I am attaching the dmesg output and my kernel config file if that would be helpful. as you can see, pcm shows: pcm0: hwptr went backwards 3896 -> 3720 with PRE_SMPNG it didn't show such things, and when I do not load the machi= ne with compiles, it never displays such messages and plays fine. any info will be greatly appreciated. -tacho -- [i don't follow] | [http://daemonz.org/ || tacho@daemonz.org] [everything should be made as simple as possible, but no simpler] 0x44FC3339 || [02B5 798B 4BD1 97FB F8DB 72E4 DCA4 BE03 44FC 3339] --RnlQjJ0d97Da+TV1 Content-Type: text/plain; charset=us-ascii Content-Disposition: attachment; filename=THING Content-Transfer-Encoding: quoted-printable # # GENERIC -- Generic kernel configuration file for FreeBSD/i386 # # For more information on this file, please read the handbook section on # Kernel Configuration Files: # # http://www.FreeBSD.org/handbook/kernelconfig-config.html # # The handbook is also available locally in /usr/share/doc/handbook # if you've installed the doc distribution, otherwise always see the # FreeBSD World Wide Web server (http://www.FreeBSD.org/) for the # latest information. # # An exhaustive list of options and more detailed explanations of the # device lines is also present in the NOTES configuration file.
