Description
On both x86 and x86_64, mplayer segfaults after pausing if it cannot reacquire sound devices with OSS audio plugin.
This happens for a long time (tested with both 1.0-1.rc2 and r28387 snapshot).
See GDB trace at https://qa.mandriva.com/attachment.cgi?id=12258
GDB show that it hapylly tries FD_SET() an invalid file descriptor because it hadn't tested whether open() failed or not (returning -1).
Despite having detected that situation:
Fatal error: * CANNOT RE-OPEN / RESET AUDIO DEVICE * Device or resource busy
Program received signal SIGSEGV, Segmentation fault.

509 FD_SET(audio_fd, &rfds);

Looks like this was fixed at some point since r31086 loooks OK
