[Desktop-packages] [Bug 974963] Re: [soundnua]: hdmi audio missing in sound settings
Hi David I don't know whether this is the right forum to continue with my problem. No doubt someone will tell me if I need to raise it else where. In any event if someone stumbles on this as I did then they may find my comments useful. I think I know what is going on in my case. When the PC powers up without the TV switched on. There is no handshake between it and the TV over the HDMI cable. The video driver defaults to the expected value but the system disables the video codec. When the TV is switched on, it does not trigger a restart of the video flgrx driver and in turn the audio remains disabled. (Wouln't it be nice if the system detected the TV and this triggers a X server restart.) I base this on my observations that a HDMI cable unplug and replug triggers a X restart and audio appears. That if I kill the video with "sudo pkill X" in a terminal and relogon the audio appears. If I start the PC after the TV has been switched on the audio appears. The pin 3 results are as you describe above. Further reading of forum messages on here and elsewhere seems to show that many have overcome this problem by installing the newer video drivers from AMD website. The Ubuntu ones are old and the post release fglrx update in Additional drivers does not work for me and many others from what I can see in the forums. I have not had success installing a newer driver from the AMD site, the process fails for me. I have even tried the latest beta version which apparently has Ubuntu support. I need to pursue this when I have time. I am sure that if Ctrl-Alt-Backspace was available that would be an easy way to restart the x server and the situation would be acceptable. With Mybuntu I can't enable the feature on the keyboard. I have seen that Alt (Right)- K-PrintScreen restarts the X server but not for me. I am able to add buttons to the mythtv frontend (I have buttons to Power_off and Reboot). I think I will add a button to kill the X server and it will restart. This is fine but the process does not remember that it should autologin but that is better than continually unplugging and replugging in the HDMI cable. Anyhow, that is as far as I have got.

[Desktop-packages] [Bug 974963] Re: [soundnua]: hdmi audio missing in sound settings
Hi David Thank you for responding quickly. No I don't recall unplugging it after 90 seconds. And, I know the HDMI cable is good because I swapped it when I first found the fault, and looking at dmesg I could see something about HDMI pin3. I use this machine with Mythbuntu and the machine comes on at a set time from the bios rtc. The TV is switched on later. I have noticed that if I power the PC after switching on the TV then I do have sound (this is my perception and I need to record if this is 100% true on all occasions). I am not sure what you mean about seeing it in sound settings. In Mythbutu this is Frontend/Setup/Audio and can only be seen after it has booted. I think that, in the past, when I have looked at it, it had a comment "Not Connected", but looking today this is not there. In the past I have tried changing drivers back to others and back to the HDMI one without getting sound. Unplugging and replugging seems the only thing I can do if I don't want to reboot the system Below is a test results from the kernel log that I have just done. I booted up with the TV off and got no sound. I then unplugged and plugged back in the HDMI cable and got sound. I can see that the lack of sound may be due to the fglrx (Radeon) drivers? And that the unplug/Replug in event caused something to happen which got me sound.

If so, I can add a Sound Button to the MythTV front end that calls up this script and I am fine. At least it will keep my wife happy. Thank you for your endevours so far.

Hi David I too have the HDMI sound problem. System E350M1 card with 64 bit mythbutu 12.04 with all the updates up to 25 September on it. The card has the Radeon Graphics hardware on it. Sound can be restored by unplugging and plugging the HDMI lead back in. I sometimes have the PC start up without the Samsung TV on and, it may be my imagination, but then HDMI sound will not work. Have been experimenting with /etc/init.d/xxx restarts to no purpose I see no one else has given you a copy of their log and have attached one to aid you if you need it.
