[Scummvm-devel] Need some help with crash in COMI audio handling!

[Lars Persson]

Hi!
Thanks for the input. I will investigate the Mutex implementation in my SDL port, it might waiting in a wrong way perhaps. 

Cheers
Lars

> COMI, just like FT and The Dig, uses iMuse Digital. This uses a Timer callback (see TimerManager) to control various audio stuff. This runs in addition to the mixer "thread" (actually, whether this is a thread or a callback or whatever depends on the backend), and the main "thread".

If the Symbian port does not provide "real" threads to implement the OSystem timer callback, then this might indeed lead to problems. Though this is purely speculative from my point of view. I am not sure how this would fit with the symptoms you describe either.
