 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

+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

-/***************************************************************************************************
-*
-* 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?
