OK, finally something interesting.
I installed the same kernel on the laptop as on the desktop, Debian
pre-built linux-image-2.6.18-3-686, and now the laptop now longer plays
stereo. It behaves the same as the desktop. I can boot back and forth
between the two kernels, and the old one comes back stereo; the new one
mono. In both cases (and on the desktop) I haven't updated anything to
with video/sound except for the pvrusb2 snapshot.
Mike - what kernel version do you run when you test your 29xxx device?
In light of this, what is the next step?
Here are two sets of log info, both from the laptop. The first is the
2.6.18 kernel with mono sound; the second from 2.6.15 with stereo.
