Hi,

I am attempting to add ADAV801 codec support to my 2.6.35 kernel to be used with an ARM processor. I can see that there is a mainlined adav80x.c driver that appears at kernel version 3.1, I have had a quick look at back-porting the driver but this looks as though it could get quite messy.

However, I did come across an older ADAV801 driver which looks a lot simpler, but I cannot find it in previous mainlined kernel versions, http://www.spinics.net/lists/alsa-devel/msg36465.html, so I thought I would use this as a basis for my own driver.

_From what I understand from the datasheet and the way the older driver has configured the registers on the ADAV801 I should be able to see some data on the record outputs, however this is not the case. Could anyone confirm whether or not this driver dated August 2010 is OK to use? Or perhaps some advice on areas to look at that may be preventing the CODEC from manipulating and outputting the digital conversion.

Best regards

Wayne
