20, but the up/down arrows do not change the setting. With the gain on the microphone set to the maximum, it is barely audible and effectively unusable.

Hello,

I have recently acquired a Lenovo SL510 notebook. I have installed Ubuntu Karmic, everything seems to work fine except the builtin microphone. Any assistance would be appreciated.

thanks!

Here's some info about the laptop:

laptop:~$ uname -a

I have a thinkpad t410 with a combo headset/mic jack (just one for both) but can not seem to get ubuntu to use my headset microphone.

The internal microphone works fine..in fact, when I plug in my headset the audio comes through the headset but the microphone is actually the internal mic not the ones from the headset.

I have checked my sound preferences and only have one option of device to choo

I have set my parents up with Ekiga on their Windows machine and we have successfully linked up via video (so they can see their grandchildren). I can hear my parents fine via their internal microphone but I am having problems with mine. I have read many google and forum posts about this bug.

HI! I installed Ubuntu 9.10 on my Acer Aspire 6530G. It has a ALC888 sound card. The loudspeakers work well, but the micorphone doesn't works. I tried to check if microphone was muted (alsamixer), I increased the microphone volume to the max value but nothing changed. Can anyone help me?

Sorry for my English, I'm Italian :(

Hi,I've a PLANTRONIC Gamecom microphone.

Hi! I'm having trouble with the microphone of an hp mini 3500. The thing is that I can't record anything. I've already set the "mic","capture","digital" and "internal mic" controls on alsamixer and the microphone doesn't seems to work :( Any help???P.D. I've already check that the hardware works, tested on a live ubuntu cd :S

I have a Gateway MX3210 laptop running Ubuntu 9.04 and the sound works, but the microphone jack doesn't. The problem isn't limited to Skype. I wanted to be sure that one of my settings are correct. I have the following checked in the Volume Control Preferences:
