KDE won't make any noise
Last modified: 2007-04-18 12:30:57 EDT
I can't get any beeps under KDE. I'm trying 'echo -ne \\7' in a konsole (I also tried an xterm). I tried fiddling with as many sound configurations as I could find. I couldn't get either a normal beep (which is what I'm after) or a fancy wav.
Works here... Make sure the soundcard isn't in use by any applications that aren't using arts. One of the features of arts is that it can shut down while it isn't used to allow legacy applications to use sound, so if you run esd or something else using non-arts sound, KDE sounds will shut up until the application has exited. (Yes, KDE uses arts to produce \\7 beeps).
I think probably arts had crashed; I saw some messages like that in .xsession-errors. I'm afraid I don't have that now. It works for me too now. I'll see it I can get it to happen again.
Luckily, I've found the core file from artsd. Here's the backtrace. Shall I send you the core?

This defect is considered MUST-FIX for Florence Gold release
Just had this again, on a different machine.
Created attachment 8644 [details] output of 'gdb artsd core'
There have been a couple of major changes in arts in CVS recently... Please try the packages from http://www.linux-easy.com/daily/
I get lots of failed dependencies (libkdefakes.so.0), so I can't test them.
Try today's build from 7.1 (currently building). (I still can't reproduce this).
This might be a separate problem, but on this machine with no sound card, artsd won't start and so the PC speaker doesn't even work.
artsd also desn't work on a VAIO laptop with ymfpci sound driver in the kernel. Seems like artsd abort()s if a write() of sound data to the kernel is getting a short write. This does happen with the 2.4-0.1.12 kernel and its ymfpci driver. Why is this extra check in the artsd startup code?
Please check if this still happens with the current version, I could never reproduce this on my hardware.
The current KDE documentation has a comment saying that some Yamaha chipsets will work only at a sampling rate of 48000 Hz. Does the problem disappear if you go to KControl->Sound->Sound Server->Sound I/O, check the "Use custom sampling rate" button and enter 48000?
Closing due to lack of feedback
