RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

RHEL >= 6.5 will have mixemu enabled by default. The HDA Audio device will be different in this case, so we need to handle new hardware machine versionning.
Leaving this bug open, and marked as blocking bug 895959, because this is more complicated than just adding a global property.

Reproduced this bug on qemu-kvm-1.5.3-9.el7.x86_64 and verified pass on qemu-kvm-1.5.3-31.el7.x86_64.
===================
Reproduction:
1. Boot up a win7-32 guest with sound device and spice with -M rhel6.4.0 on rhel7.0 host.
/usr/libexec/qemu-kvm ... -M rhel6.4.0 -spice port=5930,disable-ticketing -vga qxl -device intel-hda,id=sound0,bus=pci.0,addr=0x5 -device hda-duplex,id=sound0-codec0,bus=sound0.0,cad=0
2. Play some music inside guest.
3. Click the "mute/unmute" button in the right bottom of guest desktop.
Result: We could mute and unmute the sould within guest even the machine type is "-M rhel6.4.0".
===================
Verification:
Scenario 1:
(1) Boot up the win7 guest with with sound device and spice with *-M rhel6.4.0* on rhel7.0 host.
(2) Play some music inside guest.
(3) Click the "mute/unmute" button in the right bottom of guest desktop.
Result: The mute button does not work, it will keep the default.
Scenario 2:
(1) Boot up the win7 guest with with sound device and spice with *-M rhel6.5.0* on rhel7.0 host.
(2) Play some music inside guest.
(3) Click the "mute/unmute" button in the right bottom of guest desktop.
Result:
The mute button works, we could mute/unmute the sound.
Scenarios 3:
(1) Boot up the win7 guest with with sound device and spice with *-M pc* or *-M q35* on rhel7.0 host. (I tried both the cases)
(2) Play some music inside guest.
(3) Click the "mute/unmute" button in the right bottom of guest desktop.
Result:
The mute button works, we could mute/unmute the sound.
Scenario 4:
Migrate guest from rhel6.5 host -> rhel7.0 host with
-M rhel6.4.0 and sound device, connect guest with spice.
Result:
Migration finish successfully, mute/unmute button does not work always.
Scenario 5:
Migrate guest from rhel6.5 host -> rhel7.0 host with
-M rhel6.5.0 and sound device, connect guest with spice.
Result:
Migration finish successfully, mute/unmute button works. But I hit a new bug 1047265 in this scenario.
================
Based on above, I will change the status to verified. As the machine types loer than rhel6.4.0 does not use mixemu now. We could use bug 1047265 to track the new issue.
