I have a very similar problem, however, sound is not going through HDMI but through internal analog audio to external speakers. When LG LED TV is put on standby, there is no sound on external speakers. Box is used as HTPC for music and radio.
It seems that sound events are put in a queue. When volume up or down is pressed, there is a usually a beep sound. When volume up or down is pressed while TV is on standby, nothing can be heard. But when TV is turned on again, there is a series of beeps heard, as many as volume up and down is pressed. Same for mute key. Ubuntu is 12.04, card is HD4250, and desktop is Cinnamon. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to fglrx-installer in Ubuntu. https://bugs.launchpad.net/bugs/1001842 Title: No Audio from HDMI After Switching Monitor Off / On To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/fglrx-installer/+bug/1001842/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
