This works as expected.

This works as expected.

The Analog Surround 7.1 profile does show in PA. Thanks!

There is one issue regarding the per channel volume. I am jacked into
"Side Right" channel, but adjusting the Side Right channel volume in
the output tab of pavucontrol doesn't change the volume - only the
"Front Right" volume slider affects the volume. Digging further
(jacking into each channel and sliding the per channel volumes) only
the Front Left/Front Right channels adjust the volume for any of the
channels.

Front Left (1) will affect: Front Left (1), Rear Left (3), Front
Center (5), Side Left (7)
Front Right (2) will affect: Front Right (2), Rear Right (4), Front
Center (5), Side Right (8)

The "subwoofer" or "Rear Center" channel (6) did not output any sound
when I played my ogg123 -d pulse. However, the speaker-test was
successful in outputting sound out that channel.

It is both conceivable and highly likely that I misread,
misunderstood, or mis-remembered the card's capabilities.

Thanks for all your help, Alexander!
