list, First, I solved the problem I posted about a few weeks ago wtional aeronautical beacons is being phased out and the frequencies also arhere I was having trouble configuring the sound on my laptop. For some reason, installing udev fixed it. Now I'm having a different problem in a different computer. In this other computer, I have an ISA soundcard. When it works, it uses two DMA numbers, 1 and 5. /proc/dma says: 1: SoundBlaster - 8bit 4: cascade 5: SoundBlaster - 16bit . I guess cascade is shared by the PCI devices. For PCI devices, I have a video card, a NIC, a SCSI controller, the south bridge, and a TV tuner card. The TV card has been causing the most trouble, but there are other problems too. If I use an AGP video card instead of the PCI one, the computer hangs at boot just after the sound card has been initialized. When I have the TV card in, the sound card driver doesn't get loaded. I can modprobe it manually, but it still doesn't work. When I watch TV, it is very unstable and if I try to move the window around or use a control button there will be some video problem like where the window or button was will turn orange or the computer will hang. The bttv driver FAQ indicates that there may be DMA problems: http://linux.bytesex.org/v4l2/faq.html#oops It says to disable DMA for IDE. Is there some better way? The DMA channels are supposed to be shared, right? If I have to disable DMA for IDE how do I do it? In Documentation/ide.txt of the kernel sources, I can see where it says to argue to the kernel for a particular drive to use DMA, but I can't see how to disable DMA. Anyway, DMA exists for a reason I guess, so I'd prefer to make it work if possible. This message indicates that my chipset, VIA MVP3, may have DMA problems: http://www.ussg.iu.edu/hypermail/linux/kernel/0308.1/0375.html . So do I just have a chipset that doesn't work well with DMA or what?
Also, the tuner on my card that is autodetected is the wrong one because the channels are offset, so I need to manually argue for a different tuner. There is nothing in /etc/modprobe.d/ about bttv, or my NIC or SCSI controller for that matter. I suppose the NIC module is called when bringing up network interfaces, and the SCSI controller module is called when bringing up drives, but when is bttv called? How do I give arguments to it? Thanks in advance. Nick _______________________________________________ vox-tech mailing list [EMAIL PROTECTED] http://lists.lugod.org/mailman/listinfo/vox-tech
