As I’ve mentioned elsewhere, I really like what I’ve read about the structure of Podium projects. Unfortunately, none of it is much use to me at the moment because I can’t get any sound out via the ASIO drivers of my M Audio Delta Audiophile 2496 sound card. This card has up-to-date manufacturer supplied ASIO drivers, which work when every other audio app I use (e.g. Fruity Studio, Cool Edit, Audacity + recently Plogue Bidule and Audiomulch).
I did get sound out when I used the MME drivers, but that is not workable for me because of the appalling latency compared with what I can get from the ASIO drivers in the other apps. And, like I said, all the other apps work fine with the ASIO drivers, so I think Podium should also.
The card has 6 inputs (3 stereo pairs) and 4 outputs (2 stereo pairs). I’m not interested in the inputs at the moment, just the outputs. I’ve selected the Delta ASIO driver in the MIDI/Audio Interfaces dialog. The project wizard claims my audio mixer mappings appear to be OK. I’d dearly like to know where I can configure these mixer mappings, as there’s nothing in the Setup or New menus that appear to resemble mixer mappings.
At a guess, “mixer mappings” might mean the Master Stereo and Master Mono device mappings (hint: in all user output in the application, you must be careful to ensure that your terminology is always consistent – don’t use one term in one dialog, and a different term elsewhere). And this is where I get really confused, despite the documentation at http://www.zynewave.com/guide/guide22_mappings.htm. I can’t see anywhere where I can select which of the the Delta’s outputs to use. In fact, I can’t even explicitly select the Delta at all. The only two choices for audio interface are and . I’d expect to see the Delta AP listed here, preferably split into a choice of outputs.
And I have no idea what the starting target channel number in the Audio Configuration box is supposed to represent. Maybe it is meant to be the Delta’s outputs, but there is no hint anywhere that this is the case. Regardless, I selected each channel from 1 to 33 and tried playing the demo project, with no sound. The sound meters moved in channels 1 to 4, but froze for all the channels afterwards.
I hope I’m just missing something obvious here, but I’m not a clueless newbie with computers in general or audio apps in particular. And I’ve spent several hours over two nights on this now.
Oh, and here is the report:

I’m intrigued by the “Output buffer skip count: 2” message. What on earth does that mean?
