I played with 8233A ALC650 and:
1) this part of code is not working:
switch (runtime->channels) {
case 1: slots = (1<<0) | (1<<4); break;
case 2: slots = (1<<0) | (2<<4); break;
case 3: slots = (1<<0) | (2<<4) | (5<<8); break;
case 4: slots = (1<<0) | (2<<4) | (3<<8) | (4<<12); break;
case 5: slots = (1<<0) | (2<<4) | (5<<8) | (3<<12) | (4<<16);
break;
case 6: slots = (1<<0) | (2<<4) | (5<<8) | (6<<12) | (3<<16)
| (4<<20); break;
default: slots = 0; break;
}
/* STOP index is never reached */
outl(0xff000000 | slots, VIADEV_REG(viadev,
OFFSET_STOP_IDX));
I think that 8233A uses this slots mapping and this can't be changed
with previous code. I changed
case 6: slots = (1<<0) | (2<<4) | (5<<8) | (6<<12) | (3<<16) |
(4<<20); break;
to
case 6: slots = (1<<0) | (2<<4) | (3<<8) | (4<<12) | (5<<16) |
(6<<20); break;
and this doesn't work (no change).
channels slots
1 - 3, 4
2 - 3, 4
4 - 3, 4, 7, 8
6 - 3, 4, 6, 9, 7, 8
