I've tried different codecs and nothing works out. Also, audio is being sent to my receiver via HDMI which leads into my next questions
What are you guys using for audio on your HTPC nowadays? I use to look into this and there were HDMI sound cards but it seems like now, everyone just use their video cards via HDMI? If that's the case, what video card would you recommend as say the best of the best? I'm using the onboard video card for audio as well and I think that is limiting me....
Most broadcast cable only delivers AC3 2.0 and rarely 2.1/5.1
I probably receive about 6 channels in 5.1 and the others in 2.0 (all AC3)
That being said, AC3 is pretty ubiquitous when it comes to video cards (in other words - it'd be difficult to buy a new one that "didn't" support it)
TrueHD and DTS-HD are supported on new cards from NVIDIA and AMD, as well as Intel integrated (for at least 2 yrs now)
For intel, the audio feed is handed off to the PCH, so it doesn't really matter which intel motherboard/processor you use (disregard onboard video decoding options as well) as long as it's Sandy or Ivy (no reason to use clarkdale)
Bitstreamed audio is passed through the video card or integrated video, so the question of "which video card would be the best of the best?" in regards to audio is similar to saying "Which filesystem is the best for copying a zip file to a flash drive?" - it has no effect
For the other part, I'm curious as to which channel is affected
For Comcast users in WMC, there was an issue (which may still be unresolved) where you had to select the second audio track in the broadcast to hear anything. This applied to the CW HD channel. The broadcast contained 1080i mpeg2 video and (2x) ac3 2.0 audio streams. WMC would default to the first one (which worked for every other channel) but for some reason the CW HD broadcast had everything in the 2nd audio track (which is usually for music and special effects). You had to manually select the second track every time in WMC to watch it, but the DVR/STB boxes from Scientific Atlantia never encountered this problem.
Someone who knows more about TV broadcast / WMC troubleshooting would have to help out, but the thread I recall is this one
. However, the solution is more of a band-aid in my opinion
