Can Not Start Audacity, Ardour, Sweep, Etc.

ALSA lib pcm_dmix.c:1018:(snd_pcm_dmix_open) unable to open slave
Cannot lock down 82246176 byte memory area (Cannot allocate memory)

Can Anybody Help Me?

Thanks For Your Answer.

Please give us enough background information to go on. What distro of Linux? The three-section Audacity version number at Help > About Audacity?

Are you running JACK? See for information on JACK and Audacity.

For what application are those console messages appearing?

Do these search results help?

[The dmix message is fairly normal in Audacity and should not be a problem].
