SubjectGravis Ultrasound and I/O errors....
DateMon, 25 Nov 1996 16:35:56 -0500 (GMT-0500)
Have noticed this in the few recent kernels...
I have a 486/40 with a GUS classic.  When I try to run a program that uses
the sound car, I get the following error (Most noticably in doom 1.8)

	[55] 16:32 ctx-apex:~# cat /dev/sound
	Sound  DMA (input) timed out - IRQ/DRQ config error?
	cat: /dev/sound: I/O error
	[56] 16:32 ctx-apex:~#

/dev/sndstat states the following...

	Sound Driver:3.7-beta12-961115 (Sun Nov 24 20:56:17 GMT-0500 1996 bin,
	Linux ctx-apex 2.1.12 #6 Sun Nov 24 20:32:15 GMT-0500 1996 i486)
	Kernel: Linux ctx-apex 2.1.13 #8 Mon Nov 25 15:53:49 GMT-0500 1996 i486
	Config options: 0

	Installed drivers:
	Type 4: Gravis Ultrasound
	Type 25: GUS PnP

	Card config:
	Gravis Ultrasound at 0x220 irq 11 drq 1

	Audio devices:
	0: Gravis UltraSound

	Synth devices:
	0: Gravis UltraSound 3.4 (1024k)

	Midi devices:
	0: Gravis UltraSound Midi

	Timers:
	0: System clock

	Mixers:
	0: Gravis Ultrasound

Why the two installed drivers?  And why does a cat /dev/midi0 report the I/O
error?  The same error:

	[107] 16:33 ctx-apex:/dos/ultrasnd/midi# cat /dev/dsp
	Sound: DMA (input) timed out - IRQ/DRQ config error?
	cat: /dev/dsp: I/O error

happens when cat'ing the /dev/dsp file...

lrwxrwxrwx   1 root     bin             9 Aug 14 14:28 /dev/dsp -> /dev/dsp0

crw-rw-rw-   1 root     bin       14,  18 Aug 14 14:28 /dev/midi01
crw-rw-rw-   1 root     bin       14,  34 Aug 14 14:28 /dev/midi02
crw-rw-rw-   1 root     bin       14,  50 Aug 14 14:28 /dev/midi03

Any help would be appreciated!
