From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.2.1) Gecko/20030225 Description of problem: The symptoms of the problem are very similar to the ones of bug 73334, but apperently they are unrelated, so I'm opening up mu own bug... I've created this little test prgram I'm attaching here. When I run this, it seems to writes some 4kB. to /dev/dsp and then hangs while the first second or so of the sound keeps looping. It seems however that there is some timing issue involved as well. If I decrease the buffer size, sometimes the entire files can play (though the sound is terribly broken up) An excerpt from lspci -vvv 00:0d.0 Multimedia audio controller: Creative Labs SB Live!

Version-Release number of selected component (if applicable): kernel-smp-2.4.20-18.9 How reproducible: Always Steps to Reproduce: 1.compile and run the attached test program 2.listen to the noise Additional info:
Created attachment 92437 [details] test case
And the proble is still there in kernel-2.4.22-1.2115.nptl
Since this has always worked using ALSA drivers and since they are now incorporated into the 2.6 kernel, I'll just close this bug as RAWHIDE (is this still the correct status athough it's not called rawhide anymore?)
