Actually this is bad. Device should be opened with AC3 format. You are just lucky that your receiver is clever enough to detect unmarked AC3 input stream instead of PCM data. Mine is not. Probably reason is also in Soft PCM vol. I had no such messages on my tests. My AD1988 codec has real hardware digital volume control, so Soft PCM vol is not used. -- Alexander Motin
