I had a problem with Ogle (my DVD player) and it turned out to be a problem with the sound driver I'm using. I found this email in an archive that lead me to the workaround: <email> Wed Mar 24 2004, John Polstra wrote: > On 24-Mar-2004 Bj|rn Englund wrote: > > > Try setting the environment variable OGLE_OSS_RESET_BUG and then run > > ogle and see if you still have the problem or if it works. > > Wow, that fixes it!

But this is a common problem that pops up from time to time in different audio drivers, nothing chip/hw specific. I suspect that driver writers forget that the device should "reset"/be able to accept new format settings after a SNDCTL_DSP_SYNC or SNDCTL_DSP_RESET ioctl, and not just after a new open of the audio device. /Bj|rn </email> Should I do anything like file a bug report? I don't know what these guys have done. btw on my system `uname -a` says FreeBSD hercules.codepad.net 5.3-RELEASE-p2 FreeBSD 5.3-RELEASE-p2 #3: Mon Dec 20 17:20:40 GMT 2004 root@hercules.codepad.net:/usr/obj/usr/src/sys/HERCULES i386 -- /Xian "The important thing is not to stop questioning.
