Mic settings did not reduce the static altho I have a mic plugged in. With the delay thru the sound system I have an expensive reverb. Its still there and can be heard over the volume of the 4 fans and 7200 RPM HD in my system. Speakers and system are under the table too. > > Without telling PnP anything special it was detected and appears to work > > (cat /usr/local/lib/exmh-2.0.2/drip.au > /dev/audio) But I think the dma > > assignment needs manual attention?

PnP apparently knows what its doing: Probing for PnP devices: CSN 1 Vendor ID: YMH0020 [0x2000a865] Serial 0xffffffff Comp ID: PNPb02f [0x2fb0d041] mss_attach <Yamaha SA2>1 at 0x530 irq 5 dma 0:1 flags 0x11 setting up yamaha registers set yamaha master volume to max pcm1 (CS423x/Yamaha/AD1816 <Yamaha SA2> sn 0xffffffff) at 0x530-0x537 irq 5 drq 0 flags 0x11 on isa While the AW37 never produced correct sounds, it never generated this static. Almost couldn't sleep last night as I thought I'd found the source of all my sound problems (this static and the AW37 problem) and couldn't wait to try it. Nope. Had the great idea I was plugging amplified speakers (line level inputs) into 8 ohm jacks. There *are* line level inputs and mic inputs on the sound cards but apparently the speaker outputs are line level too. Oh well, it was a good idea. -- David Kelly N4HHE, dkelly@nospam.hiwaay.net ===================================================================== The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.
