Thanks Colin,<br>
<br>
that's a great suggestion and I will follow through on it. <br>
<br>
This does bring to mind a similar issue regarding ALSA setup
catering to the special requirements of sound devices meeting
diverse user requirements. We were for several years directed to
accomplish this through specially tailored .asoundrc files. Have
these been deprecated?<br>
<br>
-- <br>
<br>
Another issue to explore in the general context of the interaction
of Pulseaudio and ALSA on my system is if Dbus is properly
configured and operating properly.<br>

<pre wrap="">Hiya,
It would be great if you could write a "profile set" for this card.
Profile sets are particular "probing rules" that explain to PA exactly
how you want to work with a given card.
It's generally used for the more "pro" end of the market.
These profile sets can be written without recompiling PA, and can be
found in:
/usr/share/pulseaudio/alsa-mixer/profile-sets
If you look in that folder you'll already see a few definitions:is
default.conf
maudio-fasttrack-pro.conf
native-instruments-audio4dj.conf
native-instruments-audio8dj.conf
native-instruments-korecontroller.conf
native-instruments-traktor-audio10.conf
native-instruments-traktor-audio6.conf
native-instruments-traktorkontrol-s4.conf
(I'm running git master so I may have a few more than you)
You assign specific profiles to your card via udev rules:
/lib/udev/rules.d/90-pulseaudio.rules
The files should be (mostly) self contained with regards to how to
configure them (I'm not really an expert, but if you need help, please
post on the PA mailing list!)
If you managed to write a good profile-set that works to your
satisfaction, I'll be more than happy to include the patch upstream.
This might not be the only thing needed as things like default rates
etc. may need to be set in daemon.conf...
If this doesn't work, I'd still recommend keeping udev-detect, but
simply setting the card to Off profile before loading the sink directly
with the appropriate args. This way you still get hotplug support :)
Another tip to not mess with your system default.pa, you can do this in
your ~/.pulse/default.pa:
.include /etc/pulse/default.pa
; Do custom stuff below....
load-module module-alsa-sink......
Hope this helps.

<pre wrap="">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

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?

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.
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).
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?)

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.
Note that you will need to adjust number of channels and name of the
soundcard to match what you have...
