Can't open audio device /dev/audio after some time of working in 4.5 needs reboot to fix the Issue
Hi,
I am running 4.5/i386 stable. After working on it for some time the
audio does not give out sound.
mplayer shows the following output.
$ mplayer Carrie\ Underwood\ -\ Jesus\ Take\ The\ Wheel.mp3

the song keeps playing but no sound comes out.
If i reboot I can hear the audio for some time and then it dies of
when I start the song again.
Is there any way to fix sound without rebooting?
Thanks

When I killed all the skype process i started getting audio. Also I am running fvwm2. when I move around an xterm window the sound stops. Is it an acceptable behavior? Thanks Siju

You mean it crackles (short interruptions), or it pauses completely for a long period? Pausing is ``normal'', i mean that's how software was designed. While you move a the xterm window, xterm refreshing is blocked, so is any program trying to write text on the terminal. It blocks on writing. So, typically a program with a progress bar, will block while writing on the terminal, and may stop processing audio until the xterm is unblocked. So, all depends on the program running in the xterm. If it supports non-blocking i/o on the terminal it wont pause, else it will pause. IIRC mplayer, mpg321, ogg123 all block on the terminal. If the program can't be fixed, a simple solution is to remove the progress bar, or whatever is causing terminal writes. -- Alexandre

Actually the sound stops even if i move other xterms which are not running mplayer. --Siju
