I tried setting it to Capture.
No joy. ALSA gets wedged just the same as before.
By the way, is this DMA Allocation thingy documented anywhere?????
I had to do a huge find|grep to figure out what this
suggestion was referring to. Alsamixer knows nothing
of this switch. Amixer knows nothing of this switch.
Fortunately alsactl can deal with it.
From the keen-grasp-of-the-obvious department:
This project would be a lot better off if there were
better documentation, and (some) comments in the code.
Why write the code if it's not going to be used?
If it's not documented, it's not going to be used!

I haven't been messing with that.
But thanks for the hint; I'll fire up the oscilloscope and
take a look when I get a chance.
