ALSA error: Access violoation when trying to start the game

[speich]

After compiling when I try to start the game, I get the following error: /usr/local/bin/ultrastardx ALSA lib pcm.c:2642:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.rear ALSA lib pcm.c:2642:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.center_lfe ALSA lib pcm.c:2642:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.side ALSA lib pcm_route.c:869:(find_matching_chmap) Found no matching channel map ALSA lib pcm_oss.c:377:(_snd_pcm_oss_open) Unknown field port ALSA lib pcm_oss.c:377:(_snd_pcm_oss_open) Unknown field port ALSA lib pcm_usb_stream.c:486:(_snd_pcm_usb_stream_open) Invalid type for card ALSA lib pcm_usb_stream.c:486:(_snd_pcm_usb_stream_open) Invalid type for card An unhandled exception occurred at $00007F6BB2969623: EAccessViolation: Access violation $00007F6BB2969623

USDX version v2020.4.0 Linux Mint 20

sorry, but this does not look like a problem regarding USDX, but instead is most likely a problem with your audio setup / audio sink configuration. You might be able to get support from some Linux Mint users forum for this.

Please feel free to reopen this issue here, if you end up discovering that this is actually a problem of how the compile scripts detect your audio setup.

We've had crashes like this before in #473, #496 and #396. Note that $00007F6BB2969623 is inside a library, not inside USDX. My guess is that it's PortAudio that crashes. Try building --without-portaudio.

Thanks for the tip. When building with ./configure --without-portaudio the error goes away :-)
