[PlanetCCRMA] RME 9652 - ALSA - Pulseaudio problems

re: "you could point PA to the motherboard soundcard"

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 :

0 [DSP            ]: H-DSP - Hammerfall DSP
                      RME Hammerfall HDSP 9652 at 0xfdee0000, irq 17

I appreciate your earlier clarification on the portion of this information,
i.e.,   " [DSP            ]",  that is needed for in the setup string that
the user is expected to craft for /etc/pulse/default.pa , in particular the
portion that reads "device=hw:DSP" for my system. 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?

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. The first event that
occasioned sound output from the application produced the error message

"Can't find device RME Hammerfall HDSP 9652. Using instead device RME
Hammerfall HDSP 9652."

Go figure!
