recording audio from a microphone
Has anyone recorded audio from a microphone using Linux? If so, how?
I just want to record my voice saying hello world and save it as an .wav or .mp3 file. I've tried using Knoppix 4.0.2 by starting Audacity (K > Multimedia > Audacity ) and then clicking on the red Record button, but all I get is a loud hum. Do I need to configure something else first, e.g. load a module, configure a device, something?
The machine is an eMachines T23341. lspci lists the sound card as "multimedia audio controller: VIA Technologies, In.c VT8233/A/8235/8237 AC97 Audio Controller (rev 50)." Been googling but haven't found anything helpful, yet. I've also been reading the Audacity tutorials.
BTW, if I boot the same machine with Windows XP, everything works just fine using Sound Recorder, but I can only record 75 seconds.

Sorry, I don't have any answers about your hardware or Linux. But re the above quote, sound recorder is a typical MS "good enough for our users" type of program. OK for a quick test of audio in, but that's about it. If you want a great open source audio recording and editing program for Windows XP (and 98, as well as for Linux and MacOsX) that will get you past the MS limitation, look at Audacity, availabe at the link provided and also as part of TheOpenCD.
By the way, Audacity is on the Knoppix DVD (but not the CD), so you may be able to get it working from Knoppix too.

Actually, Audacity is on the 4.0.2 CD, too. It's what I've been using. I just don't seem to be able to get it to record. Plays existing recordings just fine, though.

I just booted my 4.0.2 DVD (wanted to use the CD but it seems that although I've downloaded and seeded the CD version, I haven't actually burnt a copy yet). Will have to do that soon, but the system I burn with is tied up for a while. After boot I didn't do anything except start Audacity from the multimedia menu. Picked English as the language. Pressed the record button and talked into my microphone. It recorded the audio. Signal trace shows a nice strong level with no clipping. It doesn't sound that loud when played back, but it's certainly there and what I recorded. Maybe my playback volume needs increased. This is on an HP Ze4240 notebook with on-board audio.
