[Ubuntu-x-swat] [Bug 1001842] Re: No Audio from HDMI After Switching Monitor Off / On
I was able to work around this problem by using the xorg.conf option "CustomEDID". The goal is to essentially tell the system to pretend that your particular model of monitor/TV is always connected to the port in question. First, run this to determine the name of the video port in question: xrandr -d :0 --auto Then, generate an edid file with the 'get-edid' utility. You can pipe the output into the edid-decode utility to see it, and eventually output it to a file (I used /root/edid.bin). Then add something like this to your /etc/X11/xorg.conf, inside the "Device" section: Option "UseHotplugEvents" "False" Option "ConnectedMonitor" "HDMI-0" Option "UseDisplayDevice" "HDMI-0" Option "CustomEDID" "HDMI-0:/root/edid.bin" Where HDMI-0 is the video port name you got from xrandr. If you don't already have an xorg.conf file, you'll need to make one somehow. The "nvidia-xconfig" executable worked for me, but I'm sure it will vary depending on the video card and driver in question. WARNING: I've read that using the CustomEDID option with an incorrect edid file (such as one for the wrong monitor or a different port) can cause hardware damage! -- 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

i have the same issue too with ubuntu 16.04 mate, but also i have changed my distro to Arch Linux and have the same issue, so i dont think its limited to to Ubuntu. The other issue is that the bug is intermittent. sometimes it happens other times its not. I cannot work out what triggers this bug. the chip im using is: 00:02.0 VGA compatible controller: Intel Corporation HD Graphics 520 (rev 07) its a new machine.

[Ubuntu-x-swat] [Bug 1001842] Re: No Audio from HDMI After Switching Monitor Off / On
On Ubuntu 14.04.1 LTS, another workaround is to go to the Display settings and change the resolution of the (hdmi) display temporarily. For example, set to a lower resolution and then let it time out (do not accept the changes). The HDMI "Play sound through" option is then available in the sound settings again. -- 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

Confirmed this bug with Ubuntu 12.04.2 LTS.

[Ubuntu-x-swat] [Bug 1001842] Re: No Audio from HDMI After Switching Monitor Off / On
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.
