Since 2.6.29 kernel, the driver has a more robust probing method, so
this error might happen rarely, though.
+On a machine with a broken BIOS, sometimes you need to force the
+driver to probe the codec slots the hardware doesn't report for use.
+In such a case, turn the bit 8 (0x100) of `probe_mask` option on.
+Then the rest 8 bits are passed as the codec slots to probe
+unconditionally. For example, `probe_mask=0x103` will force to probe
+the codec slots 0 and 1 no matter what the hardware reports.

There are some other useful options. See `--help` option output for

+When a probe error occurs or when the driver obviously assigns a
