So everything seemed to be working great, or so I thought...
Third day in a row, no sound from live TV in the morning, or when kids get home from school. (of course its when Im not there!)
I always leave the HTPC on, just turn the tv off at night. I turned off all of the sleep functions I can find in windows. My wife gets up in the morning and turns the tv on. Live tv is playing but there is no sound. You can hear all of the pc sounds from WMC but no audio from love tv. You have to restart WMC for it to work. (not a big deal to me but takes major points away from the WAF).
This just started a few days ago, not sure why. I am running wn7 64bit, ceton infiniTv 4 tuner. Connected via HDMI directly to my tv. No sound card, just the onboard realtek audio from my asus mobo.
It must be some sort of sleep function that im missing. I can not duplicate the problem by just turning off the tv for a few mins. It has to sit for several hours.
