Description Jon Nelson 2005-08-27 17:36:14 UTC

Not sure what other information I can give you.

What's weirder is that when I log in I get the 'welcome' sound but then nothing
else works.

I found this in .xsession-errors:

CrashHandler: can't stop running as realtime process (Operation not permitted)

and this is the backtrace:

Comment 1 Jon Nelson 2005-08-28 17:00:28 UTC

More information:

I started artsd with this:

/opt/kde3/bin/artsd -F 10 -S 4096 -a alsa -s 5 -m artsmessage -c drkonqi -l 3 -f

and test with this:

artsplay /usr/share/supertux/sounds/squish.wav

and artsd dies a SIGSEGV immediately.

If I bump up the debug level, I get:
artsd version is 1.4.2
gsl: using Unix98 pthreads directly for mutexes and conditions

Comment 2 Jon Nelson 2005-08-28 17:08:14 UTC

I installed kdelibs3-arts and re-ran the test:

I get a bunch of dialogs when artsd is started:

"""
Sound server warning message:

unix_connect: can't connect to server
(unix:/tmp/ksocket-jon/linux.site-.....)
"""

and the same thing with "(The previous message was repeated 4 times.)"

If I try to play a sound:

"""
loading extension from
'/opt/kde3/lib/libartsgslplayobject.la' failed: file not found
"""

and

"""
Sound server warning message:

MCOP ObjectManager: Could not load extension libartsgslplayobject.la
"""

and

"""
Sound server warning message:

MCOP ObjectManager: can't find
implementation for Arts::GSLPlayObject.
"""

Comment 3 Stephan Kulow 2005-08-28 18:14:38 UTC

there is a reason we bann artsd from our default KDE

Comment 4 Jon Nelson 2005-08-28 20:25:29 UTC

Mr. Kulow - I would gladly give up artsd if I could - however, it's the only way
I know how to make games like RTCW and Quake, both of which require a mmap'able
/dev/dsp, to work.  I could use esd (esound) but that's even less desirable. Is
there another solution? If artsd is not installed, how do KDE sounds get played?

Comment 5 Stephan Kulow 2005-08-28 21:40:53 UTC

use the aoss wrapper. KDE applications use alsa directly

Comment 6 Jon Nelson 2005-09-01 15:06:07 UTC

I got everything working.
aoss doesn't work for me (crashes), but I found another way to make the game
(RTCW) work.

However, if artsd crashes then it should either be fixed or made unavailable. :-(

Thanks for your help!

Comment 7 Dirk Mueller 2005-09-05 22:02:21 UTC

sorry, nobody got time to fix arts
