Did you choose right input (line/mic/master) for recoding?

I tried krec on my Fedora Core 6 desktop machine and I was also unable to get krec to work.

I tried audacity which is a Free, Cross-Platform Sound Editor and I was able to record a clip. You can check if your Mic is working by attempting to use this program instead.

yum install audacity

i tried even that...nothing got recorded... and when i tried the play button
i got this message:

Error while opening sound device. Please check the output device settings and the project sample rate.

Maybe your Mic can only handle a certain sample rate. Try switching the sample rates:

In Audacity click Edit->Preferences. Choose the 'Quality' tab and set the sample rate to 11025 Hz. If that doesn't work then try other rates.

well i tried that...still didnt work...the playback device couldnt be located...i get no options on the audio playback in the preferences....

Well at least we are homing in on the problem. In my Audacity preferences I have the following options.
Audio I/O Playback Device: OSS: /dev/dsp
Audio I/O Recording Device: OSS: /dev/dsp
Audio I/O Recording Channels: 2 (Stereo)

Something must be wrong with the sound card.
Try opening a terminal and run system-config-soundcard
enter root pw
Run the sound test.

If that does not work, try clicking system tab and click 'reload audio drivers', you will have to restart then try again. If that does not work, we will have to try messing with the sound card settings.

I tried system-config-soundcard, initially the sound card did test did not work, reloaded the audio drivers and rebooted the system. Now the audacity plays, well does not record yet.

I did a google search for "fc6 microphone test" and thought this solution might help you:


If that does not work:

Try running in a terminal gnome-volume-control.
Make sure the line-in bar is moved up.
Click Edit and Preferences and make sure "Microphone" is selected. Make sure Microphone's volume level is pulled up half way.
Try choosing the 'switches' tab and check or un-check the "line-in capture" check box and the Headphone Jack Sense checkbox.
