When I try to cat /dev/audio > foo I get nothing in foo, and I was getting an error message ending with "IRQ conflict?" that I can't seem to make happen today, or I'd include it. Was getting 2 errors, both with "DSP blah blah" in 'em. (No, I don't have any actual IRQ conflicts.) Here's my dmesg output: pcm0 at 0x220 irq 5 drq 1 on isa ESS1868 (rev 11) Here's 'cat /dev/sndstat' FreeBSD Audio Driver (981002) Oct 18 1998 02:37:46 Installed devices: pcm0: at 0x220 irq 5 dma 1:1 And from my config file: device pcm0 at isa? port 0x220 tty irq 5 drq 1 flags 0x0 vector pcmintr This is all under current cvsupped yesterday. I used to use the voxware driver with the same settings and cat /dev/audio > foo used to work, at least. (though lots of other things didn't) I was under the impression that this ESS was only half-duplex, or am I wrong and do I need to set 2 dma channels? This chip is supposed to also emulate MSS, but I was under the impression that MSS was full-duplex. Am I mistaken? Off the top of my head, I think that the capabilities of the chip emulating MSS were supposed to be better than emulating the SB -- 16bit vs 8bit sound, maybe? Is it possible to make the chip work as MSS? To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-multimedia" in the body of the message
