No sound in X when connected via HDMI
First, a description of my configuration:
I have a C-Media Electronics Inc CM8738 sound card. This sound card is connected to my television via the front channels output. In addition, the SPDIF/out is connected to my GeForce 8500GT. My GeForce 8500GT is then connected to my television via an HDMI cable.
Now for the problem:
Prior to a recent upgrade, sound was being delivered to my television via the analog out on my sound card. I am sure I was using a 169.xx version of the nVidia drivers before the upgrade. So there was no way for audio to be delivered via the HDMI cable. I was unaware at the time I upgraded that this feature had been implemented in the 173.xx drivers. Upon discovering this, I un-muted the IEC958 device on my sound card via alsamixer. This, however, did not give me sound.
As it stands, I am able to play sound on the console before starting X. E.G.:
I do not want to use a VGA connection to "solve" this problem. The picture is blurry, and the picture shifts to the left or right when X is initializing. That is, if I connect via VGA I cannot see the whole picture because the display is not detecting properly.
I need a solution to this audio of HDMI problem. Please, I have run out of ideas on what to try.

Note: please ignore the errors about "mythlogin" in the bug report log. They are completely irrelevant to the problem, and are a result of a programming error I made earlier today.
Re: No sound in X when connected via HDMI
I have "resolved" this problem by using the instructions at
However, I do not see this as a solution. There needs to be an option that allows us to disable audio over HDMI. Blindly assuming that it will work, even if the system is setup for it to work (as mine is!), is unacceptable.
