I doubt it's a pulseaudio issue. What is the output of "arecord -l"? Are you sure that microphone is not muted or something? The only safe way to check that is to run alsamixer in the terminal, press F6 to choose the soundcard, select the actual hardware soundcard in the pop-up menu instead of the "default" (which represents the pulseaudio mixer), press F4 to see capture devices, and play around with the settings --- unmute everything, boost mic gain, etc. Then press ESC to exit alsamixer and try again with your favorite app. Open the app, begin recording, open pavucontrol, go to "recording" and "input devices" tabs, and boost the capture volume if needed. Also check there that everything is unmuted. If that doesn't do it, it's an ALSA problem with the driver for your card. Google is your friend. I don't see any other place where a mic could fail. Also, if you are unsure of the proper config of your recording app (they often can be misconfigured by default, skype being the typical example), use arecord --- that should always work if your driver is ok. Read the "man arecord" for examples on how to use it. > I checked to see what I can do about pulseaudio, and I see that these > are all the pulseaudio and related packages and just a short chain > of dependencies (I dod not do an exhastive dependency search, but > you will see that it is impossible to remove some of the packages > without killing your system Regardless of dependencies, I would say that it is a Bad Idea (tm) to remove pulseaudio. It is in the system for a reason, and it does its job well. PA is often used as a scapegoat when people run into sound problems, typically without it being the real culprit. Some time ago there was a witch-hunt against PA on this very list. It took a lot of persuading/teaching to help people realize that PA typically had nothing to do with their audio problems. > Here is a short list of dependents on these packages: > > pulseaudio-gdm-hooks is required by > gdm-2.32.1-2.fc14.i686 This is cute! :-) I really wonder why would a login manager need PA.

How can you expect pavucontrol not to be a dependency on pulseaudio-libs? In general, 90% of the audio problems are either down to wrong mixer settings (things being muted) or driver problems (ALSA being unable to drive the hardware). For the latter, you want to check on the Internet how good is the ALSA support for your hardware. For the former, the only two mixers I trust are alsamixer and pavucontrol. Note that in alsamixer you want to choose your sound card explicitly (or use the -c option) to reach the ALSA-level hardware mixer (which is below the pulseaudio mixer). Once you have configured the levels there, the only thing you ever need to use is pavucontrol, to change the levels of various sources on-the-fly, at the PA level. Other mixers (from gnome, kde, etc.) *should* provide equivalent functionality (and typically this works well), but they are just GUI's wrapped around alsamixer and pavucontrol, so you gain nothing by using them (other than nice "visual desktop integration", ie. eye-candy). If you need to troubleshoot something, ignore them and use pavucontrol and alsamixer only.
