Configurable Sound Pass-through
A sound device can now be detected as a microphone or a speaker in the guest system (in addition to being detected as line-in and line-out). Sound devices can now function properly in guest applications that accept only certain types of input for voice recording and audio.

scratch build: http://brewweb.devel.redhat.com/brew/taskinfo?taskID=4129196 Testing: Use "-device hda-micro" instead of "-device hda-duplex" on the qemu-kvm command line. Expected behavior: Windows7 starts hardware detection on first boot with hda-micro active. Start -> Control Panel -> Hardware and Sound -> Manage audio devices -> Recording tab -> see microphone instead of line-in there. Not too good results, qemu-kvm segfaulted while windows was booting up with the following message in syslog: Mar 8 10:28:22 rhevh2 kernel: qemu-kvm[30366]: segfault at 50 ip 00007fdac66931e5 sp 00007fdabee2f9a0 error 4 in libspice-server.so.1.0.2[7fdac665f000+e2000] Running this on rhev-H hosts, so not much more info available... Any chance to pickup+install latest spice-server package from brew on that machine and see how it goes then? Failing that I'll go build a 6.2 version. On the bright side, with spice-server-0.10.1-4.el6, qemu-kvm no longer crashes. On the not-so-bright side, is there any (easy) way I can test this in a RHEV environment? I.e. start a VM with the hda-micro parameter? Patches are merged upstream: http://git.qemu.org/?p=qemu.git;a=commitdiff;h=d0c2bbb9f04925eeda9948586aa382ccf68e26e7 http://git.qemu.org/?p=qemu.git;a=commitdiff;h=201100656986735250ed4cd47be6b8a31c771763 http://git.qemu.org/?p=qemu.git;a=commitdiff;h=ec4a804792ea20f716371a0a661efc9ec15c7ff0 They create a new hda-micro codec which advertises speaker+microphone instead of line-in/out. Hi all, I reproduce this issue on qemu-kvm-0.12.1.2-2.295.el6.x86_64 as following. Version-Release number of selected component (if applicable): host info: # uname -r && rpm -q qemu-kvm 2.6.32-278.el6.x86_64 qemu-kvm-0.12.1.2-2.295.el6.x86_64 guest info: windows_7_ultimate_sp1_x64 Steps to Reproduce: 1.boot a windows 7 guest with "-device hda-duplex". eg:<qemu-kvm-command-line>-device intel-hda,id=sound0,bus=pci.0 -device hda-duplex 2.check "Start -> Control Panel -> Hardware and Sound -> Manage audio devices -> Recording tab". Reproduce results: after the step 2, we could see "line-in" device in Recording tab. I also test the Gerd's build Comment #8 with the same steps using "-device hda-micro" instead of "-device hda-duplex" on the qemu-kvm command line. The test results is that we could see "Microphone" instead of "line-in" device there. Best wish. sluo Verify this bug on qemu-kvm-0.12.1.2-2.334.el6.x86_64. host info: # uname -r && rpm -q qemu-kvm 2.6.32-342.el6.x86_64 qemu-kvm-0.12.1.2-2.334.el6.x86_64 guest info: windows_7_ultimate_sp1_x64 steps: the same as comment #9 Result: we could see "Microphone" device in Recording tab instead of "line-in" there, "Start -> Control Panel -> Hardware and Sound -> Manage audio devices -> Recording tab". Base on above and comment #9, this bug was fixed correctly. Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
