I have the driver working fine for sample rates from 44.1K to 196K however
it seems to be truncating the data to 16 bits. I wasn't sure until I started
testing with the HRx 176.4K 24 bit files that have an embedded HDCD flag in
the LSB. The files work OK on Windoze systems (with a lot of low level
settings tweaked) and they play fine but the flag isn't detected by a system
that can detect them. Further looking at the data stream with a scope it
seems the last 8 bits aren't changing. Is there anything I can do to control
the driver to confirm this problem or change the playback settings to make
it work?
