re: "you could point PA to the motherboard soundcard"<br><br>That would seem to be the most sensible alternative; however, with the RME card installed my motherboard soundcard is not recognized by alsa. At least I presume this to be so from what is reported in /proc/asound/cards :<br>

Would it be correct to assume that in the later incantation in the same setup string that reads "sink_name=HDSP_PLAYBACK" the substring "HDSP_PLAYBACK" is arbitrary? <br>
<br>Clearly I'm not the only one confused by the ingredients in this magic sauce. By way of example, I invoked one of the games on the system, "Shinsen-Sho", that makes the occasional noise, to see how something of that sort would function with my sound settings.

I simply deleted pulseaudio, which seems to interfere with the RME cards<br>
(at least the 9632). What's the rationale to use it?<br>

Pulseaudio allows applications so share a soundcard. So you can have, say, desktop notification sounds, the browser plugins and similar applications share the soundcard. AFAIK PA appears to them as an ALSA device and is, by default, what ALSA apps use if they use the "default" device.<br>
<br>
RME cards don't have a (usable by PulseAudio) multichannel profile so PA does not know what to do with them - same thing happens on Envy24 cards, this is probably a bug in alsa although it is questionable if a profile could be built for them that has any meaning. If you define a profile for them then PA is able to use RME cards. Of course that might not be what you want (ie: you do _not_ want a random desktop event to send a beep to the soundcard while you are recoring). In that case you could point PA to the motherboard soundcard or something else and it would leave the RME alone.<br>

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