Description Giovanni Venturi 2004-01-25 14:27:01 UTC
Version:           sconosciuto (using KDE 3.1.5)
Installed from:    compiled sources
Compiler:          gcc version 3.3.2
OS:          Linux (i686) release 2.4.24

Sometimes at KDE startup or when kaboodle play a song KDE say me:
"Sound server fatal error: cpu overload, aborting."
It's happening with KDE 3.1.5 qt 3.1.2 all compiled from CVS KDE_3_1_BRANCH and with alsa 1.0.1. I recompiled alsa and kdelibs again, but nothin.
(It happens also with KDE 3_2_BRANCH but when I installed alsa 1.0.1, I don't recompiled 3.2 branch.)

Created attachment 4378 [details]
Small test app for verification

Adding a test application to prove the ALSA detection I'm using in attachment
#4377 [details] actually works - compile with gcc -o alsatest alsatest.c -lasound and run
it w/ different sound systems loaded for a quick test of the checking code.

I didn't understand but this bug is closed or not because I didn't see your 
patch into arts module on CVS. And it happens also with alsa 1.0.2 of the 
kernel 2.6.3. On recently KDE 3.2 BRANCH.

Comment 8 Giovanni Venturi 2004-02-19 01:29:35 UTC
I removed autodetect and I set ALSA directly and now it works. The bug can be 
closed. Thank you.

Comment 9 Arnold Krille 2004-02-20 17:53:36 UTC
Autodetection of alsa should be fixed. In the meantime set the output to alsa directly, not autodetect...

Comment 10 Luc de Louw 2004-03-14 21:40:48 UTC
Seems not to fixed yet, at least not in the current HEAD.
I'm using alsa 1.0.3, Kernel 2.6.4, KDE HEAD as of 2004-03-14

Comment 11 Jannick Kuhr 2004-08-28 22:54:40 UTC
I still get "Sound server fatal error: cpu overload, aborting." using arts with Gentoo on AMD64, KDE 3.3.0 and even if I select alsa manually.

In addition the system freezes, if I check "realtime priority" and play some sound.

I'm using alsa-drivers of kernel 2.6.7 (emu10k1 & via82xx)

Comment 12 Allan Sandfeld 2004-08-28 23:03:37 UTC
That is likely a different issue. Please report the output of starting artsd with debug ("artsd -l0"). And open a new bug-report if the ALSA-driver is loaded.
