Ibasso DC03 + DSD/PCM 32bit app crashes

Hello,
I’m using ibasso dc03 DAC via ASIO (official win drivers) and noticed some unpleasant bugs.

1)Current Audirvana Studio 1.5.5 10505 constantly crashes when playing DSD files or “heavy” PCM 32 bit ones. Tracks are playing but the application crashes every time when track ends or I select a different one (or album) manually.

2)Native DSD is not supported for ibasso dc03 dac. DoP is the only way I can play DSD now, losing DSD256 functionality. Although in other players (jriver win, hiby android) it is supported and the DAC supports native dsd up to 256 too.
