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.

When a probe error occurs or when the driver obviously assigns a
mismatched model, it'd be helpful to load the driver with
`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
configuration via hwdep sysfs file if hda-reconfig option is enabled.

This is the meaning of the parameters:
io--I/O address of the Windows Sound System (normally 0x534)
irq--IRQ of this device
dma and dma2--DMA channels (DMA2 may be 0)
On some cards, the board attempts to do non-PnP setup, and fails. If you
have problems, use Linux' PnP facilities.
To get MIDI facilities add
insmod opl3 io=*

/***************************************************************************************************
*
* To understand what Alsa Drivers should be doing look at "Writing an Alsa Driver" by Takashi Iwai
* available in the Alsa doc section on the website
*
* A few notes to make things clearer. The UDA1341 is hooked up to Serial port 4 on the SA1100.
* We are using SSP mode to talk to the UDA1341. The UDA1341 bit & wordselect clocks are generated
* by this UART. Unfortunately, the clock only runs if the transmit buffer has something in it.
* So, if we are just recording, we feed the transmit DMA stream a bunch of 0x0000 so that the
* transmit buffer is full and the clock keeps going. The zeroes come from FLUSH_BASE_PHYS which
* is a mem loc that always decodes to 0's w/ no off chip access.
*
* Some alsa terminology:
* frame => num_channels * sample_size e.g stereo 16 bit is 2 * 16 = 32 bytes
* period => the least number of bytes that will generate an interrupt e.g. we have a 1024 byte
* buffer and 4 periods in the runtime structure this means we'll get an int every 256
* bytes or 4 times per buffer.
* A number of the sizes are in frames rather than bytes, use frames_to_bytes and
* bytes_to_frames to convert. The easiest way to tell the units is to look at the
* type i.e. runtime-> buffer_size is in frames and its type is snd_pcm_uframes_t
*
* Notes about the pointer fxn:
* The pointer fxn needs to return the offset into the dma buffer in frames.
* Interrupts must be blocked before calling the dma_get_pos fxn to avoid race with interrupts.
*
* Notes about pause/resume
* Implementing this would be complicated so it's skipped. The problem case is:
* A full duplex connection is going, then play is paused. At this point you need to start xmitting
* 0's to keep the record active which means you cant just freeze the dma and resume it later you'd
* need to save off the dma info, and restore it properly on a resume. Yeach!
*
* Notes about transfer methods:
* The async write calls fail. I probably need to implement something else to support them?
