Thanks, I followed this advice and now Pulseaudio is no longer
carping. I will do further testing within the next week and report
back in more detail. Meanwhile, here is the changed info in the
default.pa that I modeled on your example and the characteristics of
the RME9652<br>

This has me wondering if support for our cards' higher sampling rate
is as simple as using "rate=96000" and adjusting the number of
channels. What do you think?<br>

PS Near as I can tell the designation HDSP is also valid for my card
(though I would feel more comfortable if there were documentation to
refer to so that I did not have to guess). Similarly (but with the
same level of uncertainty) the hw designation DSP seems correct for
my card too.<br>
<br>
As to the question on the list to the effect "why use pulseaudio at
all?" -- Outside of the Music and DAW chores there are a number of
applications (audio file players, streaming audio, etc) that also
use the sound card and it seems perfectly sensible to have them
default to pulseaudio (once I repair my setup). <br>
<br>
Colin Guthrie suggested moving from Fedora to a different
distribution. System administration chores are easier for me on
Fedora in that they still show their Unix origins more clearly that
others (e.g., Ubuntu) and after several decades of habituating
myself to that environment Fedora seems a better fit for me. While I
remain confident that with your help I can repair the audio problems
that plague my system, were that not the case, I would be more
likely to reinstall Fedora with the 64 bit Intel kernel (for the
general performance boost) than to switch to another 32 bit
distribution on the off-chance that it might provide better audio
support. (After all, if I could not have audio any way, what would I
have to loose?)<br>

By default PA can't use an RME card out of the box as it can't
find a default mapping for all the available channels. There is a
workaround that involves telling it explicitly. I'm attaching a
file that I use for our RME Multiface II cards.
<br>
<br>
Note that you will need to adjust number of channels and name of
the soundcard to match what you have...
