I want to monitor the sound I am recording
 
I am running Fedora 9. I want to be able to record audio (I am using streamer to do so) but currently I cannot listen to what I am recording - I can listen after the event. Sometimes I check levels using Audacity.

I have been using the sound stuff on the motherboard - so I thought that perhaps that didn't like recording and playing symultaneously - so I put in a SoundBlaster card and tried that. I disabled the motherboard sound through the BIOS. At the moment, I can play audio files but I do not seem to be able to record anything.

If I open AlsaMixer, I get something that looks like two Volume sliders but with nothing to slide.

I have done a dmesg, a /sbin/lspci and also, from audacity, the Audio Device Information. Three are below.

Any help would be much appreciated.

By the way, I also have a Video Capture card which claims Audio input - but I do not use that.

dmesg output

You should be able to record (with playback / monitoring) in audacity (or ardour).

Audacity -> Edit -> Preferences -> Audio I/O -> Play other tracks while recording new one
and
Audacity -> Edit -> Preferences -> Audio I/O -> Software Playthrough: Play new tracks while recording it

With ardour you just need to setup the right connections in jackd. qjackctl or jack_connect

You might also be able to set that up in your alsamixer settings. For my Delta 44 there's a H/W and H/W 1 (+ 2 + 3), just change that from PCM Out to H/W In. Be careful though since a mic picking up output will cause feedback.

A lot of the integrated soundcards are NOT full-duplex. But they can record and playback at the same time, it's just that what's playing back will get partially captured on the recorded track. You need a full duplex soundcard to do multi-tracking. Not sure about playthrough, but you might need it there too. My laptop is particularly horrid in this regard. Desktops should be better, but not always.

I seem to have lost the ability to record.

I have reverted to the original hardware configuration - ie I have
removed the soundcard and re-enabled the onboard sound. I have reset the BIOS to indicate this.

Now, If I plug in a sound source (a radio) into the line-in and headphones into the output I can hear the radio through the headphones. However, I cannot record the radio.

If I start Sound Recorder, that gives me the opportunity to open Volume Control which gives me the chance to "Change Device". It lists 7 devices
0: HDA Intel (Alas mixer)
1: Brooktree Bt878 (Also mixer) --- This is my video card
2: Realtek ALC888 (OSS Mixer)
3: Playback: ALSA PCM on front:0(ALC888 Analog) via DMA (PulseAudio Mixer)
4: Capture: ALSA PCM on hw:1 (Bt87x Digital) via DMA (PulseAudio Mixer)
5: Capture Monitor Source of ALSA PCM on front:0(ALC888 Analog) via DMA (PulseAudio Mixer)
6: Capture: ALSA PCM on front:0(ALC888 Analog) via DMA (PulseAudio Mixer)

With the default (0) selected, I can slide the 'line' volume up and down - and that makes a difference in my headphones. However, if I try and record - either with streamer or with Audacity I get nothing (or so it would seem). If I try to record with Sound Recorder - it hangs.

Where should I look to find out how to get recording back?
