First, reference your mic, the problem could be due to your having two sound cards. It could also be due to other reasons One negative aspect to Linux offering so much choice to the user, means sometimes things are hard to get working (as the default choice does not guess the correct configuration).
First, is this an INTERNAL mic or an EXTERNAL mic ? I assume an EXTERNALbecause you talk about 2 sound cards) but I am not sure. On what sound card did you plug in the jack on the PC ? In fact, what can you tell us about the sound card (s) ?
I do NOT use Skype, so if this problem has ANYTHING to do with Skype then I can not help you.
Note when testing your mic, I recommend you use a terminal with this command:
arecord -vv -fdat foo.wav
“foo.wav” is an arbitrary name I made up. Instead you could call it mydell.wav or thewindblows.wav or anything …
Then assuming mic does not work, please provide the information recommended to be provided here:
- set up your mixer such that it is correct for your mic to record (best you can) and then with your PC connected to the internet, run the script below, and provide the website page/URL (of a summary webpage) that are created by running the diagnostic script:
Note you must select the SHARE/UPLOAD option.
If for some reason that does not give you a web site URL/address, then please run that diagnostic again with the no-upload option to create an alsa-info.txt file by:
and it will create /tmp/alsa-info.txt. Open alsa-info.txt with a text editor, copy it, and paste it into a paste bin site such as Pastebin.com - #1 paste tool since 2002! or pastebin - Type, paste, share. or New - Pastie and then after submitting/pasting it on one of those sites, the site will update and you can copy the website address/url from that site, and post here the URL. Just post the URL. Do not post the entire content of the diagnostic script here. Just the URL.
- in a terminal, or xterm, or konsole, type: rpm -qa ‘alsa’ #and post output here
- in a terminal, or xterm, or konsole, type: rpm -qa ‘pulse’ #and post output here
