I also have an A20p running FreeBSD-4.2 STABLE. Here's my findings: 1- Tried the pcm driver: no success 2- Tried the OSS driver from 4Front tech. (http://www.opensound.com/) I was able to get some sound with the demo driver, but the system hangs when I start the X server. The reason is that the A20p shares the same IRQ between the graphics adapter, a pcmcia bus and the sound card. You can go in the BIOS under the PCI configuration to select the IRQ per PCI bus, but the it seems that the sound/pcmcia/graphics are stuck on the same PCI bus (I've put irq 5 for the 1st PCI bus): /kernel: pci1: <ATI model 4c46 graphics accelerator> at 0.0 irq 5 /kernel: pcic-pci0: <TI PCI-1450 PCI-CardBus Bridge> mem 0x50000000-0x50000fff irq 5 at device 2.0 on pci0 /kernel: csa0: <Crystal Semiconductor CS4614/4622/4624 Audio accelerator/4280 Audio controller> mem 0xf0000000-0xf00fffff, 0xf0122000-0xf0122fff irq 5 at device 5.0 on pci0 Also note that you have to deactivate the BIOS APM support (see url below) I would really love to get that sound card running. Question is: can FreeBSD support a sound device that shares its IRQ ? A collegue of mine has the same laptop running Linux and the sound device works. Check out http://www.zhlive.ch/zhl_contents_linux.html for more info If anyone has more info, please post to the list. Florent.
