Demian Martin napsal(a):
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?
How do you play the files? Do you use the hw or plug:hw device? IIRC, the standard-setup dmix resampler is 16-bit only.
I did tests with SPDIF OUT/IN and found it bit-perfect, for 24bit too.
Regular ICE1724 cards do not output 176.4kHz SPDIF, only 88.2kHz. But Juli is not affected by that bug.
