According to my test, my guest OS also can support for volume control
even I don't apply the patch to my code. I run my Ubuntu guest OS via
the following command:
qemu-system-x86_64 -M pc --enable-kvm -m 512 -smp 1 -name Ubuntu
-localtime -boot c -drive file=ubuntu.img,if=virtio,index=0 -vga cirrus
-chardev stdio,id=mon0 -mon chardev=mon0,mode=readline -chardev
socket,id=mon1,host=localhost,port=5554,server,nowait,telnet -mon
chardev=mon1,mode=control -soundhw ac97
By the way, my host OS is also Ubuntu 11.04 and I haven't apply your
patch [PATCH 04/11] and [PATCH 05/11] for hw/ac97.c to my code. Are
there any problems for my test?
Best Regards
Wayne Gao
