[pvrusb2] Hauppauge HVR-1900 - PAL-Nc, no audio

Thanks for the response Lorne.
Sound works ok on the machine (and in fact I've tried the device on two others - all with working audio).
But I'm inclined to believe that the issue is lower level than that anyway (note that the mpeg I've linked to has an mp3 48kHz audio stream, but it's simply silence).
My own guess (and it is just that), is that this could be one of two things:
1. The audio tuning is wrong for PAL-N/Nc. The "norm" for PAL would be either 5.5 or 6.5MHz offset from the video tuning. But for PAL-N/Nc, the offset should be 4.5MHz. (so for the example I gave below, with video at 163.25MHz, the correct audio tuning would be 167.75MHz). I don't know any way to specifically check (or set) the audio tuning however, so I don't know how to check this. I had a look through the pvrusb2 source to see if I could work this out, but I couldn't find anything relevant.
or
2. Audio here generally has 2 audio streams (they call the second the "SAP" stream, I believe it's a variation on MTS used in NTSC). The primary stream would generally be in spanish, and the second stream in english. Possibly this is confusing things (but, if this is truly the issue, I would expect to get *some* audio, rather than just the current silence).
Maybe I'm digging a little bit too deep here, it might be just something silly like the audio being switched off somewhere (but note that I've tried explicitly setting the audio input also via: v4l2-ctl -d /dev/video1 --set-audio-input=0)
