So, basically, ESI cannot help us.
I am amazed that they can write any sort of driver without some sort of 
But I do know it does happen, because I have received datasheets that 
were only written years after a particular sound card was first sold.
I would like to stress, that the datasheet does not have to be perfect. 
We would be quite happy if it has spelling mistakes in, and some wrongly 
labeled registers.
I have received datasheets from other manufactures where some engineer 
has just scribbled some notes on the back of a piece of paper.
The important point I am trying to make is that the data about the sound 
card does not have to prettily laid out or even 100% accurate. We just 
need something that helps save us time in developing a driver. Ideally, 
it should be in some editable electronic format, so that ALSA developers 
can edit and correct errors in the document as and when they find them.

Now, if ESI cannot even provide this, we should highlight ESI in RED in 
the sound card matrix.

Kind Regards
