Looks like IRQ handling/buffering problem, but in the same time 8000/12000/16000/24000/32000/48000 samples playing quite well. Bug remains the same since 4.6-RELEASE, 4.5-RELEASE/STABLE worked perfectly. >How-To-Repeat: Take a wave file, e.g. 11025Hz/mono and try to play it. Could be easily reproduced using "play" script from SoX port. >Fix: The only 100% workaround is to put sound sources from 4.5-RELEASE into source tree and rebuild kernel. Need some modifications of Makefile - removal non-existent (in 4.5) sound drivers. >Release-Note: >Audit-Trail: >Unformatted: >System: FreeBSD neuromancer.solaris.ru 4.7-PRERELEASE FreeBSD 4.7-PRERELEASE #0: Tue Sep 10 16:26:29 MSD 2002 root@neuromancer.solaris.ru:/usr/src/sys/compile/NEUROMANCER i386 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
