[EMU10K1] Bug in EMU10K1

[Jeffrey H. Ingber]

I'm having difficulty making an E-MU E-Card work with any degree of
success under Linux.  Accoring to the notes in the driver, this card is
listed as supported:

drivers/sound/emu10k1/main.c
 *      0.3 Fixed mixer routing bug, added APS, joystick support.
 *	0.7 Support for the Emu-APS. Bug fixes for voice cache setup, mmaped
sound + poll().
 
The modules load, mixer loads (but only has controls for 'Master'
and 'DSP'), can use audio applications but don't hear sound.  System
crashes (hard-lock, no SysReq, etc.) if audio is stoped and restarted.

I had no trouble making a vanilla Live work with any of these drivers.  

Driver is stock RH kernel from 2.4.9-12 with and without SMP - also
tried CVS
driver from Creative (11/02/2001) with same results.  System is IBM
NetFinity 5600 with 2x
PIII's @ 666 MHz.  Card is an E-MU E-Card without E-Drive.
