Works fine for me! Did you check twice that your modified vgabios is actually loaded by qemu (e.g. via strace)? Moreover, does sound work at all with your qemu? The image I tried [1] issues two beeps after loading (obviously via direct hw access) - a good way to check general support. Note that one reason for broken host sound with qemu can be OSS. For that reason I always configure my qemu with --audio-drv-list=alsa. Jan PS: Your patch was mangled by your mail client. Fortunately, it was small enough for manual fixing.

Thats a good hint :) Seems i used to compile qemu without "--audio-drv-list". Since "dsound" and "fmod" drivers don't compile here (i likely miss some libs in my mingw), i used "sdl". Now i can hear those two beeps with the image you suggested. Tho those are coming thru my sound card and not the hosts pc speaker (even with "-soundhw pcspk", but maybe that option means something different). With INT 10h AH=0Eh i now can hear a beep too, but it doesn't stop and qemu somewhat freezes. > Jan > > PS: Your patch was mangled by your mail client.

Unfortunatelly Windows Mail tends to do this and i failed to find an option to fix it. - Sebastian -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Here's a nice tutorial Kazu made that will probably help you: http://www.h7.dion.ne.jp/~qemu-win/Audio-en.html > Now i can hear those two beeps with the image you suggested.

And it will always come through your soundcard. pcspk is not a passthrough thing. > With INT 10h AH=0Eh i now can hear a beep too, but it doesn't stop and qemu > somewhat freezes.

With this INT 10h function qemu should beep once, but it does loop the beep infinitely. Normally i can exit qemu by clicking on the [x] window close "icon", but while it does endlessly beep that doesn't work (vista says process doesn't respond). Using "quit" in the monitor window doesn't work either. - Sebastian -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
