Comment 2 Geyang Kong 2012-05-31 05:08:41 UTC 
This bug can only be reproduced by es1370 audio device, others will be OK.
Comment 4 RHEL Program Management 2012-07-10 06:58:34 UTC 
This request was not resolved in time for the current release.
Red Hat invites you to ask your support representative to
propose this request, if still desired, for consideration in
the next release of Red Hat Enterprise Linux.
Comment 5 RHEL Program Management 2012-07-11 02:01:44 UTC 
This request was erroneously removed from consideration in Red Hat Enterprise Linux 6.4, which is currently under development.  This request will be evaluated for inclusion in Red Hat Enterprise Linux 6.4.
Comment 6 Daniel Berrangé 2012-07-26 17:41:58 UTC 
Given comment #2, this could well be a bug in the QEMU hardware emulation for that device type.
Comment 9 Marc-Andre Lureau 2013-05-08 15:39:13 UTC 
Since it's only with es1370 audio device, and this is spice related it can't be filed under virt-viewer. There is a qemu bug 949241 for it already, closing as dup
