[Qemu-devel] QEMU VNC Audio - All audio data null

[agraham <agraham@g-b.net>]

Hi Guys,

I've written a VNC client that implements the VNC QEMU Audio extensions. 
  Using QEMU 0.13 it works very very for remote sound, however after 
upgrading to QEMU 1.1.0 the audio stream contains only bytes of zeros, 
so this results in no sound on the client.

It is almost like the stream is muted by sending 0 bytes instead of the 
actual data.

0:   VNC: :SOUND: AudioOn
1:   VNC: :SOUND: Received _QEMU_Audio_Server_Message: Operation: 1
2:   VNC: :SOUND: Received _QEMU_Audio_Start
3:   VNC: :SOUND: Received _QEMU_Audio_Server_Message: Operation: 2
4:   VNC: :SOUND: Received _QEMU_Audio_Data 0 0 0 0 0 0 0 0 0 0 0 0 0 0 
0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0

Is there something new that needs to be done in order for the sound to 
be pushed out, like some unmute mechanism?

I rebuilt QEMU 0.15.1 and sound worked but was very choppy, I think due 
to some timer injection changes - but that's another issue.

Thanks in advance.
