Have you configured PA manually to use those hw:0,0,0 devices? Why?
Don't do that! Always use devices like 'front:0', 'surround51:0',
'spdif:0' or suchlike. The raw devices lie 'hw:0' are only for very
few cases useful, and those with specified devices, and subdevices
even more so.

Many sound cheap sound cards cme with three stereo chips which are
combined in software to a 6ch stream. ALSA does that in userspace. If
you access the device as 'surround51:0' as you should this is dealt
with. If you use raw device strings like 'hw:0' this does not take
place.

Are you sure? Given the sampling frequency sound card 1 seems to be a
modem.
