[PlanetCCRMA] setting up new system with Delta 1010LT + Intel HDA

Tue Nov 24 19:37:44 PST 2009

Another clue:  when I try # aplay <some file>.wav here's what I get:

[root at localhost bruce]# aplay /usr/share/sounds/purple/alert.wav
ALSA lib pulse.c:229:(pulse_connect) PulseAudio: Unable to connect: Connection refused

aplay: main:608: audio open error: Connection refused

I've read that PulseAudio and ALSA don't play together as well in Fedora10 as in F11 -- is upgrading to F11 recommended for inhabitants of Planet CCRMA?  The web pages don't seem to indicate that (yet?).

Well, I was hoping desktop sounds, firefox and others who use Pulse Audio (about which I know nothing, BTW) would be able to use the built-in HDA card and the speakers I have hooked to it (and that the 1010LT would handle only audio to or from JACK-aware applications).  I'm not sure what's happening when I select various 'Output Devices' on the KDE System Settings | Multimedia dialog and click the '>Test'  button.  I get sound from the HDA card when I select it, but I also get sound from it when I select PulseAudio or the Delta 1010LT.

Here's a possible clue: when I first tried testing the PulseAudio output device, I got a momentary pop-up error message (from the KDE task bar, at the lower right corner of the desktop) saying that PulseAudio was not working and the sound processor (ALSA?) was reverting to the default device, i.e. the HDA card.  I haven't been able to get the message to reappear, but maybe it doesn't repeat after the first notification (?), in which case maybe I just missed a similar message the first time I tested the Delta 10101LT.  It seems like that could explain why I get sound from the HDA card when I test the Delta 1010LT.

In any case, I think I need to learn about PulseAudio, ALSA, and how they live together on the same system in order to trouble-shoot the system side of my sound setup.

Good to know. 

You can't use jack and have firefox doing stuff in the same soundcard
(there's a trick for that of course :-)

Desktop sounds, firefox and others use Pulse Audio for sound. So to try
that first stop jack. You have to see which card Pulse Audio is using.
In fc10 I _think_ that was pavucontrol (there might be a problem with
pulseaudio recognizing the 1010lt in fc10). See what that shows...
