Description qube99 2005-05-05 21:17:01 UTC

Qemu's soundblaster 16 emulation only supports writing out.  As such, its
ossaudio.c file grabbing read-write access isn't a good thing.  Some of us
actually want to use the one read hook for something else.

Reproducible: Always

Changes O_RDWR to O_WRONLY in ossaudio.c

This is a trivial patch and should be applyable any time after unpacking.

did you try to push it upstream?

Comment 3 Marco Matthies 2006-05-07 15:25:58 UTC

This bug has been fixed in upstream since July 24, 2005.
(Not sure if it's 0.7.1 or 0.7.2 where the fix appeared.)

I think this bug can be closed.

See:
http://cvs.savannah.nongnu.org/viewcvs/qemu/audio/ossaudio.c?root=qemu&r1=1.4&r2=1.5
