How does descriptive audio work? This is the additional descriptive audio for the visually impaired that describes what is happening on the screen ("A man wearing a trenchcoat walks into a dark room"). For the Seattle PBS station that I tune with clear QAM, I sometimes get this audio, especially Masterpiece Mystery. Do I have the wrong audio stream/PID selected in the channel mapping? Or, did the station do something wrong? (Would not surprise me.) I can't verify that this does or does not happen when I watch the channel on TV, I'm pretty sure it doesn't, though.

The channel scan has 2 audio programs for this channel, ID'd as:
106.1 KCTSHD*(000) A:2049
106.1 KCTSHD*(000(AC3)) A:2050

I have the one ID'd as AC3 mapped, all the other channels only have a singe audio program. Should I have the non-AC3 one mapped? I don't need AC3 as I don't use surround sound.

Thanks for the insight folks.

You could try running the channel scan when Masterpiece mystery is on?

Then check the 2 audio streams to see which one is best. (or you could create a test channel and map the other audio stream to it, then check when you notice the ac3 stream is playing the wrong audio)

Figured it out. I should have done my homework before posting. I needed to map the non-AC3 audio stream. The AC3 stream carries the descriptive audio. Using the TV, I found that the current program had descriptive audio, so checked the channel mapping in config and confirmed the AC3 stream was the one.

I don't believe PVRX2 has audio track selection capability, but NPVR does? (Not that it makes much difference now.)

That's correct.
