Have video, no audio (live)

[ifrisbie]

I have audio renderer set to default and all audio decoders set to LAV Audio Decoder. I've altered just about every LAV option I can think of on AC3 decoder to try to get the audio to play to no avail.

Channel has two audios so I know streams are present - although I don't know how with nPVR you are supposed to be able to select between them (no check mark present indicating which one is currently selected).

I have VIA HD audio chipset that is working just fine.

Anyone have any suggestions? Any ideas what the actual settings on the LAV Audio Decoder property tabs should be for AC-3? Any way to get more details from the audio stream itself?

If you enable the taskbar icon and then play a recording you can being up lab audio during playback and go to the status tab to see what the audio format is

Well, since there is one icon for every decoder then I'd have to know what the expected format is first. I have MP1 and AC3 currently enabled so two icons exist. Neither seem to have anything of interest on the status screen while I'm playing the video that was recorded. I suppose if I knew the format I might get some details - but I'm not sure how this helps me identify the decoder/format in use.

Anyone else?

If this is US OTA digital TV, it is almost certainly AC3. My cableco is AC3 as well. Analog off a cable box is MPEG1. I use AC3Filter for the audio decoder (both AC3 and MPEG1) with no problems. I think others have reported some issues with the LAV decoders.

Right mouse click on the playing video and you should be able to select the audio stream. I have never used this, though.

I'm also using AC3Filter, but many are using LAV for AC3. Is the PC's default playback device set to Speakers, HDMI Output or Digital Output? You mentioned that at least one channel has two audio tracks. Are they both [AC3, eng]? Maybe try clicking on Track 2 and see what happens.

Thanks! It took some adjustments but I got AC3Filter to work.
