Dear FreeBSD users, there is something wrong with my soundcard or my harddisk. When I play some sound (usualy using mpg123), it slashes/cracks(?) whenever my harddisk works. I think the problem is with DMA. I compiled my own kernel. First I commented out lots of choices in the GENERAL one and it worked (the kernel). Then I added these lines to my kernel configuration: device pcm device sbc as written in the FreeBSD handbook. Ok, here are some lines from dmesg: atapci0: port 0x4000-0x400f,0x374-0x377,0x170-0x177, 0x3f4-0x3f7,0x1f0-0x1f7 irq 14 at device 1.1 on pci0 ata0: at 0x1f0 irq 14 on atapci0 sbc0: at port 0x220-0x22f,0x388-0x38b,0x330-0x331 irq 5 drq 1,0 on isa0 pcm0: on sbc0 ad0: 14649MB [29765/16/63] at ata0-master UDMA33 I really have no idea where the problem is. But the same problem I had under Linux, when I turned on dma transfer (using hdparm). With Windows95 it worked but I don't know if the disk used UDMA. Btw, the sound card is on motherboard. -- Marian Cerny cerny@spnv.sk To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
