Continous buzzing sound in kde

Continous buzzing sound in kde

[Peter H.]

Hi,

In slackware 9.1 where I had to change from alsa to OSS sound system due to 
distorted sounds with alsa I still can not open kde desktop.

Trying to do so I get a continuous, annoying buzz, necessitating a quick 
ctrl-alt-backspace retreat.

This shows on the console:

AudioIO::close(): entering
AudioIOOSSThreaded::stopThread() entering
waiting for writerThread to finish
AudioIOOSSTHreaded::writerThread() fatal error writing to a audio_fd
AudioIOOSSThreaded::writerThread() thread stopped
AudioIOOSSTHreaded::readerThread() fatal error reading from audio_fd
AudioIOOSSThreaded::readerThread() thread stopped
waiting for readerThread to finish
AudioIOOSSThreaded::stopThread(): leaving
AudioIO::close(): leaving

Any suggestions to stop this buzzing sound?

There is no sound problem with gnome or fvwm2.

Regards

Without knowing the soundcard and computer specs how can one even start to 
help you Peter.

Having one of these chipsets i sympathise with you, however i dont have your 
problem.

So it seems the problem arises when kde is starting, this would point to the 
file (default sound file) KDE_Startup.wav found in /opt/kde/share/sounds/

The funtion audio_fd is another word for /dev/dsp (at least it is normally),
I would simply move or rename KDE_Startup.wav and see what happens.

The buzzing sound would possably interpret a missed interrupt or some 
interrupt sharing problem, if you use google.com/linux you may well see that 
others have reported simalar problems at some time or other.

Of course it could well be that the .wav may be corrupted in some way and 
kicks the problem off.

You could once again use strace to catch the problem, however be prepared if 
you do for one hell of a big strace file.

In the control center sound system in Sound I/O disable "Enable full duplex 
operation".

In the trace you sent me i found;

ioctl(3, SNDCTL_TMR_TIMEBASE, 0xbffff640) = -1 ENOTTY (Inappropriate ioctl for 
device)

Yes, i was about to write to you, the above is what i think is/was the 
problem, however it should not cause a buzzing sound, anyway glad it now 
works.
