I think I have found the change which reversed the channels.
Revision 1.44 of emu10k1.c, which added Audigy support, has the line
emu_wrptr(sc, v->vnum, FXRT, 0xd01c0000);
replaced with the following lines:
if (sc->audigy) {
emu_wrptr(sc, v->vnum, A_FXRT1, v->fxrt1);
emu_wrptr(sc, v->vnum, A_FXRT2, v->fxrt2);
emu_wrptr(sc, v->vnum, A_SENDAMOUNTS, 0);
}
else
emu_wrptr(sc, v->vnum, FXRT, v->fxrt1 << 16);
where v->fxrt1 << 16 == 0xd10c0000
I don't have Audigy, so I'm not sure if the problem affects Audigy cards
too. The order of the channels can't be tested by just altering mixer
settings. Here's a small program to test if the channels are reversed on
your sound card:
#include <sys/soundcard.h>
#include <fcntl.h>
#include <unistd.h>
int main(int argc, char **argv)
{
int fd = open("/dev/dsp", O_WRONLY), format = AFMT_S16_LE;
int channels = 2, rate = 22050, i;
/* 450 Hz sine wave on left channel, right channel silent */
unsigned char samples[] = {0, 0, 0, 0, 94, 16, 0, 0, 120, 32, 0, 0,
9, 48, 0, 0, 208, 62, 0, 0, 143, 76, 0, 0, 12, 89, 0, 0, 19, 100,
0, 0, 117, 109, 0, 0, 11, 117, 0, 0, 182, 122, 0, 0, 92, 126, 0,
0, 239, 127, 0, 0, 105, 127, 0, 0, 202, 124, 0, 0, 32, 120, 0, 0,
124, 113, 0, 0, 251, 104, 0, 0, 193, 94, 0, 0, 249, 82, 0, 0,
212, 69, 0, 0, 138, 55, 0, 0, 85, 40, 0, 0, 120, 24, 0, 0, 51, 8,
0, 0, 205, 247, 0, 0, 136, 231, 0, 0, 171, 215, 0, 0, 118, 200,
0, 0, 44, 186, 0, 0, 7, 173, 0, 0, 63, 161, 0, 0, 5, 151, 0, 0,
132, 142, 0, 0, 224, 135, 0, 0, 54, 131, 0, 0, 151, 128, 0, 0,
17, 128, 0, 0, 164, 129, 0, 0, 74, 133, 0, 0, 245, 138, 0, 0,
139, 146, 0, 0, 237, 155, 0, 0, 244, 166, 0, 0, 113, 179, 0, 0,
48, 193, 0, 0, 247, 207, 0, 0, 136, 223, 0, 0, 162, 239, 0, 0};
ioctl(fd, SNDCTL_DSP_SETFMT,&format);
ioctl(fd, SNDCTL_DSP_CHANNELS,&channels);
ioctl(fd, SNDCTL_DSP_SPEED,&rate);
for(i=0;i<500;i++)
write(fd, &samples, sizeof(samples));
write(fd, &samples, 2); /* swap channels */
for(i=0;i<500;i++)
write(fd, &samples, sizeof(samples));
return 0;
}
You should hear a sound on the left channel followed by a sound on the
right channel. If you hear a sound on the right channel first, the
channels are reversed.

Owners of an audigy card should verify if it DTRT and report back.
