Seem to be related to this issue in portaudio: https://app.assembla.com/spaces/portaudio/tickets/268/details
Unfortunately, no fix where committed to portaudio since that time.
Sorry, but there is not much we as UltraStar Deluxe developers can do to fix this problem. Please try to find a workaround yourself and then report this here, so other users with the same problem might see what they could try. Thank you! The issue will be closed (as there is nothing to be done in USDX), but you can still write comments, keep us up to date and discuss this problem.
Patches can be found on the Portaudio mailing list: https://lists.columbia.edu/pipermail/portaudio/2019-January/001734.html https://lists.columbia.edu/pipermail/portaudio/2019-July/001888.html The discussion on the mailing list has died off months ago.
The problem is caused by audio data being consumed or produced by USDX slower than necessary to keep up with the sampling rate.
in that case it might be a sampling rate mismatch.
Core dump while in "Record panel". Running on latest git/master, Ubuntu.
