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.

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

`probe_only=1` option (at best after the cold reboot) and run

alsa-info at this state. With this option, the driver won't configure

the mixer and PCM but just tries to probe the codec slot. After

probing, the proc file is available, so you can get the raw codec

information before modified by the driver. Of course, the driver

isn't usable with `probe_only=1`. But you can continue the
