Sound initialization complete
I have an ESS ES1888 that runs fine under both Win95 and WinNT 4.0.
When I try to use programs such as Wavplay with it under linux, it
repeates the message IRQ timeout every 1 second and does not complete
playing the wave file (plays a 15 second wave file in 4 seconds), and
skips like a scratched record in the first second for the full four
seconds. The ESS is detected regularly by all of my MS-DOS based games.
Any plans for 1888 support? It sure would be nice. Let me go get my
.config and /dev/sndstat... Oh, and workbone cdplaying works just fine.
2.1.42 kernel, multiple patches, but none in drivers/sound. Had this
problem since I started using linux on this computer, patched or not.

Would be nice to get this fixed. Haven't tested the MIDI, probably would
do the same thing.
