View Full Version : Confused with sound in F9

I am getting more and more confused with the audio on my system - progesss all seems to be backwards.

I am running Fedora 9 on a machine with Realtek ALC883 on the motherboard. I want to be able to record audio through the Line-In (and monitor the input and edit the recording using headphones on the output). In addition to 'vanilla F9', I have installed ALSA Mixer.

From the Applications menu, Under Sound and Video, I can select the ALSA Mixer - which does not seem to allow me to control anything.

Using the PulseAudio Volume Control, I can adjust the input for the Front input - but I cannot see how to adjust the volume for the Rear input. The PulseAudio Volume Control does allow me to control the level of the recording - but only when I connect through the front inerface.

In messing about, I have lost the ability to listen to what is being played by audacity. I notice that I can go to Edit>Preferences and set the playback device to be one of
ALSA:HDA Intel: ALC883 Digital (hw 0,1)
ALSA: iec958
ALSA: spdif
I assume that it is the first that I want

I would appreciate any help a) recording through the rear connector and b) listening to what audacity is playing

TIA

"From the Applications menu, Under Sound and Video, I can select the ALSA Mixer - which does not seem to allow me to control anything."

The default mixer control is pulseaudio now so you have to select the hardware card. What I do is right click on the menu item for alsa mixer, then hit "add this launcher to desktop". Now look at your desktop for the new icon right click on it and hit properties, then hit the launcher tab. Edit the line that is labeled Command: to read:
alsamixergui -D hw:0

Thank Jeo. I can now see some sliders to play with.

That leaves the audacity question.

I can capture audio and I can see in audacity a 'healthy' waveform. If I export the track as a WAV file (for example) I can play it with Movie Player - and it plays (I can hear it). However, when I play it with audacity, I hear nothing. The 'VU Meter' shows that something is being played - but nothing makes it into my ears.

Would it help to uninstall audacity and install it again?
