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. > If that succeeds, I will post the formal patch to the alsa-devel list. > > As for the second SPDIF, sorry, I think there is some misunderstanding here. > According to the reviews, the card has one spdif input and one spdif output, > both of which are already supported. It is both conceivable and highly likely that I misread, misunderstood, or mis-remembered the card's capabilities. Thanks for all your help, Alexander! Sincerely, -mz
