DTS audio conversion fails with v7.30

[rainman74]

I have tested several videos and with all of them the following error message appears towards the end of the conversion process and the video is not written correctly (there are always a few seconds missing at the end and the index - e.g. length information - is also missing).

Command line: nvencc64.exe --avhw -i "in.mkv" -c hevc --profile main --level auto --preset quality --qvbr 28 --aq-temporal --aq-strength 0 --lookahead 32 --bref-mode middle --audio-codec ac3 --audio-bitrate 384 --sub-copy --chapter-copy -o "out.mkv"

Output with error: avcuvid: --sub-copy/--vpp-subburn is set, but no subtitle stream found.
