Re: HDMI audio not working once X starts
I realize you have the same problem, I was hoping for some help though. Let me also say that the latest 96.xxx (or 173.xxx for that matter) series drivers have the same audio problem. I haven't been able to come up with a patch for 100.14.19 on kernel 2.6.27, so I can't validate that being a solution/workaround for me.
I just can't think of anything nvidia be doing to the audio subsystem when X starts that would cause it to be broken.
If I restart alsa inside X the audio remains broken. However, if I shut down X, then restart alsa, I get the audio back. Start X again...audio broken once again. Frustrating!
