Volume icon disappears from notification tray after connecting with VNC
I am running a CentOS 6.4 system with a VNC server configured. I can connect to the box from a remote system with a VNC client, but then when I return to the real system the volume icon has disappeared and my box has no sound. The only way I've found to correct the problem is to reboot my box.

Is there a way to restore the volume control icon and get my sound back through some other means?

Do either of these two work?

As root or with sudo privileges:

service alsa restart


service alsa-utils restart

Or check in your menus, there is sometimes a GUI util for restarting services.

I just rebooted my box so my volume icon has been restored, but I will try that the next time it happens....

In fact, I don't have either one of those services on my CentOS box. I do have two tools, gnome-volume-control and gnome-volume-control-applet. I believe the second of these is the app that actually displays the icon in the tray. Running it manually doesn't solve the problem though. I suspect I have to somehow reload the kernel driver controlling my sound, but I'm not sure just what driver is being used. Seems to be a lot of sound related modules.

Oh well, time to reboot again...

Maybe some of the info here could help:

Another command you could try:

alsactl restore <card #>

First card number would be 0.

Do you have pulseaudio running? It's not necessarily a factor but it could be.

Perhaps try a different VNC client?

A different VNC client might be a useful experiment. I'll give it a try. Thanks...
