<pre>Creating this bug to track volume-change issues between guest and client. I
believe that big part of these issues are in QEMU that calls spice-server with
the wrong volume value (proportionally) but the solution could be done in the
using vdagent to check/sync audio properly;
This is also related to <a href="https://bugzilla.redhat.com/show_bug.cgi?id=1012868">https://bugzilla.redhat.com/show_bug.cgi?id=1012868</a> as
we are trying to sync volume between client and guest using the agent but the
server sends volume-change with different value of the one just set by the
agent and usually higher then the right value.
Main issues when setting guest volume;
1) F21(client) and F21(guest) - The value sent by spice-server is always higher
then the updated value in the guest;
2) F21(client) and Windows 7(guest) - Same as 1)
3) Windows 7(client) to Windows XP(guest): Setting 100% in the guest is 74% in
the client;
Example:
client: Fedora 21 (all spice components from git master)
guest: Fedora 21 (latests from f21)
volume in both before: 32768 or -18.06 dB (50%)
setting volume with `pacmd set-sink-volume 0 volume`
setting 10000 (around 15%), spice-gtk receives 22102 (33%)
setting 40000 (around 61%), spice-gtk receives 53970 (82%)
setting 50000 (around 76%), spice-gtk receives 59110 (90%)
setting 60000 (around 91%), spice-gtk receives 63736 (97%)
setting 65000 hits the maximum in the client (65536)</pre>
