The incapability of selecting the forth alternative disappeared when I
changed
val = ucontrol->value.enumerated.item[0] % 3;
to
val = ucontrol->value.enumerated.item[0] % 4;
on line 1758.
That is probably a bug, but rme32.c has other mysterious parts like:
1731 uinfo->value.enumerated.items = 4;
1732 if (uinfo->value.enumerated.item > 3) {
1733 uinfo->value.enumerated.item = 3;
1734 }
I am not capable of debugging alsa drivers (yet) and there is likely to
be a reason why some one wrote it that way. I suspect that it has to do
with compability with RME 32 but this is probably out of the scope of
the LAU-list anyway.
Thanks.
