alsa sound + fc5: technically stupid but trying


Hi

After installing FC5 on a toughbook (Panasonic/matshushita) cf-50 the sound was working, no problem hearing even when running streaming media. However, the mic didn't work (wanted to try skype on linux :P )...so I read a bit online. However, I got burned fooling around with the alsamixer (is clear as mud to me): playing around trying to get the mic to work I have somehow turned off any sound.

Note: I have now also tried to change settings using gnome-volume-control and kmix. Nada, and a most confusing part (other than trying to figure out the alsamixer panel), is that none of these panels/guis seems to affect the other...

I really hope/think this is something stupid -- I am really blind here...

Below is what I can think of that might be a start, please advise on what else might be helpful to diagnose (and if at any time you can determine what is wrong, if you wouldn't mind, please send Detailed info on how to change the settings: I am all thumbs and no brain on this).

Thanks in advance

factoids:
(kernel) 2.6.17-1.2174_FC5

(alsa ver) alsa-lib-1.0.11-4.rc2

(sound card)

I dun know if the following will tell anything about the Alsa settings (I really need a tutorial to run that blankety-blank thang), but, just in case,

if you go to alsamixer If there are MM in any of the boxes just hit m at that box to unmute it, volume leves should be reasonably high. Just hit ESC to quit and save

this is unbearably stupid of me I know, but so far have found only the arrow keys and the tab key to move the cursor around. What is key combination to turn mic on (indeed there is an MM in its box). (For example I just now tried to use the Ins (insert) key and managed to add a L and R capture to the CD column...moving it off the mic column -- arghhhhhhhhhhhh!

What I (and mebbe others?) need is a blow by blow of the ALSA panel -- can find one nowhere, even on the alsa.org site...gad...(how can I be so Dumb!!!!!)

any help would be appreciated.

Thanks in advance

so i found out the >m< key mutes and unmutes (and now the mic is unmuted), but I still have no sound...speakers are unmuted...everything is now unmuted for that matter (even line, which I read somewhere might interfere with sound); in addition, all the options levels are set to somewhere 63->73%, even PCM.

I don't know what 3D control is all about...or if sigmaTel should be muted (it was, i didn do that) -- isn't that the chipset?

Thanks for any words...

argh,

man alsamixer
From a terminal

Calling yourself blind, all thumbs, etc. is unattractive. Simply asking the question will get a response.

alsamixer panel troubles

To re-clarify

The situation is this: the sound was working on my system (FC5/alsa drivers

I mucked around trying to get the mic to record in krec. I changed settings in gnome-volume-control, kmix and alsamixer. I managed (somehow) to turn the sound >off<.

Thanks to Debiant and some online reading the mic might be working (krec still not recording anything but I can hear noises from the speaker when I plug the mic in :] )

Since the speakers aren't playing anything (else)/headphones don'tg work, etc., as they had been, dunno what else to change in alsamixer (loads of permutations there) -- is it possible to devine what to change given the (above) scenario (or please let me know what additional info might be needed if this is possible). (Or, if the settings in the alsamixer are as individual as the online postings seem to indicate, is >how to get the sound back on< a needle in a haystack question to ask?)


Typically something like this might mean that something simple/basic is missing/mis-set, yes?

Did changing kmix and gnome-volume-control as well as aslamixer complicate the situation?

Though the situation is obviously difficult to assess (both for me and for someone trying to help), what info does one need to know in this situation in order to learn what to change? Put another way: does anyone know what to change or what they might need to know in order to help me understand what I need to change?

Thanks for any info/input.
