pure alsa crashes after less than an hour

Opened this issue · 4 comments

Debian Buster, pyenv with Python 3.7.4. Pure alsa no pulseaudio.

Runs pretty well for at least 30 minutes, then suddenly crashes.

Hmm, looking deeper this seems to be a PortAudio issue: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=944509

Hi Dromer,

We have done quite a bit of development and documentation work. Have a look at the readme on: https://github.com/ahodges9/LedFx/tree/dev & https://ledfx.readthedocs.io/en/docs/index.html
Can I ask you to try the LedFx Exe version 0.0.3: https://ledfx.app/download/ - only x64 bit environment

Your welcome to join the LedFx community on Discord and we can help you out from there: https://discord.com/invite/wJ755dY

What do you expect me to do with a .exe?

Will try the latest master (or I guess dev? since master builds are failing) and see if it works any better :)

Yeah still have major issues. With alsa it works for a couple seconds and then fails. Jack doesn't work at all.

There is more output when it fails, so maybe this helps you. Basically still the same failure which may or may not have to do with PortAudio:
