I'm not using any input right now; playback only. I normally run jack

pulse and jack share the delta card via whatever mechanism Fedora uses
(I don't know how this works, but jack takes over and all pulse
clients go quiet).
The problem is pulse clients (e.g. banshee, firefox) playing back on
the delta 66.
I've had a Delta 66 PCI audio card for over a
decade, and it's always
sounded great. I recently had to transfer it to a new PC with a fresh
install of Fedora 17. Now, when I play anything using any pulseaudio
client, I get a strange digital noise (sort of like static, but almost
like
aliasing too).
This does NOT happen when running jack, as far as I can tell.
Aside from disabling or uninstalling pulseaudio, is there anything else I
can do? Does anyone else have this problem?
I also have a d66, but have not had that problem. Running Ubuntu, but that
shouldn't make a difference.
Are you using spdif for an input? What sample rate do you normally use
with jack? (pulse defaults to 44100) Does pulse have access to the
internal card? Are you bridging pulse-jack? or just having problems pulse
direct the d66?
Latency should not be a problem with pulse on it's
own. The only problem I
have had with pulse has been with it having interaction between the
internal audio IF and the d66 when bridging... and with a netbook mic
which was 48000 only. I have had less problems setting pulse to default at
48k.
After figuring out how to change pulseaudio's sample rate (added
"default-sample-rate = 48000" to /etc/pulse/daemon.conf) the problem
*may* have gone away. It's not happening right now, anyway.
Thanks for the suggestion, Len.
