Sounds kinda like when you had dust collected on the needle of your record player back when we were still using them. I've not been able to reproduce this consistently (i.e. it chokes at a certain time in one sound file, after a reboot that same file will play fine.) Here's my info: [larse@hbo: ~] cat /dev/sndstat FreeBSD Audio Driver (newpcm) Nov 10 2000 12:59:49 Installed devices: pcm0: <CS461x PCM Audio> at irq 5 (1p/1r channels duplex) [larse@hbo: ~] uname -a FreeBSD hbo.isi.edu 4.2-BETA FreeBSD 4.2-BETA #68: Fri Nov 10 13:00:17 PST 2000 larse@hbo.isi.edu:/usr/src-idprio/sys/compile/IDPRIO i386 Sorry I can't be more specific; if I had to guess I'd say some internal newpcm struct gets bashed by a rare pointer error... >How-To-Repeat: >Fix: >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
