Re: [Opensound-devel] osscore: #1 launch_output, #2 Output interrupt & #3 Internel error

[Hannu S. <ha...@vo...>]

Hi,

I don't know if the bug is in Java or in the player. However this is 
very typical problem with multithreaded applications. There is one 
thread playing or recording audio and at the same time some other thread 
makes ioctl calls on the device or even closes it. In this case it looks 
like the device has been closed while the playing thread is calling 
write(). This doesn't make any sense and it's absolutely forbidden.

Best regards,

Hannu
