| 2 | * ALSA driver for the Aureal Vortex family of soundprocessors.
|
|---|
| 3 | * Author: Manuel Jander (mjander@embedded.cl)
|
|---|
| 4 | *
|
|---|
| 5 | * This driver is the result of the OpenVortex Project from Savannah
|
|---|
| 6 | * (savannah.nongnu.org/projects/openvortex). I would like to thank
|
|---|
| 7 | * the developers of OpenVortex, Jeff Muizelar and Kester Maddock, from
|
|---|
| 8 | * whom i got plenty of help, and their codebase was invaluable.
|
|---|
| 9 | * Thanks to the ALSA developers, they helped a lot working out
|
|---|
| 10 | * the ALSA part.
|
|---|
| 11 | * Thanks also to Sourceforge for maintaining the old binary drivers,
|
|---|
| 12 | * and the forum, where developers could comunicate.
|
|---|
| 13 | *
|
|---|
| 14 | * Now at least i can play Legacy DOOM with MIDI music :-)
