View Full Version : Audacity: "There was an error initializing the audio i/o layer.'

11th September 2006, 04:54 PM
Hello, I just installed Audacity on my Fedora Core 5 x86_64 machine using the command "yum install audacity" and the Livna repository. However, when I try to run Audacity, I get the following error message popping up.

"There was an error initializing the audio i/o layer.
You will not be able to play or record audio

Error: Host error."

Audacity then continues to open up, but I can't use it.
I searched this forum the Audacity forum for a cure and it seemed to suggest I was missing something called oss-alsa, so I tried "yum install oss-alsa" and varients thereof, but there was not match to oss-alsa, aoss, etc.
Can anyone please help me? My soundcard is a C-media and the Kinfocentre kicked out the following information for it:

set the audacity audio device to /dev/dsp and be sure to kill the sound server before strating audacity (artsd for kde; esd - not sure - for gnome).

I opened up the "Audio I/O" panel in the preferences menu, but there were no devices in either the input or output drop down menus. Is this what you meant?

yep. But first close audacity, kill the sound server and then re-open audacity.

Sorry, but could you give a bit more of a detailed description of how to "kill the sound server"? I'm using KDE.

open a terminal and type

killall artsd
and you're done.

I did that and there are still no devices in the preferences window.

Sorry, no other ideas. I'm using a CVS version compiled with portaudio v19 and it works fine.
Try reading this, I hope you will find something useful (I saw that you posted on the audacity wiki, so maybe you already know about this...).
