Doc Text:	Previously, users could not control a Windows 7 virtual machine's sound volume with the guest volume controls. This occurred because the Windows client's audio back-end (GStreamer) did not have mute and volume control capabilities for playback and record. This was fixed by updating GStreamer to version 1.0, and implementing volume and mute capabilities in the directsoundsrc element. Volume control on Windows virtual machines now works as expected.

Description Amador Pahim 2014-09-03 12:18:34 UTC

Using client volume control, I can control Guest sound volume, but I'm not able to control guest volume using guest volume controller in some envs: 

Unable to control sound volume inside the guest
- Client Win7, vier-viewer 0.5.6-25(rhev current) / Guest Win7, RHEV-Spice-Agent 4.11.2
- Client Win7, vier-viewer 1.0256(newest available msi) / Guest Win7, RHEV-Spice-Agent 4.11.2

But using client on Fedora20 or using a RHEL7 Guest, I can control guest sound volume inside the guest:
- Client Win7, vier-viewer 0.5.6-25 / Guest RHEL7
- Client Fedora20, virt-viewer-0.6.0-1.fc20.x86_64 / Guest Win7, RHEV-Spice-Agent 4.11.2

Comment 1 Marc-Andre Lureau 2014-09-03 12:36:13 UTC

The problems stems from the audio sink/src not implementing the GstStreamVolume interface.

In >1.0, directsoundsink implements it, however directsoundsrc is still missing volume control.

Perhaps we should first rebase gstreamer to 1.x series, and fix directsoundsrc upstream.

this all sounds too late for 3.5

Comment 3 Victor Toso 2015-02-19 14:14:18 UTC

Just an update: Last upstream release of virt-viewer is using gstreamer1 and you can control guest playback audio inside the guest;

For the record audio (directsoundsrc), there is a patch upstream at:
https://bugzilla.gnome.org/show_bug.cgi?id=744383

Comment 4 Victor Toso 2015-04-01 08:18:10 UTC

The patch for directsoundsrc element is now upstream.

Closing this bug as NEXTRELEASE as this patch should be available in next virt-viewer windows release.

If you find any problems related to volume control, please open a new bug for it.

Comment 5 Victor Toso 2015-04-01 08:46:28 UTC

Closing as NEXTRELEASE is not right. Sorry. Moving it to POST.

The bz for directsoundsrc fix is
https://bugzilla.gnome.org/show_bug.cgi?id=744383

The patch is upstream on gst-plugins-bad hash
1b564bfb8b0db43a24cf311dca24038558b80a68

It should be included in version 1.4.6
