No, ff5414990645653bf43bf64adfc1ca77ffb9edcb is not in 0.12.3. Oh well. Relevant link from the commit: http://bugs.gentoo.org/show_bug.cgi?id=294269 (and the commit itself, for example: http://git.kernel.org/?p=virt/kvm/qemu-kvm.git;a=commit;h=ff5414990645653bf43bf64adfc1ca77ffb9edcb ) It talks about sdl output. I just tried here with QEMU_AUDIO_DRV=sdl, and can reproduce it. In Debian we build with --audio-drv-list="alsa oss sdl pa" so the default should be alsa not sdl. Christian, can you tell us how you've set it to SDL? Do you have $QEMU_AUDIO_DRV set? Here's my -audio-help output, from the system where I can finally reproduce the thing... but is it really interesting?
