How far is this binary from working? http://mirror.trouble-free.net/3ware/tw_cli-linux-x86_64-9.5.3.tgz

For vchan_autoconfig, as you've seen there is a test for precision frequency and validbits the problem with vs(4) and some dec machines using a7930 audio codecs is that the hardware precision or the first filter in the case of vs(4) is equal to 4 bits and the top most filter SLINEAR is 16 bits so auto config of audio would fail. By using the null filter as the first one closest to hardware with precision and validbits set to 16 -> then the acdpm filter -> then slinear auto config will succeed as the null filter reports 16 bits and the final slinear filter reports 16 bits. I would really like to do away with the null_filter and vchan_autoconfig and just set it to 16 bit 48000 Hz stereo. But to do that drivers/cards that don't support this would have to be changed to use auconv/auconv_set_converter. Ideally all sound drivers should use auconv as vchan_autoconfig is a hack.
