The sound mostly works. I can play MP3s using mpg123/x11amp/xmms... The problem is that when I start moving the mouse around a lot, the sound distorts and the kernel occasionally spits out a message like: Mar 8 16:07:17 choplifter /boot/kernel/kernel: pcm1: hwptr went backwards 536 - > 444 Here's the uname output and contents of /dev/sndstat (the sound card is built-in to the motherboard, one of the CS423x chips): FreeBSD choplifter.telerama.com 5.0-20010126-CURRENT FreeBSD 5.0-20010126-CURRENT #1: Mon Feb 12 17:40:59 EST 2001 ncrawler@choplifter.telerama.com:/usr/src/sys/compile/CHOPLIFTER i386 % cat /dev/sndstat FreeBSD Audio Driver (newpcm) Feb 2 2001 12:08:32 Installed devices: pcm1: at io 0x534 irq 5 drq 1:0 (1p/1r channels duplex) The machine is a Pentium II 333MHz, and I never had any problems with the sound distorting while playing MP3s in X-windows when I was running 4.2-STABLE. Also, I used to run KDE, now I use fvwm2, and the machine is not loaded down at all... (The CPU is mainly idle when the sound distorts.) Like I mentioned earlier, I really only hear the sound distort when the mouse is moved quickly. I can actually *compile* ports and as long as I don't move the mouse, the sound is fine as far as I've noticed... The kernel messages only appear every few minutes. There were about 30-40 of them in /var/log/messages, usually occuring once or twice every few minutes. Anyone have any suggestions on what might be causing this problem? Like I said, it was fine under 4.2-STABLE. All of the hardware is exactly the same as it was then... -Chris To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
