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.
