I'm co-teaching a class in the basics in max/msp and arduino and one of our students has a very strange bug on his laptop when using sfrecord~ or quickrecord.
When starting recordings it says:
"can't open file for async access, err -1"
"start requested without preceeding 'open'"
And when pressing stop it finally says:
"could not finish writing header for &, err -1
In the output directory there is a file created but it's almost empty. It's as if there is header and space has been allocated for the length of the recording but the file is corrupt.
He's running max on a pc laptop, latest version of max 5, windows xp, realtek soundcard with asio4all (also tried all the other sound drivers).
We've tried many things, disabling the firewall, changing sound driver, anything basically. Nothing works. I've never come across this error message before. The patch is running, outputting audio and the patch is a general example that we've been using without previous problems.
